The reason our Federal government conducts a census every 10 years is to determine the division of our representatives in Congress among the states. This fact often gets lost in all the hype about the Census. After the Census is completed, Congress reallocates the available seats in the U.S. House of Representatives (435). This happens in time for the General Elections two years after the Census year.
A study by Election Data Services indicates that South Carolina will gain one seat in the U.S. House of Representatives in beginning in 2012. EDS estimates that six states will gain one seat in Congress and one state, Florida, will gain two. Arizona, Georgia, Nevada, Utah, and Washington are the states in addition to South Carolina expected to pick up one seat in Congress.
When states gain a seat in Congress, that means other states lose seats. Eight states are expected to lose one seat each in Congress: Illinois, Iowa, Louisiana, Massachusetts, Michigan, Missouri, New Jersey, and Pennsylvania.
Once Congress reallocates seats in Congress, if South Carolina gains a seat, the South Carolina General Assembly will reapportion the state and draw new lines for its Congressional Districts.
