An urban area is a location characterized by high human population density and vast human-built features in comparison to the areas surrounding it. Urban areas may be cities, towns or conurbations, but the term is not commonly extended to rural areas such as villages and hamlets.
The world's urban population in 1950 of just 746 million has soared in the decades since. In 2009, the number of people living in urban areas (3.42 billion) surpassed the number living in rural areas (3.41 billion) and since then the world has become more urban than rural. This was the first time that the majority of the world's population lived in a city. In 2014 there were 7.25 billion people living on the planet, of which the global urban population comprised 3.9 billion. The Population Division of the United Nations Department of Economic and Social Affairs at that time predicted the urban population would grow to 6.4 billion by 2050, with 37% of that growth to come from three countries: China, India and Nigeria.
This is a list of contiguous urban areas of the world ordered according to population as of 2014/2015. The figures here have been taken from Demographia's "World Urban Areas" study.
Demographia defines an urban area (urbanized area agglomeration or urban centre) as a continuously built up land mass of urban development that is within a labor market (i.e. metropolitan area or metropolitan region), without regard for administrative boundaries (i.e. municipality, city or commune). Except in Australia, the authorities use a minimum urban density definition of 400 persons per square kilometer (or the nearly identical 1,000 per square mile in the United States). Demographia uses maps, satellite photographs to estimate continuous urbanization. Demographia also uses small area population data, where available, to match population estimates to urbanized land area. National census authority data are presented in Australia, Canada, France, Norway, Sweden, the United Kingdom and the United States. Census of India urban agglomerations are not used in some cases because the geographical size of constituent units (municipalities) often includes large rural (non-urban) areas.
A list is any enumeration of a set of items. List or lists may also refer to:
Urban means "related to cities." It may refer to:
A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.
In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area. The probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. Under normal conditions, breeding is substantially more common within the area than across the border.
In sociology, population refers to a collection of humans. Demography is a social science which entails the statistical study of human populations. This article refers mainly to human population.
In population genetics a sexual population is a set of organisms in which any pair of members can breed together. This means that they can regularly exchange gametes to produce normally-fertile offspring, and such a breeding group is also known therefore as a gamodeme. This also implies that all members belong to the same of species, such as humans. If the gamodeme is very large (theoretically, approaching infinity), and all gene alleles are uniformly distributed by the gametes within it, the gamodeme is said to be panmictic. Under this state, allele (gamete) frequencies can be converted to genotype (zygote) frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics.

Data in this video comes from Global Insight's report to the United States Conference of Mayors and The Council on Metro Economies and the New American City. According to the report, economic growth in US metropolitan areas in the coming decades will test their infrastructures. Employment and population are two major drivers for congestion-related costs. Over the next decade, the 15 metros with the largest increases in employment will be adding at least a quarter of a million jobs each. The strain on current transportation infrastructure cannot be understated as 12 of these 15 metros already rank among the 15 highest in congestion per commuter. In addition to employment growth, which will put further strain on rush hour commutes, general population gains will also contribute to congestio...

Largest Cities Proper by Population This is a list of the most populous cities in the world defined according to a concept of city proper (an urban locality without its suburbs). "World Urbanization Prospects", a United Nations publication, defines the population of a city proper as "the population living within the administrative boundaries of a city." The book continues to say that "city proper as defined by administrative boundaries may not include suburban areas where an important proportion of the population working or studying in the city lives." City proper is a "locality with legally fixed boundaries and an administratively recognized urban status that is usually characterized by some form of local government", or the area within the city limits. City proper is not limited to a cit...

Our native steelhead and salmon are part of a magnificent natural heritage in the central coast of California. Unfortunately, urbanization and drought have significantly impacted the health of our watersheds and native fish have paid the price. Coho salmon in the Central California Coast have declined more than 95 percent from historic population levels, and are listed species as an endangered species under the U.S. Endangered Species Act. Just a half hour from the SF Bay Area's urban centers, the Lagunitas Creek watershed is one of the most important waterways left for wild coho salmon, supporting 10 to 20 percent of all Central Coast coho salmon surviving today. In this episode, you'll get a get a glimpse into frontline efforts to restore healthy, self-sustaining populations of Californ...
