Women voter turnout, and how to read the data
The short answer
The main national source on turnout by sex is a Census Bureau survey supplement, which measures reported voting rather than counted ballots. Read the denominator before comparing any two numbers, because rates based on citizens differ from rates based on all adults.

What the source actually measures
After each federal election, the Census Bureau fields a supplement to the Current Population Survey asking whether people were registered and whether they voted. The results are published as a set of detailed tables covering sex, age, race and ethnicity, educational attainment, income, employment status, disability status, tenure, registration method, voting method, and reported reasons for not voting.
The supplement is a household survey. It reflects what respondents report, and it is weighted to national and state population estimates. It is not a ballot count and it does not identify how anyone voted.
Read these five things before quoting a number
| What to check | Why it matters |
|---|---|
| Release and table number | Tables are renumbered between releases, and a citation without a table number cannot be verified. |
| Denominator | Total population, citizen population, and registered voters produce different rates from the same behavior. |
| Population covered | Most tables cover the civilian noninstitutionalized population, which excludes some residents. |
| Margin of error | Differences smaller than the published error are not findings, especially at the state level. |
| Election type | Presidential year turnout and midterm turnout are not comparable series. |
What the data cannot tell you
- It cannot tell you how any group voted, because it does not ask for a candidate choice.
- It cannot confirm an individual’s participation, because it is a sample.
- It cannot explain a change on its own. A shift can come from a rule change, a competitive race, a survey change, or sampling variation.
- It cannot support a claim that women vote as a single bloc, and neither can any other source.
How this page will change
We publish estimates only after a person reviews the latest release against the source tables and records the release name, table number, denominator, and margin of error. When a new release arrives, the current figures move to a dated historical page and the newest release becomes the headline, rather than overwriting the older analysis.

The Census voting topic page links every release in the series, including state-level tables and historical time series back to the 1960s. Our methodology page describes how we verify and label any figure we publish, and our sources directory lists the tiers we use.
What the official record shows
These are survey estimates, not counts
The Current Population Survey Voting and Registration Supplement asks a sample of households whether a person was registered and whether they voted. Election offices count ballots. The two are different measurements and they do not match exactly.
Denominators change the answer
A turnout rate can be expressed as a share of the total voting-age population, of the citizen voting-age population, or of registered voters. The same underlying behavior produces different percentages under each denominator, so a comparison is only valid when both figures use the same one.
Every estimate carries sampling error
Census releases publish standard errors and margins of error. A gap between two groups that is smaller than the margin of error is not a finding, and a state-level estimate from a national sample is far less precise than the national figure.
Our perspective
Aggregate turnout is a starting point, not a story
Turnout numbers describe an outcome, not a motive. We use them to ask what changed in the rules, the calendar, and the administration of an election, and we avoid claims that any group votes as a bloc.
This panel states what we believe. It is labeled, it is separate from the record above, and it never changes the voting instructions on this site.
The strongest argument against our view
A reasonable objection is that self-reported voting is known to overstate turnout, since some respondents report voting when they did not, which makes the survey a weak basis for public argument. That is a real limitation. It is also why the survey is best used for comparisons across groups and over time within the same series, rather than as a substitute for official counts.
What remains uncertain
This page publishes no headline percentage. We will add a figure only after a reviewed snapshot of the latest Census release, with the release name, table number, denominator, and margin of error stated on the page.
