ZIP code 85203

ZIP 85203 is a small city in Maricopa County, Arizona, with 37,435 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #82 of 417 ranked by population — larger than 80% of them. The median age here is 33.3 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 85203 earn a median of $72,851 a year, 7.2% below the national figure of $78,538. 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 12% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 85203 is valued at $388,300, 28% above the national figure, while median gross rent runs $1,388 a month, 1.3% below the national figure, or roughly $16,656 across a full year. A household on the local median income would put about 22.9% 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 5.3×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 56.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.

ZIP 85203 is tabulated inside Maricopa County, Arizona, one of 135 ZIP areas the Census publishes for that county and 417 across Arizona. This is a dense urban ZIP, where a single postal boundary can hold more residents than an entire rural county. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 85203 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 85203 reports a median household income of $72,851, 11% below the $81,990 county median, and 13% above the $64,475 typical AZ ZIP. Owner-occupied homes are valued at a median of $388,300, 3% below the county figure and 35% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,388 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 85203 carries 8.3% at the register, assembled from the Mesa jurisdiction stack: the Arizona state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 85203 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 85203 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
