San Carlos, AZ population, income and ZIP codes

San Carlos CDP is a small town in Arizona, with 4,769 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #99 of 467 ranked by population — larger than 78% of them. The median age here is 28.4 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Carlos CDP earn a median of $50,814 a year, 35.3% below the national figure of $78,538 and 20% below the $63,545 median for the 206 Arizona cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 44.2% 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 Carlos CDP is valued at $67,700, 77.7% below the national figure and 72% below the $242,700 peer median, while median gross rent runs $397 a month, 71.8% below the national figure, or roughly $4,764 across a full year. A household on the local median income would put about 9.4% 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 1.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 57.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 28.4 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

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.
