ZIP 81331 in context

How this area compares with national benchmarks.

ZIP 81331 is a very small community in Montezuma County, Colorado, with 423 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #406 of 528 ranked by population — larger than 23% of them. The median age here is 24.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 81331 earn a median of $81,000 a year, 3.1% 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 17.7% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 81331 is valued at $346,800, 14.3% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 4.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 100% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 24.9 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

The Census withheld gross rent for ZIP 81331 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 81331 in context

How 81331 sits inside Montezuma County and Colorado.

ZIP 81331 is tabulated inside Montezuma County, Colorado, one of 7 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 81331 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 81331 reports a median household income of $81,000, 11% above the $72,993 county median, and close to the $80,917 typical CO ZIP. Owner-occupied homes are valued at a median of $346,800, 5% below the county figure and 19% below the statewide ZIP median. 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 81331 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 81331 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.
