On December 21, 2010, the U.S. Census Bureau announced that the resident population of the United States, which includes the 50 states and the District of Columbia, was 308,745,538. The U.S. population had grown by 9.7 percent since 2000. Population growth in the Sun Belt continued to outpace that of other regions. The South and the West showed the greatest increase: 14,318,924 and 8,747,621, respectively. The Northeast and the Midwest also grew, but at a much slower rate. The chief reason for the census, which is constitutionally mandated, is to determine official population counts for assigning seats in the House of Representatives.
Gains and losses in population over each 10-year period effect changes in the number of states’ representatives in Congress. California remains the most populous state, with 37,253,956, and will retain the highest number of representatives: 53. Texas is the state whose population increased the most since the 2000 census; it therefore will gain the most representatives: four. Florida will gain two representatives, and other fast-growing states including Arizona, Georgia, Nevada, South Carolina, Utah, and Washington will gain one each. States that experienced slower rates of growth will lose representatives. The congressional delegations of New York and Ohio will each shrink by two, while Illinois, Iowa, Louisiana, Massachusetts, Michigan, Missouri, New Jersey, and Pennsylvania will lose one representative apiece. Of these, only Michigan saw an actual decline in population since 2000.
The number of each state’s representatives also determines its electoral vote, which is key to presidential elections. Each state’s electoral vote equals the number of its representatives plus senators. The current changes will become effective in the 2012 national election.
