ZIP 50131 in context

How this area compares with national benchmarks.

ZIP 50131 is a mid-size town in Polk County, Iowa, with 24,388 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #33 of 970 ranked by population — larger than 96% of them. The median age here is 38.5 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 ZIP 50131 earn a median of $103,316 a year, 31.5% above 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 7.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 50131 is valued at $347,100, 14.4% above the national figure, while median gross rent runs $1,284 a month, 8.7% below the national figure, or roughly $15,408 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 72.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

Reading ZIP 50131 in context

How 50131 sits inside Polk County and Iowa.

ZIP 50131 is tabulated inside Polk County, Iowa, one of 33 ZIP areas the Census publishes for that county and 970 across Iowa. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 50131 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 50131 reports a median household income of $103,316, 16% above the $89,323 county median, and 45% above the $71,182 typical IA ZIP. Owner-occupied homes are valued at a median of $347,100, 30% above the county figure and 129% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,284 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Iowa charges 6% statewide, and local governments overlapping 50131 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 50131 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
