Williamston city, MI in context

How this area compares with national benchmarks.

Williamston city is a small town in Michigan, with 3,800 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #215 of 745 ranked by population — larger than 71% of them. The median age here is 40 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Williamston city earn a median of $73,902 a year, 5.9% below the national figure of $78,538 and 20% above the $61,715 median for the 438 Michigan cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Williamston city is valued at $215,000, 29.1% below the national figure and 29% above the $166,100 peer median, while median gross rent runs $972 a month, 30.9% below the national figure, or roughly $11,664 across a full year. A household on the local median income would put about 15.8% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 73.4% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
