St. Ignace, MI population, income and ZIP codes

St. Ignace city is a small town in Michigan, with 2,409 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #274 of 745 ranked by population — larger than 63% of them. The median age here is 48.1 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 St. Ignace city earn a median of $60,735 a year, 22.7% 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. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 22.5% 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 St. Ignace city is valued at $127,800, 57.9% below the national figure and 23% below the $166,100 peer median, while median gross rent runs $620 a month, 55.9% below the national figure, or roughly $7,440 across a full year. A household on the local median income would put about 12.2% 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 2.1×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 63.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

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.
