The U.S. Census Bureau has released initial results of Census 2010 showing a total resident U.S. population on April 1, 2010, was 308,745,538, a 9.7 percent over the 2000 U.S. resident population of 281,421,906. The state-by-state population figures will now be used for apportionment.

Census 2010 Apportionment

State population totals from this initial census data will be used in the process of apportionment to divide the 435 seats in the U.S. House of Representatives among the states. The apportionment population consists of the resident population of the 50 states, plus the overseas military and federal civilian employees and their dependents living with them who could be allocated to a state. The populations of the District of Columbia and Puerto Rico are excluded from the apportionment population, as they do not have voting seats in Congress.

As a result of the 2010 Census population totals, each member of the 435 members of the House of Representatives will represent, on average, about 710,767 people, compared to about 625,000 in 2000.

President Obama will transmit the apportionment counts to the 112th Congress during the first week of its first regular session in January 2011. The new apportionment results will be applied to the 113th Congress, which will convene in January 2013.

2010 State Population Trends

Census 2010 showed the most populous state to be California (37,253,956); the least populous, Wyoming (563,626). The state that gained the most numerically since the 2000 Census was Texas (up 4,293,741 to 25,145,561) and the state that gained the most as a percentage of its 2000 Census count was Nevada (up 35.1% to 2,700,551).

Regionally, the South and the West picked up the bulk of the population increase, 14,318,924 and 8,747,621, respectively. But the Northeast and the Midwest also grew: 1,722,862 and 2,534,225.

States Gaining and Losing Representation

As a result of the Census 2010 apportionment process, eight states will gain at least one new U.S. Representative beginning in the 113th Congress, while ten states will lose at least on seat in the House. (See: 2010 Apportionment Map or Table)

Let the Redistricting Begin
