Mackinac Island, MI population, income and ZIP codes

Mackinac Island city is a very small community in Michigan, with 663 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #502 of 745 ranked by population — larger than 32% of them. The median age here is 39.8 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 Mackinac Island city earn a median of $100,125 a year, 27.5% above the national figure of $78,538 and 62% above 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 17.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Mackinac Island city is valued at $834,600, 175.1% above the national figure and 402% above the $166,100 peer median, while median gross rent runs $1,164 a month, 17.2% below the national figure, or roughly $13,968 across a full year. A household on the local median income would put about 14% 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 8.3×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 48.5% 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.

Home values sit at 8.3× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
