Trenton, MI population, income and ZIP codes

Trenton city is a mid-size town in Michigan, with 18,242 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #64 of 745 ranked by population — larger than 91% of them. The median age here is 48.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Trenton city earn a median of $78,565 a year, essentially level with the national figure of $78,538 and 27% above the $61,715 median for the 438 Michigan cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 7.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Trenton city is valued at $202,400, 33.3% below the national figure and 22% above the $166,100 peer median, while median gross rent runs $873 a month, 37.9% below the national figure, or roughly $10,476 across a full year. A household on the local median income would put about 13.3% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 83% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
