The estimated number of voting-age Americans who reported being registered but did not report voting in each federal election.
What this chart says
In the 2024 CPS, the gap between reported registration and reported voting was about 19.5 million people.
How to read it
Calculated as voting-age population multiplied by the difference between the Census reported-registration and reported-voting rates.
Important limits
- This is a difference between two survey estimates, not a count of named registered nonvoters.
- Self-reporting error and survey sampling error apply to both component estimates.
