Metro Detroit's modest population gains are flattening as immigration falls nationwide, new Census data shows.
Why it matters: Any local population increase is welcome after decades of decline.
Between the lines: The new data offers the best look yet at how tighter immigration enforcement is affecting America's demographic makeup.
Driving the news: Wayne, Macomb and Oakland counties each saw population growth of less than 1% between 2024 and 2025, the Census Bureau says.
Context: Counties in the top 10 for population growth, mostly in southern states, saw increases between 4% and 6%.
The big picture: Michigan has eked out small population gains in recent years after prolonged stagnation, with new immigrants driving much of that growth.
- The latest Census data suggests that momentum may be slowing again, with Metro Detroit reflecting that broader plateau.
By the numbers: Michigan's population was 10,127,884 as of July, up 0.3% (or 27,922 people) from July 2024.
- Wayne County's population was 1.8 million, up 0.2%.
- Macomb County had about 886,000 residents, a 0.4% increase.
- Oakland County's population was 1.3 million, up 0.5%.
Zoom out: International migration fell in 90% of U.S. counties between 2024 and 2025 compared to the prior period, per the Census Bureau.
- Other counties stayed flat.
What they're saying: That drop is hitting populous areas especially hard.
- In a statement, Census Bureau demographer George M. Hayward said: "The nation's largest counties ... are often international migration hubs, gaining large numbers of international migrants and losing people that move to other parts of the country via domestic migration."
- "With fewer gains from international migration, these types of counties saw their population growth diminish or even turn into loss."
Yes, but: The U.S. overall still grew by 0.5% between 2024 and 2025.
- But that's down from 1% over the previous period.
Nationwide natural change (births minus deaths) held steady, while international migration plummeted from about 2.8 million people to 1.3 million — about a 55% drop.
Caveat: The Census' international migration data includes both foreigners and Americans coming home from abroad, including military service members.
