Mahaska County, IA in context

How this area compares with national benchmarks.

Mahaska County is a mid-size town in Iowa, with 22,045 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 39.1 years against 39.1 nationally, a slightly younger 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 Mahaska County earn a median of $69,019 a year, 12.1% below the national figure of $78,538. 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 11.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Mahaska County is valued at $140,900, 53.6% below the national figure, while median gross rent runs $821 a month, 41.6% below the national figure, or roughly $9,852 across a full year. A household on the local median income would put about 14.3% 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×, 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. 67.8% 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.

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.

How to read this page

What these estimates cover.

Figures are five-year rolling averages from the American Community Survey, not single-year counts, so they describe conditions across 2019-2023 ACS 5-year rather than a single date. Median home value covers owner-occupied units as valued by their owners, and median gross rent includes utilities the renter pays. Small counties carry wide margins of error; treat single-dollar differences between neighbouring counties as noise.
