ZIP 81638 in context

How this area compares with national benchmarks.

ZIP 81638 is a very small community in Moffat County, Colorado, with 94 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #484 of 528 ranked by population — larger than 8% of them. The median age here is 65.8 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 81638 earn a median of not published a year. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 29.8% 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 ZIP 81638 is valued at not published, while median gross rent runs not published a month. 86.4% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 65.8 puts ZIP 81638 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 94 residents, a handful of survey responses moves every median on this page. Compare ZIP 81638 against its county rather than against national figures.

The Census withheld household income, home value, gross rent for ZIP 81638 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

Reading ZIP 81638 in context

How 81638 sits inside Moffat County and Colorado.

ZIP 81638 is tabulated inside Moffat County, Colorado, one of 5 ZIP areas the Census publishes for that county and 528 across Colorado. 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 81638 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 81638 reports a median household income of not published. Owner-occupied homes are valued at a median of not published. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Colorado charges 2.9% statewide, and local governments overlapping 81638 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 81638 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.
