Demographics of the United States

Encyclopedia : D : DE : DEM : Demographics of the United States


The demographics of the United States depict a largely urban nation, with 75% of its population living in urban and suburban areas. The mean population center of the United States has consistently shifted westward and southward, with California and Texas currently the most populous states.

As of 2006, the population of the United States is 299,215,591. The U.S. population is characterized as slow growth, with a large baby boomer cohort. Births, supplemented by immigration, help to offset the aging population. The total U.S. population crossed the 200,000,000 mark in 1968, and the 100,000,000 mark around 1915. The U.S. population more than tripled during the 20th century, a growth rate of about 1.3% a year, having been about 76 million in 1900.

Ethnic groups

Main article: Racial demographics of the United States
According to the Census Bureau, as of 2004, America's racial composition is: The Census Bureau considers Hispanic to be any person with national origins in Latin America or Spain (ie. Spaniards, Cubans, Mexicans, Puerto Ricans, Dominicans, etc.), and thus may be of any race.

The Census Bureau's definition of "white" is not necessarily the definition most widely held by Americans in general. Most Americans define "white" to exclude all Hispanics, even those of exclusive or predominanty European descent. Using that definition, the white proportion of the U.S. population is currently at 67.4%.
Of course, by the same definition, the numbers for each of the other races would be reduced if one were to take into account the important amounts of each group who define themselve as mixed ancestry rather than solely African American, Asian American or Native American.

The American Religious Identification Survey (ARIS) 2001 was based on a random digit-dialed telephone survey of 50,281 American residential households in the continental U.S.A (48 states). Respondents were asked to describe themselves in terms of religion with an open-ended question. Interviewers did not prompt or offer a suggested list of potential answers. The primary question of the interview was: What is your religion, if any? The religion of the spouse/partner was also asked. If the initial answer was 'Protestant' or 'Christian' further questions were asked to probe which particular denomination.
