ZIP 85645 in context
How this area compares with national benchmarks.
ZIP 85645 is a small town in Pima County, Arizona, with 1,317 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #324 of 417 ranked by population — larger than 22% of them. The median age here is 60.3 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 ZIP 85645 earn a median of $65,266 a year, 16.9% below the national figure of $78,538. 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 4.1% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 85645 is valued at $220,000, 27.5% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 91.7% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
A median age of 60.3 puts ZIP 85645 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 ZIP 85645 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.
Reading ZIP 85645 in context
How 85645 sits inside Pima County and Arizona.
ZIP 85645 is tabulated inside Pima County, Arizona, one of 51 ZIP areas the Census publishes for that county and 417 across Arizona. Fewer than 2,500 people are counted here, so the ZIP behaves like a village delivery route rather than a neighbourhood. 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 85645 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 85645 reports a median household income of $65,266, 4% below the $68,062 county median, and close to the $64,475 typical AZ ZIP. Owner-occupied homes are valued at a median of $220,000, 18% below the county figure and 23% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.
Arizona charges 5.6% statewide, and local governments overlapping 85645 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.
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 85645 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.
Sales tax in 85645
What a purchase inside this ZIP costs at checkout.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
