How many people live in the US, and how old is our estimate?
A stored Census Bureau snapshot puts the July 1, 2024 resident population at about 340.1 million. That figure is a 2024-vintage estimate and, per the source note, not the latest release.
The short answer
The stored snapshot shows a US resident population of 340,110,988 people (about 340.1 million) for July 1, 2024 [D1]. It is a 2024-vintage Census Bureau estimate covering the 50 states and DC, and the source itself says it is not the latest population release [D1]. The snapshot was retrieved on 2026-10-18 [D1].
The number and what it covers
The most recent value in the stored series is 340,110,988 residents, dated July 1, 2024 [D1]. The unit is people, and the geography is the United States, defined here as the 50 states plus the District of Columbia. Puerto Rico is reported separately and is not in this total [D1].
This is a resident population estimate, not a head count taken on a single day. The series is annual, with each value tied to July 1 of its year [D1].
How old the estimate is
Two dates matter, and they should not be mixed up. The reference date of the newest figure is July 1, 2024. The stored snapshot was retrieved on 2026-10-18 [D1]. The first date says what moment the number describes. The second says when this explainer's copy of the data was captured.
The source note describes the data as the 2024 vintage and states it is not the latest population release [D1]. A vintage is a particular edition of the estimates, and agencies can revise earlier years when a new edition comes out. This snapshot does not contain the newer release or tell us what it shows. It is also not a real-time count of the population.
The recent series in the snapshot
The snapshot includes five annual values, all from the same 2024 vintage [D1]: 331,577,720 for 2020; 332,099,760 for 2021; 334,017,321 for 2022; 336,806,231 for 2023; and 340,110,988 for 2024. In rounded terms, that runs from about 331.6 million to about 340.1 million.
Each listed value is higher than the one before it. This explainer does not calculate growth rates or year-to-year changes, and the snapshot does not break the totals into births, deaths or migration. It therefore cannot say what drove the pattern.
What this source can and cannot establish
The data supports a narrow claim: according to this stored Census Bureau series, the national resident population was about 340.1 million on July 1, 2024. It does not show the population today, state or local figures, age or demographic breakdowns, or the population including Puerto Rico.
What this cannot tell us
- This is a dated snapshot rather than the latest agency release. It does not establish the population today.
- The snapshot contains only national annual totals for 2020 to 2024, with no state, county, age, or component-of-change detail, and no explanation of why the totals changed.
- Puerto Rico and other territories are not included in the national total.
