St. Johns city, MI in context

How this area compares with national benchmarks.

St. Johns city is a mid-size town in Michigan, with 7,712 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #131 of 745 ranked by population — larger than 82% of them. The median age here is 43.5 years against 39.1 nationally, a slightly older profile than the country as a whole. 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 St. Johns city earn a median of $63,030 a year, 19.7% below the national figure of $78,538 and within a couple of points of the $61,715 median for the 438 Michigan cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 13.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in St. Johns city is valued at $175,300, 42.2% below the national figure and 6% above the $166,100 peer median, while median gross rent runs $870 a month, 38.1% below the national figure, or roughly $10,440 across a full year. A household on the local median income would put about 16.6% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 67.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.
