ZIP 50315 in context

How this area compares with national benchmarks.

ZIP 50315 is a small city in Polk County, Iowa, with 35,349 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #12 of 970 ranked by population — larger than 98% of them. The median age here is 36.8 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 50315 earn a median of $62,036 a year, 21% 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 13.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 50315 is valued at $164,000, 45.9% below the national figure, while median gross rent runs $977 a month, 30.5% below the national figure, or roughly $11,724 across a full year. A household on the local median income would put about 18.9% 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 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 61.2% 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.

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 50315 in context

How 50315 sits inside Polk County and Iowa.

ZIP 50315 is tabulated inside Polk County, Iowa, one of 33 ZIP areas the Census publishes for that county and 970 across Iowa. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. 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 50315 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 50315 reports a median household income of $62,036, 31% below the $89,323 county median, and 13% below the $71,182 typical IA ZIP. Owner-occupied homes are valued at a median of $164,000, 39% below the county figure and 8% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $977 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 50315 carries 7% at the register, assembled from the Des Moines jurisdiction stack: the Iowa state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 50315 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

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 50315 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.

A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
