Census regions and divisions The United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are widely used for data collection and analysis. The Census Bureau definition is pervasive. The
territories are not included, but the
District of Columbia is. Regional divisions used by the United States Census Bureau:
History The first census was collected in 1790 and published in 1791.
Uses of census data 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 US, • Plan transportation systems and roadways, • Determine quotas and creation of police and fire precincts, and • Create localized areas for elections, schools, utilities, etc. • Gathers population information every 10 years Census data is used to determine how seats of Congress are distributed to states. The census data is also used by the Bureau to obtain a real-time estimate in U.S. and World Population Clock. Only people who live in the 50 states and within the District of Columbia are included in the estimation.
Data stewardship 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 an
affidavit of non-disclosure prior to employment. This non-disclosure states "I will not disclose any information contained in the schedules, lists, or statements obtained for or prepared by the Census Bureau to any person or persons either during or after employment." The punishment for breaking the non-disclosure is a fine up to $250,000 or five years in prison. The bureau cannot share responses, addresses or personal information with anyone, including the United States or foreign governments, or law enforcement agencies such as the
IRS,
FBI, or
Interpol. "[P]roviding quality data for public good while respecting individual privacy and protecting confidentiality – is the Census Bureau's core responsibility"; "Keeping the public's trust is critical to our ability to carry out our mission as the leading source of quality data about the nation's people and economy." Only after 72 years does the information collected become available to other agencies or the general public. Seventy-two years was picked because usually by 72 years since the census is taken, most participants would be deceased. 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. United States census data are valuable for the country's political parties;
Democrats and
Republicans are highly interested in knowing the accurate number of persons in their respective districts. These insights are often linked to financial and economic strategies that are central to federal, state and city investments for locations of particular populations. Such apportionments are designed to distribute political power across neutral spatial allocations; however, "because so much is at stake, the census also runs the risk of being politicized." Such political tensions highlight the complexity of
identity and
classification; some argue that unclear results from the population data "is due to distortions brought about by political pressures." One frequently used example includes ambiguous ethnic counts, which often involves underenumeration and/or undercounting of minority populations. The United States Census Bureau began pursuing technological innovations to improve the precision of its census data collection in the 1980s. Robert W. Marx, the Chief of the Geography Division of the USCB, teamed up with the
U.S. Geological Survey and oversaw the creation of the
Topologically Integrated Geographic Encoding and Referencing (TIGER) database system. Census officials were able to evaluate the more sophisticated and detailed results that the TIGER system produced; furthermore, TIGER data is also available to the public. And while the TIGER system does not directly amass demographic data, as a
geographic information system (GIS), it can be used to merge
demographics to conduct more accurate geospatial and mapping analysis. In July 2019, the Census Bureau stopped releasing new data via American FactFinder, which was decommissioned in March 2020 after 20 years of being the agency's primary tool for data dissemination. The new platform is data.census.gov.
Ongoing surveys Throughout the decade between censuses, the bureau 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 over 130 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: Other surveys conducted The Census Bureau also collects information on behalf of survey sponsors. These sponsors include the
Bureau of Justice Statistics (BJS), the
Department of Housing and Urban Development (HUD), the
National Center for Education Statistics (NCES), and the
National Science Foundation (NSF), among others. == Organizational structure ==
