ZIP code 50103

ZIP 50103 is a very small community in Decatur County, Iowa, with 398 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #735 of 970 ranked by population — larger than 24% of them. The median age here is 41.4 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 50103 earn a median of $62,500 a year, 20.4% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 16.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 50103 is valued at $90,000, 70.3% below the national figure, while median gross rent runs $650 a month, 53.8% below the national figure, or roughly $7,800 across a full year. A household on the local median income would put about 12.5% 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 1.4×, 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. 89.4% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

With 398 residents, a handful of survey responses moves every median on this page. Compare ZIP 50103 against its county rather than against national figures.

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.

ZIP 50103 is tabulated inside Decatur County, Iowa, one of 7 ZIP areas the Census publishes for that county and 970 across Iowa. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. 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 50103 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 50103 reports a median household income of $62,500, 22% above the $51,111 county median, and 12% below the $71,182 typical IA ZIP. Owner-occupied homes are valued at a median of $90,000, close to the county figure and 41% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $650 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 50103 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 50103 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.
