ZIP 58638 in context

How this area compares with national benchmarks.

ZIP 58638 is a very small community in Morton County, North Dakota, with 949 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #102 of 389 ranked by population — larger than 73% of them. The median age here is 42 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 58638 earn a median of $60,341 a year, 23.2% 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 8.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 58638 is valued at $111,700, 63.2% below the national figure, while median gross rent runs $869 a month, 38.2% below the national figure, or roughly $10,428 across a full year. A household on the local median income would put about 17.3% 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 1.9×, 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. 77.9% 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.

With 949 residents, a handful of survey responses moves every median on this page. Compare ZIP 58638 against its county rather than against national figures.

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.

Reading ZIP 58638 in context

How 58638 sits inside Morton County and North Dakota.

ZIP 58638 is tabulated inside Morton County, North Dakota, one of 8 ZIP areas the Census publishes for that county and 389 across North Dakota. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 58638 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 58638 reports a median household income of $60,341, 21% below the $76,250 county median, and 23% below the $78,594 typical ND ZIP. Owner-occupied homes are valued at a median of $111,700, 13% below the county figure and 30% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $869 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

North Dakota charges 5% statewide, and local governments overlapping 58638 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 58638 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.
