About these figures

Counts are what state election offices report to the US Election Assistance Commission (EAVS) after each November election; questions and state practice change between years. The share is active voters over the Census Bureau's citizen voting-age population estimate (CVAP). The survey line is self-reported (Current Population Survey) and kept separate from the office counts.

Missouri registers voters by party; its figures are not yet collected here.
