San Juan ZIP codes — San Juan County, New Mexico

San Juan County is a mid-size city in New Mexico, with 121,178 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 38 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in San Juan County earn a median of $53,020 a year, 32.5% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 23.2% 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 San Juan County is valued at $185,100, 39% below the national figure, while median gross rent runs $917 a month, 34.8% below the national figure, or roughly $11,004 across a full year. A household on the local median income would put about 20.8% 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 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 70.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
