The median age here is not published.

Households in ZIP 88421 earn a median of not published a year. 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 0% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 88421 is valued at not published, while median gross rent runs not published a month. 0% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
With 22 residents, a handful of survey responses moves every median on this page. Compare ZIP 88421 against its county rather than against national figures.
The Census withheld household income, home value, gross rent for ZIP 88421 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 88421 in context
How 88421 sits inside San Miguel County and New Mexico.
ZIP 88421 is tabulated inside San Miguel County, New Mexico, one of 17 ZIP areas the Census publishes for that county and 372 across New Mexico. 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 88421 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 88421 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.
New Mexico charges 4.875% statewide, and local governments overlapping 88421 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 88421 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.
