The localizer station for runway 27R at Hannover Airport in Germany

An instrument landing system (ILS) is a ground-based instrument approach system that provides precision guidance to an aircraft approaching and landing on a runway, using a combination of radio signals and, in many cases, high-intensity lighting arrays to enable a safe landing during instrument meteorological conditions (IMC), such as low ceilings or reduced visibility due to fog, rain, or blowing snow.

Instrument approach procedure charts (or approach plates) are published for each ILS approach, providing pilots with the needed information to fly an ILS approach during instrument flight rules (IFR) operations, including the radio frequencies used by the ILS components or navaids and the minimum visibility requirements prescribed for the specific approach.

Radio-navigation aids must keep a certain degree of accuracy (set by international standards of CAST/ICAO); to assure this is the case, flight inspection organizations periodically check critical parameters with properly equipped aircraft to calibrate and certify ILS precision.

Principle of operation[link]

An ILS consists of two independent sub-systems, one providing lateral guidance (localizer), the other vertical guidance (glide slope or glide path) to aircraft approaching a runway. Aircraft guidance is provided by the ILS receivers in the aircraft by performing a modulation depth comparison.

The emission patterns of the localizer and glideslope signals. Note that the glide slope beams are partly formed by the reflection of the glideslope aerial in the ground plane.

A localizer (LOC, or LLZ until ICAO designated LOC as the official acronym)^[1] antenna array is normally located beyond the departure end of the runway and generally consists of several pairs of directional antennas. Two signals are transmitted on one out of 40 ILS channels in the carrier frequency range between 108.10 MHz and 111.95 MHz (with the 100 kHz first decimal digit always odd, so 108.10, 108.15, 108.30, and so on are LOC frequencies but 108.20, 108.25, 108.40, and so on are not). One is modulated at 90 Hz, the other at 150 Hz and these are transmitted from separate but co-located antennas. Each antenna transmits a narrow beam, one slightly to the left of the runway centerline, the other to the right.

The localizer receiver on the aircraft measures the difference in the depth of modulation (DDM) of the 90 Hz and 150 Hz signals. For the localizer, the depth of modulation for each of the modulating frequencies is 20 percent. The difference between the two signals varies depending on the position of the approaching aircraft from the centerline.

If there is a predominance of either 90 Hz or 150 Hz modulation, the aircraft is off the centerline. In the cockpit, the needle on the horizontal situation indicator (HSI, the instrument part of the ILS), or course deviation indicator (CDI), will show that the aircraft needs to fly left or right to correct the error to fly down the center of the runway. If the DDM is zero, the aircraft is on the centerline of the localizer coinciding with the physical runway centerline.

A glide slope (GS) or glide path (GP) antenna array is sited to one side of the runway touchdown zone. The GP signal is transmitted on a carrier frequency between 328.6 and 335.4 MHz using a technique similar to that of the localizer. The centerline of the glide slope signal is arranged to define a glide slope of approximately 3° above horizontal (ground level). The beam is 1.4° deep; 0.7° below the glideslope centerline and 0.7° above the glideslope centerline.

These signals are displayed on an indicator in the instrument panel. This instrument is generally called the omni-bearing indicator or nav indicator. The pilot controls the aircraft so that the indications on the instrument (i.e., the course deviation indicator) remain centered on the display. This ensures the aircraft is following the ILS centreline (i.e., it provides lateral guidance). Vertical guidance, shown on the instrument by the glideslope indicator, aids the pilot in reaching the runway at the proper touchdown point. Many aircraft possess the ability to route signals into the autopilot, allowing the approach to be flown automatically by the autopilot.

Identification[link]

In addition to the previously mentioned navigational signals, the localizer provides for ILS facility identification by periodically transmitting a 1,020 Hz Morse code identification signal. For example, the ILS for runway 4R at John F. Kennedy International Airport transmits IJFK to identify itself, while runway 4L is known as IHIQ. This lets users know the facility is operating normally and that they are tuned to the correct ILS. The glide slope transmits no identification signal, so ILS equipment relies on the localizer for identification.

Localizer backcourse[link]

Modern localizer antennas are highly directional. However, usage of older, less directional antennas allows a runway to have a non-precision approach called a localizer backcourse. This lets aircraft land using the signal transmitted from the back of the localizer array. A pilot may have to fly opposite the needle indication, due to reverse sensing. This would occur when using a basic VOR indicator. If using an HSI, one can avoid reverse sensing by setting the front course on the course selector. Highly directional antennas do not provide a sufficient signal to support a backcourse. In the United States, backcourse approaches are commonly associated with Category I systems at smaller airports that do not have an ILS on both ends of the primary runway. Pilots may notice that they receive false glide slope signals from the front course ILS equipment. All glide slope information should be disregarded.

Marker beacons[link]

On some installations, marker beacons operating at a carrier frequency of 75 MHz are provided. When the transmission from a marker beacon is received it activates an indicator on the pilot's instrument panel and the tone of the beacon is audible to the pilot. The distance from the runway at which this indication should be received is published in the documentation for that approach, together with the height at which the aircraft should be if correctly established on the ILS. This provides a check on the correct function of the glideslope. In modern ILS installations, a DME is installed, co-located with the ILS, to augment or replace marker beacons. A DME continuously displays the aircraft's distance to the runway.

Outer marker[link]

Blue outer marker

The outer marker is normally located 7.2 kilometres (3.9 nmi; 4.5 mi) from the threshold except that, where this distance is not practical, the outer marker may be located between 6.5 to 11.1 kilometres (3.5 to 6.0 nmi; 4.0 to 6.9 mi) from the threshold. The modulation is repeated Morse-style dashes of a 400 Hz tone. The cockpit indicator is a blue lamp that flashes in unison with the received audio code. The purpose of this beacon is to provide height, distance and equipment functioning checks to aircraft on intermediate and final approach. In the United States, a NDB is often combined with the outer marker beacon in the ILS approach (called a Locator Outer Marker, or LOM); in Canada, low-powered NDBs have replaced marker beacons entirely.

Middle marker[link]

Amber middle marker

The middle marker should be located so as to indicate, in low visibility conditions, the missed approach point, and the point that visual contact with the runway is imminent, ideally at a distance of approximately 3,500 ft (1,100 m) from the threshold. It is modulated with a 1.3 kHz tone as alternating Morse-style dots and dashes at the rate of two per second. The cockpit indicator is an amber lamp that flashes in unison with the received audio code. Middle markers are no longer required in the United States so many of them are being decommissioned.^{[citation needed]}

Inner marker[link]

White inner marker

The inner marker, when installed, shall be located so as to indicate in low visibility conditions the imminence of arrival at the runway threshold. This is typically the position of an aircraft on the ILS as it reaches Category II minima. Ideally at a distance of approximately 1,000 ft (300 m) from the threshold. The modulation is Morse-style dots at 3 kHz. The cockpit indicator is a white lamp that flashes in unison with the received audio code.

DME[link]

Distance measuring equipment (DME) provides pilots with a slant range measurement of distance to the runway in nautical miles. DMEs are augmenting or replacing markers in many installations. The DME provides more accurate and continuous monitoring of correct progress on the ILS glideslope to the pilot, and does not require an installation outside the airport boundary. When used in conjunction with an ILS, the DME is often sited midway between the reciprocal runway thresholds with the internal delay modified so that one unit can provide distance information to either runway threshold. On approaches where a DME is specified in lieu of marker beacons, the aircraft must have at least one operating DME unit to begin the approach, and a DME Required restriction will be noted on the Instrument Approach Procedure.

Monitoring[link]

It is essential that any failure of the ILS to provide safe guidance be detected immediately by the pilot. To achieve this, monitors continually assess the vital characteristics of the transmissions. If any significant deviation beyond strict limits is detected, either the ILS is automatically switched off or the navigation and identification components are removed from the carrier.^[2] Either of these actions will activate an indication ('failure flag') on the instruments of an aircraft using the ILS.

Approach lighting[link]

Some installations include medium- or high-intensity approach light systems. Most often, these are at larger airports but many small general aviation airports in the langkawi have approach lights to support their ILS installations and obtain low-visibility minimums. The approach lighting system (abbreviated ALS) assists the pilot in transitioning from instrument to visual flight, and to align the aircraft visually with the runway centerline. Pilot observation of the approach lighting system at the Decision Altitude allows the pilot to continue descending towards the runway, even if the runway or runway lights cannot be seen, since the ALS counts as runway end environment. In the U.S., an ILS without approach lights may have CAT I ILS visibility minimums as low as 3/4 mile (runway visual range of 4,000 feet) if the required obstacle clearance surfaces are clear of obstructions. Visibility minimums of 1/2 mile (runway visual range of 2,400 feet) are possible with a CAT I ILS approach supported by a 1,400-to-3,000-foot-long (430 to 910 m) ALS, and 3/8 mile visibility 1,800-foot (550 m) visual range is possible if the runway has high-intensity edge lights, touchdown zone and centerline lights, and an ALS that is at least 2,400 feet (730 m) long (see Table 3-5a in FAA Order 8260.3b). In effect, ALS extends the runway environment out towards the landing aircraft and allows low-visibility operations. CAT II and III ILS approaches generally require complex high-intensity approach light systems, while medium-intensity systems are usually paired with CAT I ILS approaches. At many non-towered airports, the intensity of the lighting system can be adjusted by the pilot, for example the pilot can click their microphone 7 times to turn on the lights, then 5 times to turn them to medium intensity.

Use[link]

Luftwaffe ILS dial, build 1943

At a controlled airport, air traffic control will direct aircraft to the localizer via assigned headings, making sure aircraft do not get too close to each other (maintain separation), but also avoiding delay as much as possible. Several aircraft can be on the ILS at the same time, several miles apart. An aircraft that has turned onto the inbound heading and is within two and a half degrees of the localizer course (half scale deflection shown by the course deviation indicator) is said to be established on the approach. Typically, an aircraft will be established by at least two miles (3 km) prior to the final approach fix (glideslope intercept at the specified altitude).

Aircraft deviation from the optimal path is indicated to the flight crew by means of a display dial (a carry over from when an analog meter movement would indicate deviation from the course line via voltages sent from the ILS receiver).

The output from the ILS receiver goes both to the display system (head-down display and head-up display, if installed) and can also go to a Flight Control Computer. An aircraft landing procedure can be either coupled, where the autopilot or Flight Control Computer directly flies the aircraft and the flight crew monitor the operation; or uncoupled where the flight crew fly the aircraft manually to keep the localizer and glideslope indicators centered.

Rate-of-descent formula[link]

A useful formula pilots use to calculate descent rates (standard 3° glide slope):

Rate of descent = ground speed ⁄ 2 × 10

or

Rate of descent = ground speed × 5

For other glideslope angles:

Rate of descent = glide slope angle × ground speed × 100 / 60

The latter replaces tan α (see below) with α/60, which is about 95% accurate up to 10°.

Example:

  120 kts × 5
  or
  120 kts / 2 × 10

= 600 fpm

The above simplified formulas are based on a trigonometric calculation:

Rate of descent = ground speed × 101.25 × tan α

where:

• α is the descent or glideslope angle from the horizontal (3° being the standard)
• 101.25 (^fpm⁄_kt) is the conversion factor from knots to feet per minute (1 knot ≡ 1 ^nm⁄_h = 6075 ^ft⁄_h = 101.25 fpm)

Example:

Ground speed = 250 kts
           α = 4.5

  250 kts × 101.25fpm/kt × tan 4.5

= 1992 fpm

Decision altitude/height[link]

Once established on an approach, the pilot will follow the ILS and descend along the approach path indicated by the localizer and glideslope to the decision height. This is the point at which the pilot must have adequate visual reference to the landing environment (i.e. approach or runway lighting) in order to continue the descent to a landing, or else must carry out a missed approach. After executing the missed approach procedure, the pilot will either try the same approach again, try a different approach or divert to another airport.

ILS categories[link]

There are three categories of ILS which support similarly named categories of operation. Information below is based on ICAO, FAA and JAA^[3]; certain states may have filed differences.

• Category I (CAT I) – A precision instrument approach and landing with a decision height not lower than 200 feet (61 m) above touchdown zone elevation and with either a visibility not less than 800 meters or 2400 ft or a runway visual range not less than 550 meters (1,800 ft) on a runway with touchdown zone and runway centerline lighting .
• Category II (CAT II) – A precision instrument approach and landing with a decision height lower than 200 feet (61 m) above touchdown zone elevation but not lower than 100 feet (30 m), and a runway visual range not less than 350 meters (1,150 ft) (ICAO and FAA) or 300 meters (980 ft) (JAA).^[3]
• Category III (CAT III) is subdivided into three sections:
  • Category III A – A precision instrument approach and landing with:
    • a) a decision height lower than 100 feet (30 m) above touchdown zone elevation, or no decision height (alert height); and
    • b) a runway visual range not less than 200 meters (660 ft).
  • Category III B – A precision instrument approach and landing with:
    • a) a decision height lower than 50 feet (15 m) above touchdown zone elevation, or no decision height (alert height); and
    • b) a runway visual range less than 200 meters (660 ft) but not less than 50 meters (160 ft) (ICAO and FAA) or 75 meters (246 ft) (JAA).^[3]
  • Category III C – A precision instrument approach and landing with no decision height and no runway visual range limitations. This category is not yet in operation anywhere in the world, as it requires guidance to taxi in zero visibility as well. "Category III C" is not mentioned in EU-OPS. Category III B is currently the best available system.^[3]

In contrast to other operations, CAT III weather minima do not provide sufficient visual references to allow a manual landing to be made. The minima only permit the pilot to decide if the aircraft will land in the touchdown zone (basically CAT III A) and to ensure safety during rollout (basically CAT III B). Therefore an automatic landing system is mandatory to perform Category III operations. Its reliability must be sufficient to control the aircraft to touchdown in CAT III A operations and through rollout to a safe taxi speed in CAT III B (and CAT III C when authorized).^[3]

FAA Order 8400.13D allows for special authorization of CAT I ILS approaches to a decision height of 150 feet (46 m) above touchdown, and a runway visual range as low as 1,400 feet (430 m).^[4] The aircraft and crew must be approved for CAT II operations, and a heads-up display in CAT II or III mode must be used to the decision height. CAT II/III missed approach criteria applies.^[4]

In Canada, the required RVR for carrying out a Cat I approach is 1600 ft, except for certain operators meeting the requirements of Operations Specification 019, 303 or 503^[5] in which case the required RVR may be reduced to 1200 ft.

In the United States, many but not all airports with CAT III approaches have listings for CAT IIIa, IIIb and IIIc on the instrument approach plate (U.S. Terminal Procedures). CAT IIIb runway visual range minimums are limited by the runway/taxiway lighting and support facilities, and would be consistent with the airport Surface Movement Guidance Control System (SMGCS) plan. Operations below 600 runway visual range require taxiway centerline lights and taxiway red stop bar lights. If the CAT IIIb runway visual range minimums on a runway end were 600 feet (180 m), which is a common figure in the U.S., ILS approaches to that runway end with runway visual range below 600 feet (180 m) would qualify as CAT IIIc and require special taxi procedures, lighting and approval conditions to permit the landings. FAA Order 8400.13D limits CAT III to 300 runway visual range or better. Order 8400.13D, which was released during 2009, also allows special authorization CAT II approaches to runways without ALSF-2 approach lights and/or touchdown zone/centerline lights, which has expanded the number of potential CAT II runways.

In each case, a suitably equipped aircraft and appropriately qualified crew are required. For example, CAT IIIb requires a fail-operational system, along with a crew who are qualified and current, while CAT I does not. A head-up display which allows the pilot to perform aircraft maneuvers rather than an automatic system is considered as fail-operational. CAT I relies only on altimeter indications for decision height, whereas CAT II and CAT III approaches use radar altimeter to determine decision height.^[6]

An ILS is required to shut down upon internal detection of a fault condition. With the increasing categories, ILS equipment is required to shut down faster, since higher categories require shorter response times. For example, a CAT I localizer must shutdown within 10 seconds of detecting a fault, but a CAT III localizer must shut down in less than 2 seconds.^[2]

Limitations and alternatives[link]

The Glideslope station for runway 09R at Hannover Airport in Germany

Due to the complexity of ILS localizer and glideslope systems, there are some limitations. Localizer systems are sensitive to obstructions in the signal broadcast area like large buildings or hangars. Glideslope systems are also limited by the terrain in front of the glideslope antennas. If terrain is sloping or uneven, reflections can create an uneven glidepath causing unwanted needle deflections. Additionally, since the ILS signals are pointed in one direction by the positioning of the arrays, ILS only supports straight-in approaches. A modified ILS called an Instrument Guidance System (IGS) is also occasionally used, the most famous example being that which was in use at one of the approach direction (13 approach) of Kai Tak Airport, Hong Kong to accommodate a non-straight approach;^[7][8] IGSes are also called Localizer Type Directional Aids in the US. Installation of ILS can also be costly due to the complexity of the antenna system and siting criteria. To avoid hazardous reflections that would affect the radiated signal, ILS critical areas and ILS sensitive areas are established. Positioning of these critical areas can prevent aircraft from using certain taxiways.^[9] This can cause additional delays in take offs due to increased hold times and increased spacing between aircraft.

In the 1980s, there was a major US & European effort to establish the Microwave Landing System (MLS), which is not similarly limited and which allows curved approaches. However, a combination of airline reluctance to invest in MLS, and the rise of Global Positioning System (GPS) has resulted in its failure to be adopted in civil aviation. The Transponder Landing System (TLS) is another alternative to an ILS that can be used where a conventional ILS will not work or is not cost-effective.

Localizer Performance with Vertical guidance (LPV) is the latest alternative to the ILS. Based on the Wide Area Augmentation System (WAAS), LPV has similar minima to ILS for appropriately equipped aircraft. As of November 2008^[update], the FAA has published more LPV approaches than Category I ILS procedures.

Another potential alternative to ILS is the Ground-Based Augmentation System (GBAS), a safety-critical system that augments the GPS Standard Positioning Service (SPS) and provides enhanced levels of service. It supports all phases of approach, landing, departure, and surface operations within the VHF coverage volume. (Local Area Augmentation System is the United States' implementation of GBAS). GBAS is expected to play a key role in modernization and in all-weather operations capability at CATI/II and III airports, terminal area navigation, missed approach guidance and surface operations. GBAS provides the capability to service the entire airport with a single frequency (VHF transmission) whereas ILS requires a separate frequency for each runway end. GBAS CAT-I is seen as a necessary step towards the more stringent operations of CAT-II/III precision approach and landing. Until recently, the technical risk of implementing GBAS prevented widespread acceptance of the technology. The FAA, along with industry, have fielded Provably Safe Prototype GBAS stations which mitigate the impact of satellite signal deformation, ionosphere differential error, ephemeris error and multipath.

History[link]

Tests of the ILS system began in 1929,^[10] and the Civil Aeronautics Administration (CAA) authorized installation of the system in 1941 at six locations. The first landing of a scheduled U.S. passenger airliner using ILS was on January 26, 1938, as a Pennsylvania Central Airlines Boeing 247-D flew from Washington, D.C., to Pittsburgh and landed in a snowstorm using only the Instrument Landing System.^[11] The first fully automatic landing using ILS occurred at Bedford Airport UK in March 1964.^[12]

Future[link]

The Microwave Landing System (MLS) introduced in the 1970s^[13] was intended to replace ILS but fell out of favour in the United States because of satellite based systems. However, it is showing a resurgence in the United Kingdom for civil aviation.^[14] ILS and MLS are the only standardized systems in Civil Aviation that meet requirements for Category III automated landings.^[15] The first Category III MLS for civil aviation was commissioned at Heathrow airport in March 2009.^[16]

The advent of the Global Positioning System (GPS) provides an alternative source of approach for aircraft. In the US, the Wide Area Augmentation System (WAAS) has been available to provide precision guidance to Category I standards since 2007, and the equivalent in Europe, the European Geostationary Navigation Overlay Service (EGNOS), is currently undergoing final trials and will be certified for safety of life applications in 2010. Other methods of augmentation are in development to provide for Category III minimums or better, such as the Local Area Augmentation System (LAAS).

The FAA Ground-Based Augmentation System (GBAS) office is currently working with the industry in anticipation of the certification of the first GBAS ground stations in Memphis, TN; Sydney, Australia; Bremen, Germany; Spain and Newark, NJ. All four countries have installed GBAS systems and are involved in technical and operational evaluation activities. The Honeywell and FAA team are working on the System Design Approval of the world's first Non-Federal U.S. approval for LAAS Category I operations; expected in first quarter 2009 and compliant with International Civil Aviation Organization (ICAO) Standards and Recommended Practices (SARPs) Category I LAAS.

Hong Kong^{[note 3]} (Chinese: 香港) is one of two special administrative regions (SARs) of the People's Republic of China (PRC), the other being Macau. A city-state^[9] situated on China's south coast and enclosed by the Pearl River Delta and South China Sea,^[10] it is known for its expansive skyline and deep natural harbour. With a land mass of 1,104 km² (426 sq mi) and a population of seven million people, Hong Kong is one of the most densely populated areas in the world.^[11] Hong Kong's population is 95 percent ethnic Chinese and 5 percent from other groups.^[12] Hong Kong's Han Chinese majority originate mainly from the cities of Guangzhou and Taishan in the neighbouring Guangdong province.^[13]

Hong Kong became a colony of the British Empire after the First Opium War (1839–42). Originally confined to Hong Kong Island, the colony's boundaries were extended in stages to the Kowloon Peninsula in 1860 and then the New Territories in 1898. It was occupied by Japan during the Pacific War, after which the British resumed control until 1997, when China resumed sovereignty.^[14][15] The region espoused minimum government intervention under the ethos of positive non-interventionism during the colonial era.^[16] The time period greatly influenced the current culture of Hong Kong, often described as "East meets West",^[17] and the educational system, which used to loosely follow the system in England^[18] until reforms implemented in 2009.^[19]

Under the principle of "one country, two systems", Hong Kong has a different political system from mainland China.^[20] Hong Kong's independent judiciary functions under the common law framework.^[21][22] Hong Kong Basic Law, its constitutional document, stipulates that Hong Kong shall have a "high degree of autonomy" in all matters except foreign relations and military defence, governs its political system.^[23][24] Although it has a burgeoning multi-party system, a small-circle electorate^{[clarification needed]} controls half of its legislature. The Chief Executive of Hong Kong, the head of government, is selected by a Selection Committee / Election Committee with 400 to 1200 members, during the first 20 years.^{[25] [26][27] [28]}

As one of the world's leading international financial centres, Hong Kong has a major capitalist service economy characterised by low taxation and free trade, and the currency, Hong Kong dollar, is the eighth most traded currency in the world.^[29] The lack of space caused demand for denser constructions, which developed the city to a centre for modern architecture and the world's most vertical city.^[30][31] Hong Kong has one of the highest per capita income in the world.^[6] The dense space also led to a highly developed transportation network with public transport travelling rate exceeding 90 percent,^[32] the highest in the world.^[33] Hong Kong has numerous high international rankings in various aspects. For instance, its economic freedom, financial and economic competitiveness, quality of life, corruption perception, Human Development Index, etc., are all ranked highly.^{[34][35][36][37][38][39][40]} According to both UN and WHO estimates, Hong Kong has the second longest life expectancy of any country in the world. ^[41][42]

Etymology[link]

The name "Hong Kong" is an approximate phonetic rendering of the pronunciation of the spoken Cantonese or Hakka name "香港", meaning "fragrant harbour".^[43] Before 1842, the name referred to a small inlet – now Aberdeen Harbour or 香港仔 hoeng¹ gong² zai² "Little Hong Kong" – between the Aberdeen Island and the south side of Hong Kong Island, which was one of the first points of contact between British sailors and local fishermen.^[44]

The reference to fragrance may refer to the harbour waters sweetened by the fresh water estuarine influx of the Pearl River, or to the incense from factories lining the coast to the north of Kowloon, which was stored around Aberdeen Harbour for export before the development of Victoria Harbour.^[43] In 1842, the Treaty of Nanking was signed, and the name Hong Kong was first recorded on official documents to encompass the entirety of the island.^[45]

History[link]

Pre-colonial[link]

Archaeological studies support a human presence in the Chek Lap Kok area from 35,000 to 39,000 years ago, and in Sai Kung Peninsula from 6,000 years ago.^[46][47][48] Wong Tei Tung and Three Fathoms Cove are the two earliest sites of human habitation in the Paleolithic period. It is believed the Three Fathom Cove was a river valley settlement and Wong Tei Tung was a lithic manufacturing site. Excavated Neolithic artefacts suggest cultural differences from the Longshan culture in northern China and settlement by the Che people prior to the migration of the Baiyue.^[49][50] Eight petroglyphs were discovered on surrounding islands, which dated to the Shang Dynasty in China.^[51]

In 214 BC, Qin Shi Huang, the first emperor of China, conquered the Baiyue tribes in Jiaozhi (modern Liangguang region) and incorporated the territory into imperial China for the first time. Modern Hong Kong is located in Nanhai commandery (modern Nanhai District) and near the ancient capital city Pun Yue.^[52][53][54] The area was consolidated under the kingdom of Nanyue, founded by general Zhao Tuo in 204 BC after the Qin Dynasty collapsed.^[55] When the kingdom was conquered by Emperor Wu of Han in 111 BC, the land was assigned to the Jiaozhi commandery under the Han Dynasty. Archaeological evidence indicates the population increased and early salt production flourished in this time period. Lei Cheng Uk Han Tomb in the Kowloon Peninsula is believed to have been built during the Han Dynasty.^[56]

During the Tang Dynasty period, the Guangdong region flourished as a regional trading center. In 736, Emperor Xuanzong of Tang established a military town in Tuen Mun to defend the coastal area in the region.^[57] The first village school, Li Ying College, was established around 1075 in the New Territories under the Northern Song Dynasty.^[58] During the Mongol invasion in 1276, the Southern Song Dynasty court moved to Fujian, then to Lantau Island and later to Sung Wong Toi (modern Kowloon City), but the child Emperor Bing of Song committed suicide by drowning with his officials after being defeated in the Battle of Yamen. Hau Wong, an official of the emperor is still worshipped in Hong Kong today.^[59]

The earliest recorded European visitor was Jorge Álvares, a Portuguese explorer who arrived in 1513.^[60][61] After establishing settlements in the region, Portuguese merchants began trading in southern China. At the same time, they invaded and built up military fortifications in Tuen Mun. Military clashes between China and Portugal led to the expulsion of the Portuguese. In the mid-16th century, the Haijin order banned maritime activities and prevented contact with foreigners; it also restricted local sea activity.^[59] In 1661–69, the territory was affected by the Great Clearance ordered by Kangxi Emperor, which required the evacuation of the coastal areas of Guangdong. It is recorded that about 16,000 persons from Xin'an County were driven inland, and 1,648 of those who left are said to have returned when the evacuation was rescinded in 1669.^[62] What is now the territory of Hong Kong became largely wasteland during the ban.^[63] In 1685, Kangxi became the first emperor to open limited trading with foreigners, which started with the Canton territory. He also imposed strict terms for trades such as requiring foreign traders to live in restricted areas, staying only for the trading seasons, banning firearms, and trading with silver only.^[64] The East India Company made the first sea venture to China in 1699, and the region's trade with British merchants developed rapidly soon after. In 1711, the company established its first trading post in Canton. By 1773, the British reached a landmark 1,000 chests of opium in Canton with China consuming 2,000 chests annually by 1799.^[64]

View of Hong Kong Island from Kowloon (published 1843)

In 1839, the refusal by Qing Dynasty authorities to import opium resulted in the First Opium War between China and Britain. Hong Kong Island was occupied by British forces on 20 January 1841 and was initially ceded under the Convention of Chuenpee as part of a ceasefire agreement between Captain Charles Elliot and Governor Qishan, but the agreement was never ratified due to a dispute between high ranking officials in both governments.^[65] It was not until 29 August 1842 that the island was formally ceded in perpetuity to the United Kingdom under the Treaty of Nanking. The British established a crown colony with the founding of Victoria City the following year.^[66]

Under British rule, the population of Hong Kong island had increased from 7,450 Chinese residents, mostly fishermen, in 1841 to over 115,000 Chinese and 8,754 Europeans in Hong Kong (including Kowloon) in 1870.^[67]

In 1860, after China's defeat in the Second Opium War, the Kowloon Peninsula and Stonecutter's Island were ceded in perpetuity to Britain under the Convention of Peking.

In 1894, the deadly Third Pandemic of bubonic plague spread from China to Hong Kong, causing 50,000–100,000 deaths.^[68]

In 1898, under the terms of the Convention for the Extension of Hong Kong Territory, Britain obtained a 99-year lease of Lantau Island and the adjacent northern lands, which became known as the New Territories.^[69] Hong Kong's territory has remained unchanged to the present.^[70][71]

During the first half of the 20th century, Hong Kong was a free port, serving as an entrepôt of the British Empire. The British introduced an education system based on their own model, while the local Chinese population had little contact with the European community of wealthy tai-pans settled near Victoria Peak.^[69]

Japanese invasion[link]

In conjunction with its military campaign, the Empire of Japan invaded Hong Kong on 8 December 1941.^[72] The Battle of Hong Kong ended with British and Canadian defenders surrendering control of the colony to Japan on 25 December.^[73] During the Japanese occupation of Hong Kong, civilians suffered widespread food shortages, rationing, and hyper-inflation due to forced exchange of currency for military notes. Through a policy of enforced repatriation of the unemployed to the mainland throughout the period, because of the scarcity of food, the population of Hong Kong had dwindled from 1.6 million in 1941 to 600,000 in 1945, when the United Kingdom resumed control of the colony.^[74]

Cold war era[link]

Granted by the College of Arms on 21 January 1959, the Blue Ensign colonial flag and coat of arms of Hong Kong were used by British Hong Kong during 1959–1997.

Hong Kong's population recovered quickly as a wave of migrants from China arrived for refuge from the ongoing Chinese Civil War. When the PRC was proclaimed in 1949, more migrants fled to Hong Kong for fear of persecution by the Communist Party.^[69] Many corporations in Shanghai and Guangzhou shifted their operations to Hong Kong.^[69]

In the 1950s, Hong Kong's rapid industrialization was driven by textile exports and other expanded manufacturing industries. As the population grew and labour costs remained low, living standards rose steadily. ^[75] The construction of Shek Kip Mei Estate in 1953 followed a massive slum fire, and marked the beginning of the public housing estate programme designed to cope with the huge influx of immigrants. Trade in Hong Kong accelerated even further when Shenzhen, immediately north of Hong Kong, became a special economic zone of the PRC, and Hong Kong was established as the main source of foreign investment in China.^[76] The manufacturing competitiveness gradually declined in Hong Kong due to the development of the manufacturing industry in southern China beginning in the early 1980s. By contrast, the service industry in Hong Kong experienced high rates of growth in the 1980s and 1990s after absorbing workers released from the manufacturing industry.^[77]

Development of Hong Kong Island in 1986

Throughout the British colonial era, Hong Kong was industrialized and improved in all aspects from its economy to its health care system. Many health facilities were built for its citizens, for example the Queen Elizabeth Hospital, Hong Kong, the Queen Mary Hospital, Hong Kong, the Princess Margaret Hospital, Hong Kong and the Prince of Wales Hospital. Many changes happened during this era shaped the future of Hong Kong. In the year 1983, when the United Kingdom reclassified Hong Kong from a British crown colony to a dependent territory, the governments of the United Kingdom and China were already discussing the issue of Hong Kong's sovereignty due to the impending expiry (within two decades) of the lease of the New Territories. In 1984, the Sino-British Joint Declaration – an agreement to transfer sovereignty to the People's Republic of China in 1997 – was signed.^[69] It stipulated that Hong Kong would be governed as a special administrative region, retaining its laws and a high degree of autonomy for at least 50 years after the transfer. The Hong Kong Basic Law, which is based on the English law would serve as the constitutional document after the transfer, was ratified in 1990.^[69]

Since 1997[link]

On 1 July 1997, the transfer of sovereignty from United Kingdom to the PRC occurred, officially ending 156 years of British colonial rule. Hong Kong became China's first special administrative region, and Tung Chee Hwa took office as the first Chief Executive of Hong Kong. That same year, Hong Kong suffered an economic double blow from the Asian financial crisis and the H5N1 avian influenza.^[69] In 2003, Hong Kong was gravely affected by the outbreak of severe acute respiratory syndrome (SARS).^[78][79] The World Health Organization reported 1,755 infected and 299 deaths in Hong Kong.^[80] An estimated 380 million Hong Kong dollars (US$48.9 million) in contracts were lost as a result of the epidemic.^[81]

On 10 March 2005, Tung Chee Hwa announced his resignation as Chief Executive due to "health problems".^[82] Donald Tsang, the Chief Secretary for Administration at the time, entered the 2005 election unopposed and became the second Chief Executive of Hong Kong on 21 June 2005.^[83] In 2007, Tsang won the Chief Executive election and continued his second term in office.^[84]

In 2009, Hong Kong hosted the fifth East Asian Games, in which nine national teams competed. It was the first and largest international multi-sport event ever held in the territory.^[85] Today, Hong Kong continues to serve as an important global financial centre, but faces uncertainty over its future due to the growing mainland China economy, and its relationship with the PRC government in areas such as democratic reform and universal suffrage.^[86]

Governance[link]

The Legislative Council Building in Central became the home to Legislative Council of Hong Kong in 1985.

In accordance with the Sino-British Joint Declaration, and the underlying principle of one country, two systems, Hong Kong has a "high degree of autonomy as a special administrative region in all areas except defence and foreign affairs."^{[note 4]} The declaration stipulates that the region maintain its capitalist economic system and guarantees the rights and freedoms of its people for at least 50 years beyond the 1997 handover.^{[note 5]} The guarantees over the territory's autonomy and the individual rights and freedoms are enshrined in a constitution, the Hong Kong Basic Law(formed based on the Common law of England), which outlines the system of governance of the Hong Kong Special Administrative Region, but which is subject to the interpretation of the Standing Committee of the National People's Congress (NPCSC).^[87][88]

The primary pillars of government are the Executive Council, the civil service, the Legislative Council, and the Judiciary. The Executive Council is headed by the Chief Executive who is elected by the Election Committee and then appointed by the Central People's Government.^[89][90] The civil service is a politically neutral body that implements policies and provides government services, where public servants are appointed based on meritocracy.^[26][91] The Legislative Council has 60 members, half of whom are directly elected by universal suffrage by permanent residents of Hong Kong according to five geographical constituencies. The other half, known as functional constituencies, are directly elected by a smaller electorate, which consists of corporate bodies and persons from various stipulated functional sectors. The entire council is headed by the President of the Legislative Council who serves as the speaker.^[92][93] Judges are appointed by the Chief Executive on the recommendation of an independent commission.^[21][94]

Government House is the official residence of the Chief Executive.

The implementation of the Basic Law, including how and when the universal suffrage promised therein is to be achieved, has been a major issue of political debate since the transfer of sovereignty. In 2002, the government's proposed anti-subversion bill pursuant to Article 23 of the Basic Law, which required the enactment of laws prohibiting acts of treason and subversion against the Chinese government, was met with fierce opposition, and eventually shelved.^[23][95][96] Debate between pro-Beijing groups, which tend to support the Executive branch, and the Pan-democracy camp characterises Hong Kong's political scene, with the latter supporting a faster pace of democratisation, and the principle of one man, one vote.^[97]

In 2004, the government failed to gain pan-democrat support to pass its so-called "district council model" for political reform.^[98] In 2009, the government reissued the proposals as the "Consultation Document on the Methods for Selecting the Chief Executive and for Forming the LegCo in 2012". The document proposed the enlargement of the Election Committee, Hong Kong's electoral college, from 800 members to 1,200 in 2012 and expansion of the legislature from 60 to 70 seats. The 10 new legislative seats would consist of five geographical constituency seats and five functional constituency seats, to be voted in by elected district council members from among themselves.^[99] The proposals were destined for rejection by pan-democrats once again, but a significant breakthrough occurred after the Central People's Government accepted a counter-proposal by the Democratic Party. In particular, the Pan-democracy camp was split when the proposal to directly elect five newly created functional seats was not acceptable to two constituent parties. The Democratic Party sided with the government for the first time since the handover and passed the proposals with a vote of 46–12.^[100]

Legal system and judiciary[link]

  The Court of Final Appeal in Central is the supreme court of Hong Kong.

Hong Kong's legal system is completely independent from the legal system of Mainland China. In contrast to mainland China's civil law system, Hong Kong continues to follow the English Common Law tradition established under British rule.^[101] Hong Kong's courts may refer to decisions rendered by courts of other common law jurisdictions as precedents,^[21][102] and judges from other common law jurisdictions are allowed to sit as non-permanent judges of the Court of Final Appeal.^[21][102]

Structurally, the court system consists of the Court of Final Appeal, the High Court, which is made up of the Court of Appeal and the Court of First Instance, and the District Court, which includes the Family Court.^[103] Other adjudicative bodies include the Lands Tribunal, the Magistrates' Courts, the Juvenile Court, the Coroner's Court, the Labour Tribunal, the Small Claims Tribunal, and the Obscene Articles Tribunal.^[103] Justices of the Court of Final Appeal are appointed by Hong Kong's Chief Executive.^[21][102]

The Department of Justice is responsible for handling legal matters for the government. Its responsibilities include providing legal advice, criminal prosecution, civil representation, legal and policy drafting and reform, and international legal cooperation between different jurisdictions.^[101] Apart from prosecuting criminal cases, lawyers of the Department of Justice act on behalf of the government in all civil and administrative lawsuits against the government.^[101] As protector of the public interest, the department may apply for judicial reviews and may intervene in any cases involving the greater public interest.^[104] The Basic Law protects the Department of Justice from any interference by the government when exercising its control over criminal prosecution.^[105][106]

Human rights[link]

Hong Kong 1 July march with British Hong Kong flag.

Hong Kong's Basic law is based on the English law and so in general, Hong Kong is perceived to enjoy a high level of civil liberties.^[107] The Hong Kong government generally respect the human rights of the citizens, although core issues remain.^[108] There are concerns over the freedom of assembly which is restricted by the Public Order Ordinance. The police has been occasionally accused of using heavy-handed tactics towards protestors^[109] and questions are asked towards the extensive powers of the police.^[110] As to the right of privacy, covert surveillance remains the major concern.^[111] There is a lack of protection for gay men and lesbians due to the absence of a sexual orientation discrimination law, though there are currently no laws that criminalize homosexuality per se.^[112] There are also comments regarding a lack of protection for labour rights.^[108]

Internet censorship in Hong Kong operates under different principles and regulations than under the rest of China.^[113]

Hong Kong has a unitary system of government; no local government has existed since the two municipal councils were abolished in 2000. As such there is no formal definition for its cities and towns. Administratively, Hong Kong is subdivided into 18 geographic districts, each represented by a district council which advises the government on local matters such as public facilities, community programmes, cultural activities, and environmental improvements.^[116]

There are a total of 534 district council seats, 405 of which are elected; the rest are appointed by the Chief Executive and 27 ex officio chairmen of rural committees.^[116] The Home Affairs Department communicates government policies and plans to the public through the district offices.^[117]

  The Cenotaph of Hong Kong.Constructed in 1923 and located between Statue Square and the City Hall in Central, Hong Kong,[1] commemorates the dead in the First and Second World War[2] that served in Hong Kong in the Royal Navy, British Army and Royal Air Force.

When Hong Kong was a British colony and later, a dependent territory, defence was provided by the British military under the command of the Governor of Hong Kong who was ex officio Commander-in-chief.^[118] Most of the members of the British Forces in Hong Kong were from Britain but there were locally enlisted personnel (LEP) who served as regular British Forces members in the Hong Kong Squadron of the Royal Navy as well as the Hong Kong Military Service Corps. The Royal Hong Kong Regiment a military unit part of the Hong Kong Government, trained and organised along timelines of British Territorial Army and supported by British Army personnel holding key positions. These British Army personnel, for their duration of service to the Royal Hong Kong Regiment, are seconded to the Hong Kong Government. In the post-WWII era, the majority of the regiment's members have been local citizens of Chinese descent. The Hong Kong Military Service Corps maintained its reputation for loyalty and military skill at the highest level, often outshining British and Gurkha troops based in Hong Kong. The HKMSC Shooting Team won the Team and Individual champion pistol shot a number of times at RASAAM (the Regular Army Skill at Arms Meeting) at Bisley, in the UK, and in 1992 a Training Company team representing the HQ and Depot HKMSC won the Dragon Cup for military skills (outperforming the Queen's Gurkha Signals in signalling and the British Military Hospital team in first aid); the competition was not held again.

The HKMSC reached a peak strength of 1,200 men, providing the British garrison in Hong Kong with supporting personnel. All HKMSC soldiers were basically trained in Hong Kong and from time to time attended upgrading and trade courses in the United Kingdom. HKMSC soldiers who were posted to and served with other non-HKMSC units, wore the other units' cap badge. Unit personnel were enlisted as officers and drivers in 29 Squadron, Royal Corps of Transport (RCT) based in Gun Club Hill Barracks. It provided crews for 415 Maritime Troop based on Stonecutters' Island, dog handlers in the Defence Animal Support Unit (DASU) of the Royal Army Veterinary Corps (RAVC) based in Sek Kong, officer instructors in the Royal Army Educational Corps (RAEC), officers and clerks in the Royal Army Pay Corps (RAPC), technicians in the Royal Signals (R Sigs) of the Queen's Gurkha Signals (QGS) and engineers and armourers in the Royal Electrical and Mechanical Engineers (REME). The HKMC trained physical training instructors (PTI) in the Army Physical Training Corps (APTC), medics in the Royal Army Medical Corps (RAMC) based in the British Military Hospital (BMH), military police in the Royal Military Police (RMP), helicopter support crews in 660 Squadron Army Air Corps (AAC) based at Sek Kong Airfield, cooks in the Army Catering Corps (ACC), Weapons and Supplies Storekeepers in the Royal Army Ordnance Corps (RAOC) and intelligence staff in the Intelligence Corps. They also provided interpreters, clerks, Regimental Police and light-infantry personnel in Dragon Company of the General Service Corps (GSC) headquartered in Osborn Baracks, Kowloon Tong. The HKMSC offered Hong Kong Chinese soldiers the opportunity to pursue a full career in the British Regular Army up to and including a Queen's Commissioned officer rank of the General List (HKMSC). As all members of the HKMSC were British Regular Army soldiers, they received a Regular Army Service Record Book when they left the army. Many of them had also been awarded the Long Service and Good Conduct Medal (LS&GC) after 15 years of good and loyal service. British gallantry awards, Orders, Decorations and Medal Ribbons had also been presented to some HKMSC soldiers; such as the Queen's Gallantry Medal (QGM), the British Empire Medal (BEM), Members of the Order of the British Empire (MBE) and the Officers of the Order of the British Empire (OBE).

When the PRC assumed sovereignty in 1997, the British barracks were replaced by a garrison of the People's Liberation Army, comprising ground, naval, and air forces, and under the command of the Chinese Central Military Commission.

The Hong Kong Basic Law is formed based on the Common law of England and it protects local civil affairs against interference by the garrison, and members of the garrison are subject to Hong Kong laws. The Hong Kong Government remains responsible for the maintenance of public order; however, it may ask the PRC government for help from the garrison in maintaining public order and in disaster relief. The PRC government is responsible for the costs of maintaining the garrison.^[23][119]

Geography and climate[link]

Areas of urban development and vegetation are visible in this false-colour satellite image.

Hong Kong is located on China's south coast, 60 km (37 mi) east of Macau on the opposite side of the Pearl River Delta. It is surrounded by the South China Sea on the east, south, and west, and borders the Guangdong city of Shenzhen to the north over the Shenzhen River. The territory's 1,104 km² (426 sq mi) area consists of Hong Kong Island, the Kowloon Peninsula, the New Territories, and over 200 offshore islands, of which the largest is Lantau Island. Of the total area, 1,054 km² (407 sq mi) is land and 50 km² (19 sq mi) is inland water. Hong Kong claims territorial waters to a distance of 3 nautical miles (5.6 km). Its land area makes Hong Kong the 179th largest inhabited territory in the world.^[3][10]

As much of Hong Kong's terrain is hilly to mountainous with steep slopes, less than 25% of the territory's landmass is developed, and about 40% of the remaining land area is reserved as country parks and nature reserves.^[120] Most of the territory's urban development exists on Kowloon peninsula, along the northern edge of Hong Kong Island, and in scattered settlements throughout the New Territories.^[121] The highest elevation in the territory is at Tai Mo Shan, 957 metres (3,140 ft) above sea level.^[122] Hong Kong's long and irregular coast provides it with many bays, rivers and beaches.^[123] On September 18, 2011, UNESCO listed the Hong Kong National Geopark as part of its Global Geoparks Network. Hong Kong Geopark is made up of eight Geo-Areas distributed across the Sai Kung Volcanic Rock Region and Northeast New Territories Sedimentary Rock Region.^[124]

Despite Hong Kong's reputation of being intensely urbanised, the territory has tried to promote a green environment,^[125] and recent growing public concern has prompted the severe restriction of further land reclamation from Victoria Harbour.^[126] Awareness of the environment is growing as Hong Kong suffers from increasing pollution compounded by its geography and tall buildings. Approximately 80% of the city's smog originates from other parts of the Pearl River Delta.^[127]

Though it is situated just south of the Tropic of Cancer, Hong Kong has a humid subtropical climate (Köppen Cwa). Summer is hot and humid with occasional showers and thunderstorms, and warm air coming from the southwest. Summer is when typhoons are most likely, sometimes resulting in flooding or landslides. Winters are mild and usually start sunny, becoming cloudier towards February; the occasional cold front brings strong, cooling winds from the north. The most temperate seasons are spring, which can be changeable, and autumn, which is generally sunny and dry.^[128] Hong Kong averages 1,948 hours of sunshine per year,^[129] while the highest and lowest ever recorded temperatures at the Hong Kong Observatory are 36.1 °C (97.0 °F) and 0.0 °C (32.0 °F), respectively.^[130]

Economy[link]

The International Finance Centre in Central

As one of the world's leading international financial centres, Hong Kong has a major capitalist service economy characterised by low taxation and free trade. The currency, Hong Kong dollar, is the eighth most traded currency in the world as of 2010.^[29] Hong Kong was once described by Milton Friedman as the world’s greatest experiment in laissez-faire capitalism.^[132] It maintains a highly developed capitalist economy, ranked the freest in the world by the Index of Economic Freedom every year since 1995.^{[133][134][135]} It is an important centre for international finance and trade, with one of the greatest concentrations of corporate headquarters in the Asia-Pacific region,^[136] and is known as one of the Four Asian Tigers for its high growth rates and rapid development from the 1960s to the 1990s. Between 1961 and 1997 Hong Kong's gross domestic product grew 180 times while per-capita GDP increased 87 times over.^{[137][138][139]}

The Hong Kong Stock Exchange is the seventh largest in the world, with a market capitalisation of US$2.3 trillion as of December 2009.^[140] In that year, Hong Kong raised 22 percent of worldwide initial public offering (IPO) capital, making it the largest centre of IPOs in the world ^[141] and the easiest place to raise capital.^[142] Hong Kong's currency is the Hong Kong dollar, which has been pegged to the U.S. dollar since 1983.^[143]

The Hong Kong Government has traditionally played a mostly passive role in the economy, with little by way of industrial policy and almost no import or export controls. Market forces and the private sector were allowed to determine practical development. Under the official policy of "positive non-interventionism", Hong Kong is often cited as an example of laissez-faire capitalism. Following the Second World War, Hong Kong industrialised rapidly as a manufacturing centre driven by exports, and then underwent a rapid transition to a service-based economy in the 1980s.^[144] Since then, it has grown to become a leading center for management, financial, IT, business consultation and professional services.^[142]

Hong Kong matured to become a financial centre in the 1990s, but was greatly affected by the Asian financial crisis in 1998, and again in 2003 by the SARS outbreak. A revival of external and domestic demand has led to a strong recovery, as cost decreases strengthened the competitiveness of Hong Kong exports and a long deflationary period ended.^[145][146] Government intervention, initiated by the later colonial governments and continued since 1997, has steadily increased, with the introduction of export credit guarantees, a compulsory pension scheme, a minimum wage, anti-discrimination laws, and a state mortgage backer.^[132]

The territory has little arable land and few natural resources, so it imports most of its food and raw materials. Agricultural activity—relatively unimportant to Hong Kong’s economy and contributing just 0.1% of its GDP—primarily consists of growing premium food and flower varieties.^[142] Hong Kong is the world's eleventh largest trading entity,^[147] with the total value of imports and exports exceeding its gross domestic product. It is the world's largest re-export centre.^[148] Much of Hong Kong's exports consist of re-exports,^[149] which are products made outside of the territory, especially in mainland China, and distributed via Hong Kong. Its physical location has allowed the city to establish a transportation and logistics infrastructure that includes the world’s second busiest container port and the world’s busiest airport for international cargo.^[142] Even before the transfer of sovereignty, Hong Kong had established extensive trade and investment ties with the mainland, which now enable it to serve as a point of entry for investment flowing into the mainland. At the end of 2007, there were 3.46 million people employed full-time, with the unemployment rate averaging 4.1% for the fourth straight year of decline.^[150] Hong Kong's economy is dominated by the service sector, which accounts for over 90% of its GDP, while industry constitutes 9%. Inflation was at 2.5% in 2007.^[151] Hong Kong's largest export markets are mainland China, the United States, and Japan.^[3]

As of 2010, Hong Kong is the eighth most expensive city for expatriates, falling from fifth position in the previous year.^[152] Hong Kong is ranked fourth in terms of the highest percentage of millionaire households, behind Switzerland, Qatar, and Singapore with 8.5 percent of all households owning at least one million US dollars.^[153] In 2011, Hong Kong was ranked second in the Ease of Doing Business Index, behind Singapore.^[154] General principle No. 5 of the Basic Law of the SAR suggests that the CPC expects that it shall have brought the economic system of the Mainland and Hong Kong into harmony by 2047, by which time the Chinese economy is predicted by Businessweek to have been the largest by any measure of GDP for decades.^[155]

Demographics[link]

The territory's population is 7.03 million. In 2009, Hong Kong had a birth rate of 11.7 per 1,000 population and a fertility rate of 1,032 children per 1,000 women.^[156] Residents from mainland China do not have the right of abode in Hong Kong, nor are they allowed to enter the territory freely.^[95] However, the influx of immigrants from mainland China, approximating 45,000 per year, is a significant contributor to its population growth – a daily quota of 150 Mainland Chinese with family ties in Hong Kong are granted a "one way permit".^[157] Life expectancy in Hong Kong is 79.16 years for males and 84.79 years for females as of 2009, making it one of the highest life expectancies in the world.^[3]

About 95% of the people of Hong Kong are of Chinese descent,^[12] the majority of whom are Taishanese, Chiu Chow, other Cantonese people, and Hakka. Hong Kong's Han majority originate mainly from the Guangzhou and Taishan regions in Guangdong province.^[13] The remaining 5% of the population is composed of non-ethnic Chinese.^[12] There is a South Asian population of Indians, Pakistanis and Nepalese; some Vietnamese refugees have become permanent residents of Hong Kong. There are also Europeans (mostly British), Americans, Canadians, Japanese, and Koreans working in the city's commercial and financial sector.^{[note 6]} In 2008, there were an estimate of 252,500 foreign domestic helpers from Indonesia and the Philippines working in Hong Kong.^[159]

Hong Kong's de facto official language is Cantonese, a Chinese language originating from Guangdong province to the north of Hong Kong.^[160] English is also an official language, and according to a 1996 by-census is spoken by 3.1 percent of the population as an everyday language and by 34.9 percent of the population as a second language.^[161] Signs displaying both Chinese and English are common throughout the territory. Since the 1997 handover, an increase in immigrants from mainland China and greater integration with the mainland economy have brought an increasing number of Mandarin speakers to Hong Kong.^[162]

A majority of residents of Hong Kong would claim no religious affiliation, professing a form of agnosticism or atheism.^[163] According to the U.S Department of State only 43 percent of the population practices some form of religion.^[164] Some figures put it higher, according to a Gallup poll, 64% of Hong Kong residents do not believe in any religion,^[165][166] and possibly 80% of Hong Kong claim no religion.^[167] In Hong Kong teaching evolution won out in curriculum dispute about whether to teach other explanations, and that creationism and intelligent design will form no part of the senior secondary biology curriculum^{[168] [169]}

Hong Kong enjoys a high degree of religious freedom, guaranteed by the Basic Law. Hong Kong's main religions are Buddhism, Taoism, and Confucianism; a local religious scholar in contact with major denominations estimates there are approximately 1.5 million Buddhists and Taoists.^[164] A Christian community of around 600,000 forms about 8% of the total population;^[170][171] it is nearly equally divided between Catholics and Protestants, although smaller Christian communities exist, including the Latter-Day Saints^[172] and Jehovah's Witnesses.^[173] The Anglican and Roman Catholic churches each freely appoint their own bishops, unlike in mainland China. There are also Sikh, Muslim, Jewish, Hindu and Bahá'í communities.^[170] The practice of Falun Gong is tolerated.^[174]

Statistically Hong Kong's income gap is the greatest in Asia Pacific. According to a report by the United Nations Human Settlements Programme in 2008, Hong Kong's Gini coefficient, at 0.53, was the highest in Asia and "relatively high by international standards".^[175][176] However, the government has stressed that income disparity does not equate to worsening of the poverty situation, and that the Gini coefficient is not strictly comparable between regions. The government has named economic restructuring, changes in household sizes, and the increase of high-income jobs as factors that have skewed the Gini coefficient.^{[177][178][179]}

Education[link]

A view over the University of Hong Kong

Hong Kong's education system used to roughly follow the system in England,^[18] although international systems exist. The government maintains a policy of "mother tongue instruction" (Chinese: 母語教學) in which the medium of instruction is Cantonese,^[180] with written Chinese and English. In secondary schools, 'biliterate and trilingual' proficiency is emphasised, and Mandarin-language education has been increasing.^[181] The Programme for International Student Assessment ranked Hong Kong's education system as the second best in the world.^[182] Hong Kong's public schools are operated by the Education Bureau. The system features a non-compulsory three-year kindergarten, followed by a compulsory six-year primary education, a compulsory three-year junior secondary education, a non-compulsory two-year senior secondary education leading to the Hong Kong Certificate of Education Examinations and a two-year matriculation course leading to the Hong Kong Advanced Level Examinations.^[183] The New Senior Secondary academic structure and curriculum was implemented in September 2009, which provides for all students to receive three years of compulsory junior and three years of compulsory senior secondary education.^[19][184] Under the new curriculum, there is only one public examination, namely the Hong Kong Diploma of Secondary Education.^[185]

Most comprehensive schools in Hong Kong fall under three categories: the rarer public schools; the more common subsidised schools, including government aids-and-grant schools; and private schools, often run by Christian organisations and having admissions based on academic merit rather than on financial resources. Outside this system are the schools under the Direct Subsidy Scheme and private international schools.^[184]

There are nine public universities in Hong Kong, and a number of private higher institutions, offering various bachelor's, master's, and doctoral degrees, other higher diplomas, and associate degree courses.The University of Hong Kong, the oldest institution of tertiary education in the territory, was described by Quacquarelli Symonds as a "world-class comprehensive research university"^[186] and was ranked 24th on the 2009 THES - QS World University Rankings,^[187] making it first in Asia.^[188] The Hong Kong University of Science & Technology was ranked 35th in the world in 2009 and ranked second in Asia for 2010. The Chinese University of Hong Kong was ranked 46th in the world in 2009 and ranked fourth in Asia for 2010.^[188] Based on the 2011 rankings published by career and education network QS, three of the top five Asian universities are in Hong Kong. They are the Hong Kong University of Science and Technology, the University of Hong Kong and Chinese University of Hong kong as first, second and fifth rank, respectively.^[189]

Healthcare[link]

This unreferenced section requires citations to ensure verifiability.

There are 13 private hospitals and more than 50 public hospitals in Hong Kong. Among the widest range of healthcare services throughout the globe are on offer, and some of the SAR's private hospitals are rightly considered to be among the very best of their type in the world.

There are two medical schools in the SAR, one based at the Chinese University of Hong Kong and the other at Hong Kong University. Both have strong links with public sector hospitals.

With respect to postgraduate education, traditionally many doctors in Hong Kong have looked overseas for further training, and many took British Royal College exams such as the MRCP(UK) and the MRCS(UK). However, Hong Kong has been developing its own postgraduate medical institutions, in particular the Hong Kong Academy of Medicine, and this is gradually taking over the responsibility for all postgraduate medical training in the SAR.

There are also strong public health systems in Hong Kong, and the Centre for Health Protection, founded after the SARS outbreak of 2003, is particularly worthy of mention.

By 2011, however, there have been growing concerns that mothers-to-be from Mainland China, in a bid to obtain the right of abode in Hong Kong and the benefits that come with it, have saturated the neonatal wards of the city's hospitals, both public and private sectors, which has led to outcries and protests from local pregnant women for the government to remedy the issue, as they have found difficulty securing a bed space for giving birth and arrange routine check-ups. Other concerns in the decade of 2001-2010 relate to the workload medical staff experience; and medical errors and mishaps, which are frequently highlighted in local news.

Culture[link]

City lights of Kowloon

Hong Kong is frequently described as a place where "East meets West", reflecting the culture's mix of the territory's Chinese roots with influences from its time as a British colony.^[17] Hong Kong balances a modernised way of life with traditional Chinese practices. Concepts like feng shui are taken very seriously, with expensive construction projects often hiring expert consultants, and are often believed to make or break a business.^[190] Other objects like Ba gua mirrors are still regularly used to deflect evil spirits,^[191] and buildings often lack any floor number that has a 4 in it,^[192] due to its similarity to the word for "die" in Cantonese.^[193] The fusion of east and west also characterises Hong Kong's cuisine, where dim sum, hot pot, and fast food restaurants coexist with haute cuisine.^[194]

Hong Kong is a recognised global centre of trade, and calls itself an "entertainment hub".^[195] Its martial arts film genre gained a high level of popularity in the late 1960s and 1970s. Several Hollywood performers, notable actors and martial artists have originated from Hong Kong cinema, notably Bruce Lee, Jackie Chan, Chow Yun-fat, Michelle Yeoh, Maggie Cheung and Jet Li. A number of Hong Kong film-makers have achieved widespread fame in Hollywood, such as John Woo, Wong Kar-wai, and Stephen Chow.^[195] Homegrown films such as Chungking Express, Infernal Affairs, Shaolin Soccer, Rumble in the Bronx, In the Mood for Love and Echoes of the Rainbow have gained international recognition. Hong Kong is the centre for Cantopop music, which draws its influence from other forms of Chinese music and Western genres, and has a multinational fanbase.^[196]

The Hong Kong government supports cultural institutions such as the Hong Kong Heritage Museum, the Hong Kong Museum of Art, the Hong Kong Academy for Performing Arts, and the Hong Kong Philharmonic Orchestra. The government's Leisure and Cultural Services Department subsidises and sponsors international performers brought to Hong Kong. Many international cultural activities are organised by the government, consulates, and privately.^[197][198]

Hong Kong has two licensed terrestrial broadcasters – ATV and TVB. There are three local and a number of foreign suppliers of cable and satellite services.^[199] The production of Hong Kong's soap dramas, comedy series, and variety shows reach audiences throughout the Chinese-speaking world. Magazine and newspaper publishers in Hong Kong distribute and print in both Chinese and English, with a focus on sensationalism and celebrity gossip.^[200] The media in Hong Kong is relatively free from official interference compared to mainland China, although the Far Eastern Economic Review points to signs of self-censorship by journals whose owners have close ties to or business interests in the People's Republic of China and states that even Western media outlets are not immune to growing Chinese economic power.^[201]

Hong Kong offers wide recreational and competitive sport opportunities despite its limited land area. It sends delegates to international competitions such as the Olympic Games and Asian Games, and played host to the equestrian events during the 2008 Summer Olympics.^[202] There are major multipurpose venues like Hong Kong Coliseum and MacPherson Stadium. Hong Kong's steep terrain and extensive trail network with expansive views attracts hikers, and its rugged coastline provides many beaches for swimming.^[203]

Architecture[link]

According to Emporis, there are 7,650 skyscrapers in Hong Kong, which puts the city at the top of world rankings.^[204] It has more buildings higher than 500ft (or 150m) than any other city. The high density and tall skyline of Hong Kong's urban area is due to a lack of available sprawl space, with the average distance from the harbour front to the steep hills of Hong Kong Island at 1.3 km (0.81 mi),^[205] much of it reclaimed land. This lack of space causes demand for dense, high-rise offices and housing. Thirty-six of the world's 100 tallest residential buildings are in Hong Kong.^[206] More people in Hong Kong live or work above the 14th floor than anywhere else on Earth, making it the world's most vertical city.^[30][31]

As a result of the lack of space and demand for construction, few older buildings remain, and the city is becoming a centre for modern architecture. The International Commerce Centre (ICC), at 484 m (1,588 ft) high, is the tallest building in Hong Kong and the third tallest in the world, by height to roof measurement.^[207] The tallest building prior to the ICC is Two International Finance Centre, at 415 m (1,362 ft) high.^[208] Other recognisable skyline features include the HSBC Headquarters Building, the triangular-topped Central Plaza with its pyramid-shaped spire, The Center with its night-time multi-coloured neon light show; A Symphony of Lights and I. M. Pei's Bank of China Tower with its sharp, angular façade. According to the Emporis website, the city skyline has the biggest visual impact of all world cities.^[209] Also, Hong Kong's skyline is often regarded to be the best in the world,^[210] with the surrounding mountains and Victoria Harbour complementing the skyscrapers.^[211][212] Most of the oldest remaining historic structures, including the Tsim Sha Tsui Clock Tower, the Central Police Station, and the remains of Kowloon Walled City were constructed during the 19th and early 20th centuries.^{[213][214][215]}

There are many development plans in place, including the construction of new government buildings,^[216] waterfront redevelopment in Central,^[217] and a series of projects in West Kowloon.^[218] More high-rise development is set to take place on the other side of Victoria Harbour in Kowloon, as the 1998 closure of the nearby Kai Tak Airport lifted strict height restrictions.^[219]

Transport[link]

Hong Kong's transportation network is highly developed. Over 90% of daily travels (11 million) are on public transport,^[32] the highest such percentage in the world.^[33] Payment can be made using the Octopus card, a stored value system introduced by the Mass Transit Railway (MTR), which is widely accepted on railways, buses and ferries, and accepted like cash at other outlets.^[220][221]

The city's main railway company (KCRC) was merged with the urban mass transit operator (MTR) in 2007, creating a comprehensive rail network for the whole territory (also called MTR).^[222] This MTR rapid transit system has 152 stations, which serve 3.4 million people a day.^[223] Hong Kong Tramways, which has served the territory since 1904, covers the northern parts of Hong Kong Island.^[224]

Hong Kong's bus service is franchised and run by private operators. Five privately owned companies provide franchised bus service across the territory, together operating more than 700 routes. The two largest, Kowloon Motor Bus provides 402 routes in Kowloon and New Territories; Citybus operates 154 routes on Hong Kong Island; both run cross-harbour services. Double-decker buses were introduced to Hong Kong in 1949, and are now almost exclusively used; single-decker buses remain in use for routes with lower demand or roads with lower load capacity. Public light buses serve most parts of Hong Kong, particularly areas where standard bus lines cannot reach or do not reach as frequently, quickly, or directly.^[225]

The Hong Kong-Kowloon Ferry

The Star Ferry service, founded in 1888, operates four lines across Victoria Harbour and provides scenic views of Hong Kong's skyline for its 53,000 daily passengers.^[226] It acquired iconic status following its use as a setting on The World of Suzie Wong. Travel writer Ryan Levitt considered the main Tsim Sha Tsui to Central crossing one of the most picturesque in the world.^[227] Other ferry services are provided by operators serving outlying islands, new towns, Macau, and cities in mainland China. Hong Kong is famous for its junks traversing the harbour, and small kai-to ferries that serve remote coastal settlements.^[228][229] The Port of Hong Kong is a busy deepwater port, specialising in container shipping.^[230]

The Peak Tram of Hong Kong

Hong Kong Island's steep, hilly terrain was initially served by sedan chairs.^[231] The Peak Tram, the first public transport system in Hong Kong, has provided vertical rail transport between Central and Victoria Peak since 1888.^[232] In Central and Western district, there is an extensive system of escalators and moving pavements, including the longest outdoor covered escalator system in the world, the Mid-Levels escalator.^[233]

Hong Kong International Airport is a leading air passenger gateway and logistics hub in Asia and one of the world's busiest airports in terms of international passenger and cargo movement, serving more than 47 million passengers and handling 3.74 million tonnes (4.12 million tons) of cargo in 2007.^[234] It replaced the overcrowded Kai Tak Airport in Kowloon in 1998, and has been rated as the world's best airport in a number of surveys.^[235] Over 85 airlines operate at the two-terminal airport and it is the primary hub of Cathay Pacific, Dragonair, Air Hong Kong, Hong Kong Airlines, and Hong Kong Express.^[234][236]
