Fact check: How many eligible voters did not cast ballots in the 2024 election?

Checked on October 15, 2025

Executive Summary

The available materials do not provide a single definitive count of eligible voters who did not cast ballots in the 2024 general election, but they allow a reasoned range: roughly 20 million registered voters did not vote, and a larger pool of eligible but unregistered citizens likely raises non-voter totals substantially. Published analyses and official tables emphasize distinctions between ballots cast, registered voters, and voting-eligible population; reconciling these yields the best-supported estimate from the provided documents [1] [2] [3].

1. What the reporting claims and where they conflict — parsing the major assertions

Several supplied items make distinct claims: the U.S. Census Bureau tables state turnout percentages and raw vote totals, news analyses report record turnout and compare 2024 to prior cycles, while state-focused pieces highlight local variations. One analysis converts turnout percentages into a 20 million shortfall among registered voters by contrasting 174 million registered with 154 million who voted [1]. Other items emphasize high overall turnout or primary non-participation rates without producing a nationwide non-voter count, creating apparent contradictions that reflect differing denominators rather than factual disagreement [4] [2].

2. The strongest single data point: Census registration and vote counts

The most concrete figures in the materials come from the U.S. Census Bureau summary tables showing 154 million ballots cast (65.3% of the voting-age population) and 174 million registered voters (73.6%), yielding about 20 million registered-but-nonvoters when subtracting ballots from registered registrants [1]. This administrative and survey-derived data is the best anchor for a national registered-voter non-voting figure because it pairs both registration and votes cast on the same population base and is dated April 2025 in the provided analyses [1].

3. Eligible but unregistered people expand the non-voter pool — how much is missing?

Analysts point out that many eligible citizens remain unregistered, and counting only registered non-voters undercounts the larger set of eligible non-voters. One piece cites prior research showing tens of millions sat out the 2020 election, and the 2024 context likely includes millions of eligible but unregistered people; a Texas-focused analysis estimated 2.1 million eligible-but-unregistered Texans alongside 14.65 million registered non-voters in a primary context [3] [5]. Extrapolating nationally indicates that adding eligible-but-unregistered persons could raise the non-voter total well beyond the 20 million registered non-voters figure [5].

4. State-level variation matters — Michigan, Texas and the primaries tell different stories

State-specific reporting highlights wide variation in turnout: Michigan reportedly set a 72% turnout record while Texas primary non-participation data shows large numbers of registered voters abstaining [4] [5]. The Texas primary analysis tallied 16.73 million non-participants in that state when combining registered non-voters and eligible-but-unregistered people — a useful microcosm showing that local registration shortfalls and primary-vs-general differences can substantially change non-voter totals and that national aggregates mask important geographic divergence [5] [4].

5. Primaries versus general election: apples and oranges on participation

Several supplied analyses emphasize that primary turnout is much lower than general election turnout, with one organization reporting aggregate primary turnout near 23% and noting almost four-in-five registered voters did not cast a primary ballot [6]. This is a different phenomenon from general-election non-participation and must not be conflated; primary non-voting inflates public impressions of political disengagement but does not change the general-election non-voter count unless explicitly aggregated and weighted across states and demographics [6] [2].

6. Methodological caveats: definitions, timing, and data completeness

Reconciling these sources requires attention to definitions (registered voters vs. voting-eligible population), timing of publication, and whether counts are preliminary or final. Census tables cited here are finalized summaries through April 2025 and offer the most consistent denominators [1]. Other items are state analyses or primary-focused reports with different scopes and later or earlier publication dates [5] [6]. Mixing figures without aligning denominators produces misleading conclusions, which explains divergent headline claims across sources [1] [4].

7. Bottom line estimate and what remains uncertain

Based on the provided materials, the best-supported, conservative nationwide estimate is that about 20 million registered voters did not cast ballots in the 2024 general election, derived from the Census registration and vote totals [1]. Expanding to include eligible but unregistered citizens increases the non-voter pool substantially; available state-level illustrations and prior studies suggest the true number of eligible non-voters could be several tens of millions higher, but the precise national count remains uncertain in the supplied analyses [5] [3].
