Frankenmuth, MI population, income and ZIP codes

Frankenmuth city is a mid-size town in Michigan, with 5,108 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #178 of 745 ranked by population — larger than 76% of them. The median age here is 51.8 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Frankenmuth city earn a median of $84,583 a year, 7.7% above the national figure of $78,538 and 37% 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 3.6% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Frankenmuth city is valued at $277,600, 8.5% below the national figure and 67% above the $166,100 peer median, while median gross rent runs $814 a month, 42.1% below the national figure, or roughly $9,768 across a full year. A household on the local median income would put about 11.5% 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 3.3×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 69.1% 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.

A median age of 51.8 puts Frankenmuth city well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

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.
