Decatur city, IN in context
How this area compares with national benchmarks.
Decatur city is a mid-size town in Indiana, with 9,769 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #88 of 976 ranked by population — larger than 91% of them. The median age here is 43.6 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 Decatur city earn a median of $58,867 a year, 25% below the national figure of $78,538 and 4% below the $61,527 median for the 355 Indiana 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 10.8% of residents here, below the 12.4% national rate.
The typical owner-occupied home in Decatur city is valued at $132,900, 56.2% below the national figure and 9% below the $145,600 peer median, while median gross rent runs $804 a month, 42.8% below the national figure, or roughly $9,648 across a full year. A household on the local median income would put about 16.4% 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 2.3×, 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. 73.1% 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.
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.
