South River, NM population, income and ZIP codes

South River CDP is a small town in New Mexico, with 1,594 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #110 of 527 ranked by population — larger than 79% of them. The median age here is 56.5 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 South River CDP earn a median of $56,307 a year, 28.3% below the national figure of $78,538 and 4% above the $54,029 median for the 153 New Mexico cities we cover. 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 14.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in South River CDP is valued at $215,000, 29.1% below the national figure and 13% above the $190,000 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 92.4% 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 56.5 puts South River 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.

The Census withheld gross rent for South River CDP 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.
