Iowa 2010 Census Selected Statistics

Redistricting Plan:    Current Congressional and State Legislative Districts

Definitions

Federal law requires districts to be of equal population. To calculate the Ideal Population size for a district, divide the state's (resident) total population by the number of districts in a legislative body.

Federal law requires districts comply with the Voting Rights Act. An indicator if a district is protected by the Voting Rights Act is if it's minority voting-age population is above fifty percent of the total voting-age population. The Census Bureau allows persons to declare that they are one or more of five races. Black Voting-Age Population is the total number of persons of voting age who indicated that they are African-American in one or more combination of race. In the tables below, this is also expressed as a percentage of the total voting-age population. The Census Bureau asks a separate question if a person is Hispanic. Hispanic Voting-Age Population is the total number of persons who indicated that they are Hispanic. In the tables below, this is also expressed as a percentage of the total voting-age population. Note that because the Census Bureau asks these two questions on race and ethnicity separately, these two categories are not mutually exclusive, that is, a person can be Black and Hispanic.
