In late March of 2026, the United States Census Bureau released its population estimates for metropolitan areas.
The data show that the D.C. metro area’s population grew by less than 1 percent in 2025, down from almost 1.4 percent in 2024. Lower migration rates drove the slowdown—especially from abroad. International migration fell from nearly 12.7 per 1,000 people to 7 per 1,000, while domestic outmigration remained steady at about 3.7 per 1,000.
In 2025, death rates hovered slightly above 6 per 1,000 people, while birth rates were almost 11 per 1,000 people. The longer-term birth trend, however, is concerning. Since 2022, birth rates in the D.C. region have declined, mirroring trends across many other metropolitan areas and the District itself—suggesting a broader fertility decline that extends beyond any single city.
Nevertheless, fewer births will negatively affect enrollment in public schools. In the District proper, for example, research by the D.C. Policy Center’s Education Policy Initiative suggests that fewer births could lead to a loss of 743 enrolled students over the next half decade. Much of the decline in enrollment would affect pre-kindergarten, where enrollment could fall by 14 percent.
Birth trends contribute to the broader pattern of slower population growth in high-cost metro areas. While the D.C. metro area ranked second compared to its higher-cost peers, higher-cost metro areas underperformed their lower-cost counterparts. For example, the D.C. metro area ranked in the bottom half of lower-cost metro areas.
In sum, the 2025 metro estimates show that population growth in the D.C. metro area remains fragile and lags many lower-cost metro areas across the country. Future growth likely hinges on migration flows, which can shift quickly, and birth rates, which have shown few signs of rebounding.
