Iron Mountain, MI population, income and ZIP codes

Iron Mountain city is a mid-size town in Michigan, with 7,508 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #138 of 745 ranked by population — larger than 81% of them. The median age here is 42.9 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 Iron Mountain city earn a median of $56,622 a year, 27.9% below the national figure of $78,538 and 8% below 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 11.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Iron Mountain city is valued at $117,600, 61.2% below the national figure and 29% below the $166,100 peer median, while median gross rent runs $656 a month, 53.3% below the national figure, or roughly $7,872 across a full year. A household on the local median income would put about 13.9% 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. 72.6% 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.
