How many registered voters in the US
Executive summary
The most reliable federal snapshot says 73.6% of the voting‑age population was registered for the 2024 presidential election, a registration rate produced by the Census Bureau’s Current Population Survey (CPS) supplement [1]. Exact headline counts vary across trackers and years—Census/Statista reports about 161.4 million registered in 2022 while other aggregators cite roughly 168 million in 2020—so the best short answer is: roughly 160–170 million registered voters in the United States, with the CPS percentage providing the most recent official coverage of registration rates [2] [3] [1].
1. The federal baseline: CPS registers the rate, not a single static headcount
The Census Bureau’s CPS Voting and Registration Supplement is the standard federal instrument for comparing registration and turnout across elections, and it reported that 73.6% of the voting‑age population was registered in the 2024 presidential cycle, with 65.3% actually voting [1]. The CPS produces percentages and demographic breakdowns rather than a single immutable national roster, which is why analysts pair the CPS rates with state registration rolls to produce headline counts [4] [5].
2. Historic and alternate headline totals: a 160–170 million band
Public trackers and archival tables provide concrete past totals: Statista (citing Census compilation) lists 161.42 million registered voters in 2022 [2], while some aggregated summaries that compare 2020 figures place registered voters near 168 million [3]. WorldPopulationReview and other aggregators rely on state offices and projection models, producing estimates that sit within this same broad band—hence the practical working range of roughly 160–170 million registered voters nationwide [6] [3] [2].
3. Party and demographic contours inside that total
Party registration totals are available only from states that collect party affiliation on their rolls; aggregations show about 44.1 million registered Democrats and 37.4 million registered Republicans in mid‑2025, but those figures represent the subset of registrants who declare a party and exclude independents and no‑party states [7]. The gender gap in registration is also material: women outnumber men by roughly 8.7 million registered voters as of 2024, according to election‑data compilations [8].
4. Why exact counts move and why the range matters
No single, permanently authoritative national list exists because registration is state‑administered, continuously updated, and subject to purges, additions, and differing rules about affiliation and inactive status; independent projects (like IVP) and media compilations blend state rolls, party files and modelled projections—so counts can diverge depending on methodology and timing [6] [9]. Analysts therefore treat the CPS registration rate as the canonical comparative measure while using state and third‑party totals to produce headline numbers, producing the observed 160–170 million range [1] [2] [3].
5. What’s missing or disputed in the coverage
Public sources in this packet do not offer a single, definitive January 2026 national headcount based on synchronized state rolls; instead they provide the CPS percentage for 2024 plus scattered state and aggregator totals from 2020–2022 and party‑declared snapshots in 2025 [1] [2] [7] [3]. That limitation means any precise figure cited as “the number of registered voters today” must be accompanied by the source, date and methodology; absent a consolidated, roll‑by‑roll, contemporaneous federal count, the cautious conclusion is the range above, anchored by the CPS registration rate [1] [2].
