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.

Environmental Health & Justice

Clean air and water, safe housing, and climate resilience are health policy—because place shapes lifespan.

Disproportionate Burdens

Historically redlined neighborhoods are more likely to face heat islands, highway pollution, industrial hazards, and aging housing with lead and mold—driving asthma, cardiovascular disease, and missed school/work.

Policy Priorities

  • Targeted Investments: Direct public funds to high-burden census tracts.
  • Stronger Standards: Enforce air, water, and housing codes; accelerate lead abatement.
  • Climate Resilience: Cooling centers, tree canopy, flood protections, and backup power for clinics.
  • Health in All Policies: Include health impact assessments in transportation and land-use decisions.
