U.S. Voter Turnout & Voting Law History

How many Americans actually vote, and how have the rules changed? This page holds national turnout records from 1789 to 2024, a searchable timeline of major voting laws from the 15th Amendment to today, third-party performance history, and a turnout simulator you can adjust by age group. Filter any dataset, switch between chart and table views, and export what you find to CSV.
