Short Answer
The United States population reached 341,784,857 on July 1, 2025, according to the U.S. Census Bureau’s Vintage 2025 national population estimates. That figure represents an increase of about 1.8 million people, or 0.5%, from the previous year — the slowest annual growth since the early COVID-19 pandemic period. By July 22, 2026, the Census Bureau’s population clock had risen to 342,684,908, reflecting continued but modest growth. This article breaks down the latest official numbers, the forces behind the slowdown, and why the count matters.

Explanation
The U.S. population is the total number of people residing in the 50 states and the District of Columbia, as estimated by the Census Bureau. The estimate is not a head count but a demographic calculation that starts with the 2020 Census and adds births, subtracts deaths, and accounts for net international migration each year.
In 2025, the population grew by only 0.5%, a sharp slowdown from 1.0% in 2024. The main reason was a historic drop in net international migration, which fell from 2.7 million in the 2023–2024 period to 1.3 million in 2024–2025. Births and deaths remained relatively stable, so migration was the dominant swing factor.
Even with the slowdown, the United States remains the third-most-populous country in the world, after India and China. The population clock, which projects current numbers based on recent trends, shows the country adding one person every 28 seconds on average.
Definition
In official Census Bureau statistics, the resident population of the United States includes all people living in the 50 states and the District of Columbia. It excludes residents of U.S. territories such as Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana Islands, which are reported separately. The estimate covers both civilian and military personnel stationed in the United States, as well as institutionalized populations.
The term population estimate refers to a figure calculated for a date after the most recent decennial census. The Census Bureau produces annual estimates each year, known by their “vintage” — for example, Vintage 2025 covers July 1, 2025.
Historical Data
The table below shows key official U.S. population figures from the 2020 Census through the most recent estimates and the population clock reading in July 2026.
| Date | Population | Source/Type |
|---|---|---|
| April 1, 2020 | 331,449,281 | 2020 Census count |
| July 1, 2024 | 340,110,988 | Vintage 2024 estimate |
| July 1, 2025 | 341,784,857 | Vintage 2025 estimate |
| July 1, 2026 | 342,620,143 | Population clock/estimate |
| July 22, 2026 | 342,684,908 | Population clock reading |
Between April 1, 2020, and July 1, 2025, the U.S. population increased by 3.1%, or about 10.3 million people.
Year-over-Year Change
The annual growth rate has swung sharply in recent years. In 2024, the country added 3.2 million people, a growth rate of 1.0% — the fastest since 2006. In 2025, growth fell to 1.8 million people, or 0.5%, the slowest since 2021, when the population grew by just 0.2% during the pandemic.
| Period | Population increase | Growth rate |
|---|---|---|
| 2023–2024 | 3.2 million | 1.0% |
| 2024–2025 | 1.8 million | 0.5% |
| 2020–2021 (pandemic low) | — | 0.2% |
The 2024–2025 slowdown was driven almost entirely by the decline in net international migration, which fell by 1.4 million from the prior year.
National Comparison
The United States is the third-most-populous country in the world. According to the Census Bureau’s international population clock for July 1, 2026, India and China each have more than 1.4 billion people, while the United States is far behind at about 342.6 million but well ahead of Indonesia, the fourth-ranked country.
| Rank | Country | Population (July 1, 2026) |
|---|---|---|
| 1 | India | 1,429,700,205 |
| 2 | China | 1,405,918,803 |
| 3 | United States | 342,620,143 |
| 4 | Indonesia | 285,562,809 |
| 5 | Pakistan | 261,714,024 |
| 6 | Nigeria | 250,228,859 |
| 7 | Brazil | 222,624,000 |
| 8 | Bangladesh | 175,927,589 |
| 9 | Russia | 139,450,252 |
| 10 | Mexico | 132,807,523 |
Although the U.S. growth rate has slowed, it remains higher than many other high-income countries, largely because of international migration and a relatively younger population.
Factors Behind the Trend
The sharp slowdown in U.S. population growth in 2025 was not caused by a rise in deaths or a fall in births. According to Christine Hartley, assistant division chief for Estimates and Projections at the Census Bureau, births and deaths remained relatively stable. Instead, the change came from net international migration, which dropped from 2.7 million in the July 2023–June 2024 period to 1.3 million in July 2024–June 2025.
“The slowdown in U.S. population growth is largely due to a historic decline in net international migration, which dropped from 2.7 million to 1.3 million in the period from July 2024 through June 2025,” said Christine Hartley.
Net international migration is the number of people moving into the United States minus those leaving. It includes lawful permanent residents, temporary migrants, and unauthorized migrants, and it is the most volatile component of population change. The 2024 spike reflected a rebound from pandemic-era restrictions, while the 2025 decline brought migration closer to pre-pandemic norms.
How the Statistic Is Calculated
The Census Bureau does not count every person each year. Instead, it produces population estimates using a demographic balancing equation. The process starts with the most recent decennial census count — in this case, the April 1, 2020 Census — and then adds or subtracts components of change for each subsequent year.
- Births are added to the population.
- Deaths are subtracted.
- Net international migration is added (or subtracted if negative).
- Net domestic migration is not relevant at the national level but is used for state and county estimates.
The population clock uses the same components but applies current rates — such as one birth every 8 seconds and one death every 11 seconds — to project the population forward in real time. The clock is an approximation, not an official count.
Limitations of the Data
Population estimates are subject to revision as new data become available. The Census Bureau releases a new “vintage” each year, and earlier years may be revised. For example, the Vintage 2025 estimates may update the 2024 figure that was originally published in Vintage 2024.
Net international migration is especially difficult to measure because it relies on administrative records, survey data, and assumptions about unauthorized migration. The 2024–2025 decline of 1.4 million is a large swing, and future revisions could change the exact magnitude. The population clock is even less precise because it assumes current birth, death, and migration rates will continue unchanged.
Finally, the national total excludes U.S. territories, so it does not represent all people under U.S. sovereignty. Puerto Rico alone has about 3.2 million residents, but it is reported separately.
Why It Matters
The U.S. population count is more than a number. It determines how many seats each state gets in the U.S. House of Representatives, how hundreds of billions of dollars in federal funding are distributed, and how businesses and governments plan for schools, housing, transportation, and health care.
Slower population growth can ease pressure on infrastructure and housing in the short term, but it also raises long-term concerns about labor force growth, supporting an aging population, and maintaining economic dynamism. The 2025 slowdown highlights how sensitive U.S. population trends are to immigration policy and global migration patterns.

Where does the United States rank in world population?
The United States is the third-most-populous country, behind India and China. As of July 1, 2026, the U.S. population was about 342.6 million, compared with more than 1.4 billion in India and China.
Does the U.S. population total include Puerto Rico and other territories?
No. The national resident population total covers the 50 states and the District of Columbia. U.S. territories such as Puerto Rico are reported separately.
