ZIP code 78704

ZIP 78704 is a small city in Travis County, Texas, with 50,479 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #134 of 1,989 ranked by population — larger than 93% of them. The median age here is 34.2 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 78704 earn a median of $97,160 a year, 23.7% above 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 11.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 78704 is valued at $862,000, 184.1% above the national figure, while median gross rent runs $1,755 a month, 24.8% above the national figure, or roughly $21,060 across a full year. A household on the local median income would put about 21.7% 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 8.9×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 33.2% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Home values sit at 8.9× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

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.

ZIP 78704 is tabulated inside Travis County, Texas, one of 48 ZIP areas the Census publishes for that county and 1,989 across Texas. 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 78704 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 78704 reports a median household income of $97,160, 5% below the $102,799 county median, and 43% above the $68,103 typical TX ZIP. Owner-occupied homes are valued at a median of $862,000, 59% above the county figure and 342% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,755 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 78704 carries 8.25% at the register, assembled from the Austin jurisdiction stack: the Texas 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 78704 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 78704 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.
