Fairfield city, IA in context

How this area compares with national benchmarks.

Fairfield city is a mid-size town in Iowa, with 9,438 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #45 of 1,026 ranked by population — larger than 95% of them. The median age here is 40.5 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 Fairfield city earn a median of $48,302 a year, 38.5% below the national figure of $78,538 and 29% below the $67,791 median for the 290 Iowa 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 19.2% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Fairfield city is valued at $152,900, 49.6% below the national figure and within a couple of points of the $156,300 peer median, while median gross rent runs $864 a month, 38.5% below the national figure, or roughly $10,368 across a full year. A household on the local median income would put about 21.5% 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 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 56.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
