Population growth in U.S. metro areas as a whole was faster between 2023 and 2024 than in the previous year and outpaced that of the nation. Additionally, some metro areas that experienced population declines during the COVID-19 pandemic are now observing population gains, according to Vintage 2024 estimates of population totals and components of change released today by the U.S. Census Bureau.
“Increasingly, population growth in metro areas is being shaped by international migration,” said Kristie Wilder, a demographer in the Census Bureau’s Population Division. “While births continue to contribute to overall growth, rising net international migration is offsetting the ongoing net domestic outmigration we see in many of these areas.”
All of the nation’s 387 metro areas had positive net international migration between 2023 and 2024, and it accounted for nearly 2.7 million of the total population gain in metro areas — up from 2.2 million between 2022 and 2023. These trends were measured using an improved method that combines survey data and administrative data from other federal agencies.
The Population Estimates Program uses current data on births, deaths and migration to calculate population change since the most recent decennial census (2020 Census) and produce an annual time series of estimates of population. Today’s release includes population totals and components of change for U.S. counties and metropolitan and micropolitan statistical areas, and total population for Puerto Rico municipios and metropolitan and micropolitan statistical areas. Tables are available on <census.gov/popest>.
Key Takeaways
- Between 2023 and 2024, the number of people living in a U.S. metro area increased by nearly 3.2 million (or around 1.1%) to 293.9 million. In comparison, the total U.S. population increased by nearly 1.0% to more than 340 million people.
- The population in metro areas also grew faster from 2023 to 2024 than between 2022 and 2023 (when it increased by 0.9% or 2.6 million people) largely due to higher levels of net international migration.
- The population in nearly 90% (341 of 387) of U.S. metro areas grew from 2023 to 2024, up from 317 between 2022 and 2023.
- The collective increase in population across metro areas was largely attributable to net international migration — approximately 2.7 million, with an additional 0.6 million from natural increase (excess of births over deaths).
- Some metro areas that experienced population declines earlier in the decade, such as New York-Newark-Jersey City, NY-NJ, Washington-Arlington-Alexandria, DC-VA-MD-WV, and San Francisco-Oakland-Fremont, CA, experienced population gains from 2023 to 2024.
County Highlights
Nearly two-thirds (65.3%) of the 3,144 counties in the 50 states and the District of Columbia grew last year. In general, large counties had faster growth in 2024, while small counties noted more population loss.
Large counties (those with populations over 100,000 in 2024) grew on average by 1.1%, up from 1.0% in 2023. Conversely, among the 737 smallest counties with populations below 10,000, the average annual decrease was 0.2% in 2024, compared to a 0.1% decrease from 2022 to 2023.
- In 2024, the average percent change for counties was just under 0.4 while the average numeric change was 1,051.
- Nine of the 10 largest-gaining counties were located in large metro areas in the South and West.
- In the 2,054 counties that grew last year, growth largely stemmed from international migration, as natural decrease (more deaths than births) remained prevalent in many parts of the country.

Metropolitan and Micropolitan Statistical Areas
- In 2024, 86.4% of the U.S. population lived in metro areas.
- Metro areas as a whole increased by nearly 3.2 million from 2023 to 2024, accounting for 96% of the nation’s total population growth.
- Roughly 60% of individual metro areas experienced natural increase and approximately 59% had net domestic in-migration (although U.S. metro areas overall experienced net domestic outmigration).
- Of the 10 fastest-growing metro areas between 2023 and 2024, nine were in the South, while one was in the West, with the two fastest growing being located in Florida.
- Seven of the 10 fastest-growing micro areas were in the South, with the two fastest growing over the period located in Georgia and Florida.

Technical Notes
The most recent net international migration estimates reflect methodological improvements, which included the incorporation of additional administrative data. Details are available in the Random Samplings blog, “Census Bureau Improves Methodology to Better Capture Increase in Net International Migration.”
In May, the Census Bureau is scheduled to release estimates of the July 1, 2024, population for cities and towns (incorporated places and minor civil divisions). The data will be embargoed. The full release schedule for the Population Estimates Program can be found on the Census Bureau’s website.
With each new release of annual estimates, the entire time series of estimates is revised for all years back to the date of the last census. All previously published estimates (i.e., old vintages) are superseded and archived on the FTP2 site. Due to periodic methodological updates, such as this year’s immigration adjustment, year-to-year comparisons in the estimates should only be done within the same vintage.
