Clay County, IA in context
How this area compares with national benchmarks.
Clay County is a mid-size town in Iowa, with 16,446 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 41.8 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 Clay County earn a median of $64,082 a year, 18.4% below the national figure of $78,538. 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 11.5% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Clay County is valued at $171,500, 43.5% below the national figure, while median gross rent runs $798 a month, 43.2% below the national figure, or roughly $9,576 across a full year. A household on the local median income would put about 14.9% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 72.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
