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.
Party figures are the state office's own latest report, read directly from its published file.
The AVR mark is the year automatic voter registration began in Pennsylvania, from the Brennan Center's list.
