To help policy makers, election officials, and others compare election administration policy and performance across states and from one election cycle to the next.
Launched in 2013 by the Pew Charitable Trusts, the Elections Performance Indexmeasures the effectiveness of state election administration based on seventeen indicators, including the percentage of absentee, provisional, and military and overseas ballots that were rejected; voter registration and turnout rates; voting wait time; and whether online registration is available, data are complete, and post-election audits are required.

Visitors to the site can explore state rankings for each indicator, as well as each state's overall EPI average, which is calculated from its performance on all seventeen indicators relative to every other state. For example, a 100 percent EPI number would indicate the state performed best among all states on every indicator in both 2008 and 2010, while a 0 percent number would mean the state performed worst among all states. An interactive chart of state-by-state data for each indicator allows the user to customize views by individual indicator or a select group of indicators, by election year, or as a bar graph or table. State profiles include a summary of notable indicators for each year. The site also includes links to related Pew research and analysis.
