ZIP code 48109

ZIP 48109 is a mid-size town in Washtenaw County, Michigan, with 5,722 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #446 of 992 ranked by population — larger than 55% of them. The median age here is 19.1 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 ZIP 48109 earn a median of not published a year. 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 98.8% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 48109 is valued at not published, while median gross rent runs not published a month. 0% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 19.1 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld household income, home value, gross rent for ZIP 48109 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency.
