South Tucson, AZ population, income and ZIP codes

South Tucson city is a small town in Arizona, with 4,601 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #102 of 467 ranked by population — larger than 78% of them. The median age here is 36.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 Tucson city earn a median of $33,734 a year, 57% below the national figure of $78,538 and 47% below the $63,545 median for the 206 Arizona 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 35.2% 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 South Tucson city is valued at $152,300, 49.8% below the national figure and 37% below the $242,700 peer median, while median gross rent runs $968 a month, 31.2% below the national figure, or roughly $11,616 across a full year. A household on the local median income would put about 34.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 4.5×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 31.9% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
