The Census Bureau today released a menu-driven, interactive web page giving users access for any state a series of graphs or voting maps showing the percentages of adults who voted in every congressional and presidential election between 1996 and 2010.
In addition to graphs showing voting and registration trends over the period, users may choose a given election year and find separate graphs showing voting and registration by the following characteristics: age, sex, educational attainment, and race and Hispanic origin.
Some analysis of the 2010 election is provided as well, as are thematic maps of states showing percent voting during each election. The statistics come from the Current Population Survey. See http://www.census.gov/hhes/www/socdemo/voting/index.html
