San Tan Valley, AZ population, income and ZIP codes

San Tan Valley CDP is a mid-size city in Arizona, with 105,231 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #11 of 467 ranked by population — larger than 97% of them. The median age here is 35 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 Tan Valley CDP earn a median of $93,642 a year, 19.2% above the national figure of $78,538 and 47% above the $63,545 median for the 206 Arizona 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 7.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in San Tan Valley CDP is valued at $365,900, 20.6% above the national figure and 51% above the $242,700 peer median, while median gross rent runs $1,857 a month, 32.1% above the national figure, or roughly $22,284 across a full year. A household on the local median income would put about 23.8% 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 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 81.6% 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.

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.
