Who could vote —
and when?

This timeline shows how voting access has expanded, narrowed, and been contested across U.S. history. The main graph follows the estimated share of the population that could vote, while each card highlights a key law or decision that shaped that story.

Interactive timeline

Voting rights expanded — and were pushed back.

The chart focuses on voting access share so the pattern is easier to see: when access broadens, the line rises; when rights are restricted or protections are weakened, the line can flatten or fall. Estimated eligible-voter totals remain available for context in the detail panel.

How to read this section: Each card marks a major moment in voting-rights history. The percentage chips show the estimated share of the population with access to vote at that moment, and the change chip shows whether access expanded or narrowed from the previous milestone.
What the line reveals: Voting rights do not move in one direction. The timeline shows an ongoing pattern of expansion, backlash, partial recovery, and renewed pressure over time.
