San Ysidro CDP, NM population, income and ZIP codes

San Ysidro CDP is a small town in New Mexico, with 2,179 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #84 of 527 ranked by population — larger than 84% of them. The median age here is 58.7 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 San Ysidro CDP earn a median of $90,724 a year, 15.5% above the national figure of $78,538 and 68% above the $54,029 median for the 153 New Mexico cities we cover. 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 15.9% of residents here, above the 12.4% national rate.

The typical owner-occupied home in San Ysidro CDP is valued at $306,900, 1.2% above the national figure and 62% above the $190,000 peer median, while median gross rent runs $931 a month, 33.8% below the national figure, or roughly $11,172 across a full year. A household on the local median income would put about 12.3% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.7% 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. 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 58.7 puts San Ysidro CDP 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. 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.

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.
