Oakland County Gains Population, But Not Without Some Context
(Kurt Metzger, March 27, 2026)
Oakland County, MI – The Census Bureau has released its 2025 population estimates for counties, metropolitan and micropolitan areas. The story is another year of population growth for Oakland County, but the increase is lower than expected.
To develop the estimates, the Census Bureau uses four demographic components – births, deaths, immigration, and domestic migration. A base year population is established, and then the total of those four components is calculated (positive or negative) to develop the household population total, and those living in group quarters are added in.
In addition to this calculation each year, the Census Bureau also looks back at previous years and makes adjustments based on the newest information.
While preparing the 2025 estimate, the Bureau made adjustments to the 2022, 2023, and 2024 totals. In those years, immigrant population estimates were higher than the actual numbers ended up being.
In Oakland County, they had estimated an increase of 42,178 immigrants for 2022-24. But with the new revisions, that total is just 29,150 – over 13,000 fewer immigrant residents than expected.
The 2025 estimates include an immigration number of 7,688, about two-thirds of the total in previous years.
When the final calculations were made, 2025’s population was 1,288,237, a gain of 5,788 residents over 2024’s revised population, but 8,551 below last year’s published estimate at the time.
So while the overall population is increasing, it is not increasing as quickly as previously expected.
Between 2020 and 2025, Oakland County had 64,894 births and 62,775 deaths, lost 28,050 to domestic outmigration, and gained 38,982 immigrants.
The population growth is mainly driven by immigration being stronger than outmigration, but that gap is closing. Anti-immigrant Federal policies and cultural sentiments, along with economic opportunities are factors that Michigan, and Oakland County, need to consider if we are to keep building a strong workforce and tax base, as well as a culturally-diverse environment.
Of the 83 counties in Michigan, 47 of them, including Oakland, saw increased populations. But overall the state’s gain was only 0.6%.
Oakland County’s 5,788 resident increase had the highest number of people, and accounted for 0.45% of an increase.
Nearby, Wayne County’s increase was 0.2%. Monroe was 0.09%. Lapeer was 0.27%. And Genesse County’s population declined by 0.05%.
Celebrating the increases makes sense, but we must also keep in mind longer-term trends and the overall population needs.
