The United States Elections Project is an information source for the United States electoral system. The mission of the project is to provide timely and accurate election statistics, electoral laws, research reports, and other useful information regarding the United States electoral system. By providing this information, the project seeks to inform the people of the United States on how their electoral system works, how it may be improved, and how they can participate in it.
IMPORTANT UPDATE: Voter turnout data and analyses can now be found on the new UF Election Lab website. The Lab's website has a data archive that will provide better data versioning for when I update statistics. You can find the latest 2022 turnout rate data with visualizations here. You can also find these visualization of historical turnout rates and turnout rates by demographic groups.
