The Twenty-second United States Census, known as Census 2000 and conducted by the Census Bureau, determined the resident population of the United States on April 1, 2000, to be 281,421,906, an increase of 13.2% over the 248,709,873 persons enumerated during the 1990 Census.^[1] This was the twenty-second federal's census and was at the time the largest civility administrative peacetime effort in the United States.^[2]

Approximately 16 percent of households received a "long form" of the 2000 census, which contained over 100 questions. Full documentation on the 2000 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series.

Data availability[link]

Microdata from the 2010 census is freely available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System.

Population profile[link]

The U.S. resident population includes the total number of people in the 50 states and the District of Columbia. The Bureau also enumerated the residents of the associated state of Puerto Rico; its population was 3,808,610, an 8.1% increase over the number from a decade earlier.

In an introduction to a more detailed population profile (see references below), the Census Bureau highlighted the following facts about U.S population dynamics:

• 75% of respondents said they were White or Caucasian and no other race;
• Hispanics accounted for 12.5% of the U.S. population, up from 9% in 1990;
• 12.3% (34.5 million Americans) were of German descent; German Americans
• 12.3% were of Black or African American descent;
• 3.6% of respondents were Asian;
• 2.4% (6.8 million Americans)^[3] of respondents were multiracial (2 or more races). The 2000 Census was the first time survey options for multiracial Americans were provided.
• Between 1990 and 2000, the population aged 45 to 54 grew by 49% and those aged 85 and older grew 38%;
• Women outnumbered men two to one among those aged 85 and older;
• Almost one in five adults had some type of disability in 1997 and the likelihood of having a disability increased with age;
• Families (as opposed to men or women living alone) still dominated American households, but less so than they did thirty years ago;
• Since 1993, both families and non-families have seen median household incomes rise, with "households headed by a woman without a spouse present" growing the fastest;
• People in married-couple families had the lowest poverty rates;
• The poor of any age were more likely than others to lack health insurance coverage;
• The number of elementary and high school students in 2000 fell just short of the all-time high of 49 million reached in 1970;
• Improvements in educational attainment cross racial and ethnic lines; and
• The majority (51%) of U.S. households had access to computers; 42% have Internet access.^[4]

Changes in population[link]

Regionally, the South and West experienced the bulk of the nation's population increase, 14,790,890 and 10,411,850, respectively. This meant that the mean center of U.S. population moved to Phelps County, Missouri. The Northeast grew by 2,785,149; the Midwest by 4,724,144.

Reapportionment[link]

The results of the census are used to determine how many congressional districts each state is apportioned. Congress defines the formula, in accordance with Title 2 of the U.S. Code, to reapportion among the states the 435 seats in the United States House of Representatives. The apportionment population consists of the resident population of the fifty states, plus the overseas military and federal civilian employees and their dependents living with them who could be allocated to a state. Each member of the House represents a population of about 647,000. The populations of the District of Columbia and Puerto Rico are excluded from the apportionment population because they do not have voting seats in the U. S. House of Representatives.

Since the first census in 1790, the decennial count has been the basis for the United States representative form of government. Article I, Section II specifies that "The Number of Representatives shall not exceed one for every thirty Thousand, but each State shall have at Least one Representative." In 1790, each member of the House represented about 34,000 residents. Since then, the House more than quadrupled in size, and in 1911 the number of representatives was fixed at 435. Today, each member represents about 20 times as many constituents.

Adjustment controversy[link]

In the years leading up to the 2000 census, there was substantial controversy over whether the Bureau should adjust census figures based on a follow-up survey, called the post-enumeration survey, of a sample of blocks. (In 1999, the Supreme Court ruled 5-4 that the Constitution prohibits the use of such figures for apportionment purposes, but it may be permissible for other purposes where feasible.) The controversy was partly technical, but also partly political, since based on data from the 1990 census both parties believed that adjustment would likely have the effect, after redistricting, of slightly increasing Democratic representation in legislative bodies, but would also give Utah an additional, probably Republican, representative to Congress.^[5][6]

Following the census, discrepancies between the adjusted census figures and demographic estimates of population change could not be resolved in time to meet legal deadlines for the provision of redistricting data, and the Census Bureau therefore recommended that the unadjusted results be used for this purpose.^[7] This recommendation was followed by the Secretary of Commerce (the official in charge of making the determination).

Utah controversy[link]

After the census was tabulated, Utah challenged the results in two different ways. Utah was extremely close to gaining a fourth congressional seat, falling 857 people short, which in turn was allocated to North Carolina. The margin was later shortened to 80 people, after the federal government discovered that it overcounted the population of North Carolina by 2,673 residents.^[8] The Census Bureau counted members of the military and other federal civilian employees serving abroad as residents of their home state but did not count other individuals living outside the United States. Utah claimed that individuals traveling abroad as religious missionaries should be counted as residents and that the failure to do so imposed a burden on Mormon religious practice. Almost half of all Mormon missionaries, more than 11,000 individuals, were from Utah; only 102 came from North Carolina. If this policy were changed, then Utah would have received an additional seat instead of North Carolina. On November 26, 2002, the Supreme Court affirmed the lower court ruling that rejected Utah's efforts to have Mormon missionaries counted.^[9]

The state of Utah then filed another lawsuit alleging that the statistical methods used in computing the state populations were improper and cost Utah the seat. The Bureau uses a method called imputation to assign a number of residents to addresses where residents cannot be reached after multiple efforts. While nationwide the imputation method added .4% to the population, the rate in Utah was .2%. The state challenged that the use of imputation violates the Census Act of 1957 and that it also fails the Constitution's requirement in Article I, Section 2 that an "actual enumeration" be used for apportionment.^[10] This case, Utah v. Evans, made it to the Supreme Court, but Utah was again defeated.^[11]

Gay and lesbian controversy[link]

The census forms did not include any questions regarding sexual orientation, making it impossible to compile data comparing heterosexual and homosexual populations. However, two questions were asked that allowed same-sex partnerships to be counted. The questionnaires asked the sex of each person in a household and they asked what the relationship was between each of the members of the household. Respondents could check "Husband/wife" or "unmarried partner" or a number of other relationships.^[12][13] Responses were tabulated and the Census Bureau reported that there were more than 658,000 same-sex couples heading households in the United States. However, only about 25% of gay men and 40% of lesbians are in shared-household partnerships at any one time, according to non-Census surveys.^[14] For every same-sex couple tallied in the census, there could be three to six more homosexual un-partnered individuals who would not be counted as gay. The Census reported that same-sex male couples numbered 336,001 and female same-sex couples numbered 329,522.^[15] Extrapolating from those figures and the surveyed partnering habits of homosexuals, as many as 4.3 million homosexual adults could have been living in the U.S. in 2000. The exact number cannot be known because the Census did not count them specifically. Bisexual and transgender populations were not counted, either, because there were no questions regarding this information. Also unavailable is the number of additional same-sex couples living under the same roof as the first, though this applies to additional heterosexual couples as well. The lack of accurate numbers makes it difficult for lawmakers who are considering legislation on hate crimes or social services for gay families with children.^[16] It also makes for less accuracy when predicting the fertility of a population.^[17]

Another issue that concerned gay rights advocates involved the automatic changing of data during the tabulation process. This automatic software data compiling method, called allocation, was designed to counteract mistakes and discrepancies in returned questionnaires. Forms that were filled out by two same-sex persons who checked the "Husband/wife" relationship box were treated as a discrepancy. The Census Bureau explained that same-sex "Husband/wife" data samples were changed to "unmarried partner" by computer processing methods in 99% of the cases. In the remaining 1%, computer systems used one of two possibilities: a) one of the two listed sexes was changed, making the partnership appear heterosexual, or b) if the two partners were more than 15 years apart in age, they might have been reassigned into a familial parent/child relationship.^[18] The process of automatic reassignment of same-sex marriage data was initiated so that the Census Bureau would not contravene the Defense of Marriage Act passed in 1996. The Act states:

With allocation moving married same-sex couples to the unmarried partner category, social scientists lost information that could have been extracted relating to the social stability of a same gender couple who identify themselves as married.^[17]

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
