The United States Census Bureau (officially the Bureau of the Census, as defined in Title 13 U.S.C. § 11) is the government agency that is responsible for the United States Census. It also gathers other national demographic and economic data. As part of the United States Department of Commerce, the Census Bureau serves as a leading source of data about America's people and economy.^[1]

The most visible role of the Census Bureau is to perform the official decennial (every 10 years) count of people living in the U.S. The most important result is the reallocation of the number of seats each state is allowed in the House of Representatives,^[1] but the results also affect a range of government programs received by each state. The agency director is a political appointee selected by the President of the United States.

Legal mandate[link]

The Constitution of the United States (Article I, section II) directs that the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College. The Census Bureau now conducts a full population count every 10 years in years ending with a 0 (zero) and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population estimates and projections.^[2]

In addition, Census data directly affects how more than $400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health, education, transportation and much more. The Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, and economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.

The Census Bureau also conducts surveys on behalf of various federal government and local government agencies on topics such as employment, crime, health, consumer expenditures, and housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial (10-year) population counts. The Census Bureau also conducts economic surveys of manufacturing, retail, service, and other establishments and of domestic governments.

From 1790 to 1840, the census was taken by marshals of the judicial districts.^[3] The Census Act of 1840 established a central office^[4] which became known as the Census Office. Several acts followed that revised and authorized new censuses, typically at the 10-year intervals. In 1902 the temporary Census Office was moved under the Department of Interior, and in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor. The department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department.^[5]

An act in 1920 changed the date and authorized manufacturing censuses every 2 years and agriculture censuses every 10 years.^[6] In 1929, a bill was passed mandating that the House of Representatives be reapportioned based on the results of the 1930 Census.^[6] In 1954, various acts were codified into Title 13 of the US Code.^[7]

By law the Census Bureau must count everyone and submit state population totals to the U.S. President by December 31, 2010. States within the Union receive the results in the spring of the following year.

Uses of census data[link]

Many federal, state, local and tribal governments use census data to:

• Decide the location of new housing and public facilities,
• Examine the demographic characteristics of communities, states, and the USA,
• Plan transportation systems and roadways,
• Determine quotas and creation of police and fire precincts, and
• Create localized areas for elections, schools, utilities, etc.

Businesses[link]

Business also has many uses for census data, as listed;

• Forecast future product demand,
• Determine site locations for expansion/new business,
• Determine future need for nursing homes, day care centers, hospitals, etc.,
• Clarify if they are employing a representative workforce.^[1]

Data stewardship[link]

The United States Census Bureau is committed to confidentiality, and guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U.S. Code establishes penalties for the disclosure of this information. All Census employees must sign a sworn affidavit of non-disclosure prior to employment.

The Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government and law enforcement agencies such as the IRS or the FBI or Interpol. "Providing quality data, for public good—while respecting individual privacy and, at the same time, protecting confidentiality—is the Census Bureau's core responsibility", "Keeping the public's trust is critical to the Census's ability to carry out the mission as the leading source of quality data about the Nation's people and economy."^[8] Only after 72 years does the information collected become available to other agencies or the general public.

In 1918, the Census Bureau released individual information regarding several hundred young men to the Justice Department and Selective Service system for the purpose of prosecutions for draft evasion.^[9][10] During World War II, the United States Census Bureau assisted the government's Japanese American internment efforts by providing confidential neighborhood information on Japanese-Americans. The Bureau's role was denied for decades but was finally proven in 2007.^[11][12]

Organizational structure[link]

US Census Bureau Regions, centered on and divided by its twelve regional offices.

Since 1903, the official census-taking agency of the United States government has been the Bureau of the Census. The Census Bureau is headed by a Director, assisted by a Deputy Director and an Executive Staff composed of the associate directors. In April 2009, President Barack Obama nominated Robert M. Groves to head the Census Bureau.

Census headquarters in Suitland, Maryland

The Census Bureau has had headquarters in Suitland, Maryland, since 1942. A new headquarters complex was completed in 2007 and supports over 4,000 employees.^[13] The Bureau operates regional offices in 12 cities: Boston, New York City, Philadelphia, Detroit, Chicago, Kansas City, Seattle, Charlotte, Atlanta, Dallas, Denver, and Los Angeles. The National Processing Center is located in Jeffersonville, Indiana. Additional temporary processing facilities are used to facilitate the decennial census, which employs more than a million people. The cost of the 2000 Census was $4.5 billion. During the years just prior to the decennial census, parallel census offices, known as "Regional Census Centers" are opened in the field office cities. The decennial operations are carried out from these facilities. The Regional Census Centers oversee the openings and closings of smaller "Local Census Offices" within their collection jurisdictions. The estimated cost of the 2010 Census is $14.7 billion.

The Census Bureau also runs the Census Information Center cooperative program that involves 58 "national, regional, and local non-profit organizations." The CIC program aims to represent the interests of underserved communities.^[14]

Census regions and divisions[link]

The United States Census Bureau has four official regions, with nine official divisions.

Computer equipment[link]

A card puncher, part of the tabulation system used to compile the thousands of facts gathered by the Bureau. Holes are punched in the card according to a prearranged code transferring the facts from the census questionnaire into statistics.

The 1890 census was the first to use the electric tabulating machines invented by Herman Hollerith.^[15][16] For 1890-1940 details, see Truesdell, Leon E. (1965). The Development of Punch Card Tabulation in the Bureau of the Census, 1890-1940: With outlines of actual tabulation programs. US GPO.  In 1946, knowing of the Bureau's funding of Hollerith and, later, Powers, John Mauchly approached the Bureau about early funding for UNIVAC development.^[17] A UNIVAC I computer was accepted by the Bureau in 1951.^[18]

In order to reduce paper usage and reduce payroll expenses, 500,000 handheld computers (HHC's) were used for the first time in 2009 during the address canvassing portion of the 2010 Decennial Census Project. Projected savings are estimated to be over $1 billion.^[19] The further implementation of advanced computer systems in the planning for the 2020 census provides major challenges for an upgrade in the technological broadening of census protocol.

Ongoing surveys[link]

A survey is a method of collecting and analyzing social, economic, and geographic data. It provides information about the conditions of the United States, states, and counties. Throughout the decade between censuses, the bureau is conducts surveys to produce a general view and comprehensive study of the United States' social and economic conditions.

Staff from the Current Surveys Program conduct ongoing and special surveys about people and their characteristics. A network of professional field representatives gathers information from a sample of households, responding to questions about employment, consumer expenditures, health, housing, and other topics. Surveys conducted between decades:

• American Community Survey
• Consumer Expenditure Survey
• Census of Governments
• Current Population Survey
• Economic Census
• National Hospital Discharge Survey
• National Health Interview Survey
• National Hospital Ambulatory Medical Care Survey
• National Crime Victimization Survey
• National Ambulatory Medical Care Survey (NAMCS)

The Bureau of the Census is part of the United States Department of Commerce.

The United States Census is a decennial census mandated by the United States Constitution.^[1] The population is enumerated every 10 years and the results are used to allocate Congressional seats (congressional apportionment), electoral votes, and government program funding.^[2] The United States Census Bureau (officially the Bureau of the Census, as defined in Title 13 U.S.C. § 11) is the government agency that is responsible for the United States Census.

The census is performed by the United States Census Bureau. The first census after the American Revolution was taken in 1790, under Secretary of State Thomas Jefferson; there have been 22 federal censuses since that time.^[2] The current national census was held in 2010 and the next census is scheduled for 2020. For years between the decennial censuses, the Census Bureau issues estimates made using surveys and statistical models, in particular, the American Community Survey.

Title 13 of the United States Code governs how the Census is conducted and how its data is handled. Information is confidential as per 13 U.S.C. § 9. Refusing or neglecting to answer the census is punishable by fines of $100, for a property or business agent to fail to provide correct names for the census is punishable by fines of $500, and for a business agent to provide false answers for the census is punishable by fines of $10,000, pursuant to 13 U.S.C. § 221-224.

The United States Census is a population census, which is distinct from the U.S. Census of Agriculture, which is no longer the responsibility of the Census Bureau. It is also distinct from local censuses conduced by some states or local jurisdictions.

Procedure[link]

Decennial U.S. Census figures are based on actual counts of persons dwelling in U.S. residential structures. They include citizens, non-citizen legal residents, non-citizen long-term visitors and illegal immigrants. The Census Bureau bases its decision about whom to count on the concept of usual residence. Usual residence, a principle established by the Census Act of 1790, is defined as the place a person lives and sleeps most of the time. The Census Bureau uses special procedures to ensure that those without conventional housing are counted; however, data from these operations are not considered as accurate as data obtained from traditional procedures.^[3]

The Census also employs the practice of hot deck imputation to assign data to housing units where occupation status is unknown. This practice has effects across many areas, but is seen by some as controversial because it may increase representation for reliably Democratic districts. However, the practice was ruled constitutional by the U.S. Supreme Court in Utah v. Evans.

The practice of including non-citizens in the official census figures is controversial because the census is used for the apportionment of seats in the House of Representatives, and derived from that, of electors to the Electoral College. Groups like the Prison Policy Initiative assert that the census practice of counting prisoners as residents of prisons, not their pre-incarceration addresses, leads to misleading information about racial demographics and population numbers.^[4] Certain American citizens living overseas are specifically excluded from being counted in the census even though they may vote. Only Americans living abroad who are "Federal employees (military and civilian) and their dependents living overseas with them" are counted. "Private U.S. citizens living abroad who are not affiliated with the Federal government (either as employees or their dependents) will not be included in the overseas counts. These overseas counts are used solely for reapportioning seats in the U. S. House of Representatives." ^[5]

History[link]

Censuses had been taken prior to the Constitution's ratification; in the early 17th century, a census was taken in Virginia, and people were counted in nearly all of the British colonies that became the United States.

Throughout the years, the country's needs and interests became more complex. This meant that statistics were needed to help people understand what was happening and have a basis for planning. The content of the decennial census changed accordingly. In 1810, the first inquiry on manufactures, quantity and value of products occurred; in 1840, inquiries on fisheries were added; and in 1850, the census included inquiries on social issues, such as taxation, churches, pauperism, and crime. The censuses also spread geographically, to new states and territories added to the Union, as well as to other areas under U.S. sovereignty or jurisdiction. There were so many more inquiries of all kinds in the census of 1880 that almost a full decade was needed to publish all the results. In response to this, the census was mechanized in 1890, with tabulating machines made by Herman Hollerith. This reduced the processing time to two and a half years.^[6]

For the first six censuses (1790–1840), enumerators recorded only the names of the heads of household and a general demographic accounting of the remaining members of the household. Beginning in 1850, all members of the household were named on the census. The first slave schedules were also completed in 1850, with the second (and last) in 1860. Censuses of the late 19th century also included agricultural and industrial schedules to gauge the productivity of the nation's economy. Mortality schedules (taken between 1850 and 1880) captured a snapshot of life spans and causes of death throughout the country.

The first nine censuses (1790–1870) were not managed by the Executive branch, but by the Judicial branch. The United States federal court districts assigned U.S. marshals, who hired assistant marshals to conduct the actual enumeration. The census enumerators were typically from the village or neighborhood and often knew the residents. Before enabling self-identification on the censuses, the US Census Bureau relied on local people to have some knowledge of residents. Racial classification was made by the census enumerator in these decades not by the individual.

Respondent confidentiality[link]

The principal purpose of the census is to divide the house seats by population. In addition, collected data is used in aggregate for statistical purposes.^[9] Replies are obtained from individuals and establishments only to enable the compilation of such general statistics. The confidentiality of these replies is very important. By law, no one — neither the census takers nor any other Census Bureau employee — is permitted to reveal identifiable information about any person, household, or business. Without such protections, those living illegally in the United States or hiding from the government would be deterred from submitting census data.

Historical FBI use of data[link]

Under the administration of President Franklin D. Roosevelt the Federal Bureau of Investigation (FBI), using primarily census records, compiled (1939–1941) the Custodial Detention Index ("CDI") on citizens, enemy aliens, and foreign nationals, who might be dangerous. The Second War Powers Act of 1941 repealed the legal protection of confidential census data, which was not restored until 1947. This information facilitated the internment of Japanese-Americans, following the Japanese attack on the U.S. at Pearl Harbor on December 7, 1941 and the internment of Italian- and German-Americans following the United States' entry into World War II.^[10][11]

In 1980, four FBI agents went to the Census Bureau's Colorado Springs office with warrants to seize Census documents, but were forced to leave with nothing. Courts upheld that no agency, including the FBI, has access to Census data.^[12]

Data analysis[link]

The census records and data specific to individual respondents are not available to the public until 72 years after a given census was taken, but aggregate statistical data derived from the census are released as soon as they are available. The 72-year rule is not law, but a rule posed by Roy V. Peel, Census Bureau Director, in a letter to Wayne C. Grover, Archivist, on August 26, 1952.^[13] Every census up to and including 1940 is currently available to the public and can be viewed on microfilm released by the National Archives and Records Administration, the official keeper of archived federal census records. Complete online census records can be accessed for no cost from National Archives facilities and many libraries,^[14] and a growing portion of the census is freely available from non-commercial online sources.^[15][16][17]

Census microdata for research purposes are available for censuses from 1850 forward through the Integrated Public Use Microdata Series (IPUMS), and scanned copies of each of the decennial census questionnaires are available online from many websites. Computerized aggregate data describing the characteristics of small geographic areas for the entire period from 1790 to 2000 are available from the National Historical Geographic Information System.

Regions and divisions[link]

US Census Bureau Population Regions

The bureau recognizes four census regions within the United States and further organizes them into nine divisions. These regions are groupings of states that subdivide the United States for the presentation of data. They should not be construed as necessarily being thus grouped owing to any geographical, historical, or cultural bonds.

Robert Groves
Director of the Census Bureau
Incumbent
Assumed office July 15, 2009
President	Barack Obama
Preceded by	Thomas Mesenbourg (Acting)
Personal details
Born	(1948-09-27) September 27, 1948 (age 63) Kansas City, Missouri, U.S.
Alma mater	Dartmouth College University of Michigan, Ann Arbor

Robert Martin Groves (born September 27, 1948)^[1] is the Director of the United States Census Bureau, a sociologist, and research professor in survey methodology at both the University of Michigan and University of Maryland, College Park. On April 10, 2012, he was named the Provost of Georgetown University. He was an associate director and later a visiting researcher at the Census Bureau from 1990 to 1992, and he has published several books on statistical sampling.

Early life[link]

Groves was born in Kansas City, Missouri, grew up in Metairie, Louisiana, and graduated in 1966 from De La Salle High School in New Orleans.^[1][2] In 1970, he graduated (summa cum laude, Phi Beta Kappa) from Dartmouth College with an A.B. degree^[3] in sociology.^[4] He later earned two M.A. degrees (sociology and statistics, both 1973) and a PhD (sociology, 1975) from the University of Michigan.^[4][5]

United States Census Bureau[link]

When Groves was an associate director at the United States Census Bureau in the early 1990s, he argued that potentially millions of minorities who typically voted Democratic were being undercounted. Groves advocated for the use of statistical adjustments to account for this discrepancy. George H. W. Bush's Commerce Secretary Robert Mosbacher blocked this suggestion. The Census Bureau is a component of the U.S. Department of Commerce.^[4]

On April 2, 2009, Groves was nominated by President Barack Obama to head the Census Bureau.^[6] During his confirmation hearings, Republican senators raised concerns based on Groves' previous actions that he would apply statistical adjustments to populations believed to be undercounted, thereby inflating their numbers and affecting the apportionment of congressional seats. Groves ruled out the use of statistical adjustments during the hearings and his nomination quickly proceeded to the full Senate in May. However, senators Richard Shelby and David Vitter continued to delay his confirmation due to lingering worries regarding statistical adjustments. They also sought assurance from the Obama administration that the controversial community group ACORN would not be involved in grassroots outreach related to the 2010 Census. On July 13, 2009, after several weeks of opposition by the two senators, Senate majority leader Harry Reid used a procedural motion to force a vote that confirmed Groves, 76-15.^[7] He took office July 15, 2009.^[8][9]
