How These Charts Were Built

Data Sources:

  • Voter registration totals from official state election offices
  • Voting-age population estimates from the U.S. Census Bureau’s CVAP tabulation

Methodology: Registration rates were calculated by dividing total registered voters by the estimated voting-age population for each county. Where racial breakdowns were available, Black registration rates were compared directly to Black voting-age population. Averages were derived across selected counties to illustrate structural exclusion and civic potential.
