ZIP code 80421

ZIP 80421 is a mid-size town in Park County, Colorado, with 8,601 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #187 of 528 ranked by population — larger than 64% of them. The median age here is 49 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 80421 earn a median of $105,617 a year, 34.5% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 6.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 80421 is valued at $552,400, 82.1% above the national figure, while median gross rent runs $2,235 a month, 59% above the national figure, or roughly $26,820 across a full year. A household on the local median income would put about 25.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 5.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 90.7% 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.

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.

Colorado charges 2.9% statewide, and local governments overlapping 80421 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 80421 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.
