Au Sable, MI population, income and ZIP codes

Au Sable CDP is a small town in Michigan, with 1,780 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #331 of 745 ranked by population — larger than 55% of them. The median age here is 45.8 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 Au Sable CDP earn a median of $46,369 a year, 41% below the national figure of $78,538 and 25% below 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 13.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Au Sable CDP is valued at $107,900, 64.4% below the national figure and 35% below the $166,100 peer median, while median gross rent runs $914 a month, 35% below the national figure, or roughly $10,968 across a full year. A household on the local median income would put about 23.7% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.3×, 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. 87% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
