2000 census of the United States

The Twenty-Second , known as Census 2000 and conducted by the, determined the resident population of the on , , to be 281,421,906, an increase of 13.2% over the 248,709,873 persons  during the. This was the twenty-second federal census and the largest single civil administrative peacetime effort in the history of the United States.

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

Population profile

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


 * 75.1% of respondents said they were and no other race;
 * 21.36% (60 Million Americans) are of descent;
 * 12.3% are of Black or descent;
 * — who may belong to any race — accounted for 12.5% of the U.S. population, up from 9% in 1990;
 * 3.6% of respondents are Asian;
 * 2.4% of respondents are (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 outnumber men two to one amongst those aged 85 and older;
 * Almost one in five adults had some type of in 1997 and the likelihood of having a disability increased with age;
 * Families (as opposed to men or women living alone) still dominate American households, but less so than they did thirty years ago;
 * Since 1993, both families and nonfamilies have seen median household incomes rise, with "households headed by a woman without a spouse present" growing the fastest;
 * People in married-couple families have the lowest rates;
 * The poor of any age are more likely than others to lack coverage, although no coverage is needed for essential to life services or operations at any age;
 * The number of and  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 (52%) of U.S. households have access to ; 41% have.

Reapportionment


The results of the census are used to determine how many s each state is. Congress defines the formula, in accordance with Title 2 of the U.S. Code, to reapportion among the states the 435 seats in the. 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, the first census, the decennial count has been the basis for the 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 was fixed at 435. Today, each member represents about 19 times as many constituents.

Adjustment controversy
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. (See here and here for background.)

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. This recommendation was followed by the Secretary of Commerce (the official in charge of making the determination).

Utah controversy
The strongest disputation of the apportionment results came from the state of, which challenged the results in two different ways. Utah was extremely close to gaining a fourth congressional seat. The Census Bureau counted members of the military serving abroad as residents of their home state, but did not count people from Utah traveling abroad as religious missionaries as residents. If this policy were changed, then Utah would have received an additional seat at the expense of. After losing a lawsuit over this matter, 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. This case made it to the Supreme Court, but Utah was again defeated.

Gay and lesbian controversy
The census forms did not include a single question regarding sexual preference, 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. Responses were tabulated and the 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. For every same-sex couple tallied in the census, there could be three to six more homosexual un-partnered individuals who wouldn't be counted as gay. The Census reported that same-sex male couples numbered 336,001 and female same-sex couples numbered 329,522. 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 can't be known because the Census didn't count them specifically. Bisexual and transgendered populations weren't counted, either, as there were no questions regarding this information. Missing, too, are data from additional couples living under the same roof as the first, though this lack applies as well to additional heterosexual couples under the same roof. 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. It also makes for less accuracy when predicting the fertility of a population.

Another issue that concerned gay rights advocates involved the automatic changing of data during the tabulation process. This automatic software data compiling method, called, 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 by the Census computers as a discrepancy. The Census Bureau explained that 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. The process of automatic reassignment of same-sex marriage data was initiated so that the Census Bureau would not contravene the passed in 1996. The Act states:
 * In determining the meaning of any Act of Congress, or of any ruling, regulation or interpretation of the various administrative bureaus and agencies of the United States, the word 'marriage' means only a legal union between one man and one woman as husband and wife, and the word 'spouse' refers only to a person of the opposite sex who is a husband or wife.

The word 'spouse' did not appear on the 2000 Census questionnaires.

With allocation moving married same-sex couples to the unmarried partner category, statisticians lost any data that could have been extracted relating to the social stability of a same gender couple who identify themselves as married.
