ZIP code 78703

ZIP 78703 is a mid-size town in Travis County, Texas, with 22,484 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #529 of 1,989 ranked by population — larger than 73% of them. The median age here is 40.9 years against 39.1 nationally, a slightly older 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 78703 earn a median of $144,637 a year, 84.2% above the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 5.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in ZIP 78703 is valued at $1,353,500, 346.1% above the national figure, while median gross rent runs $2,217 a month, 57.7% above the national figure, or roughly $26,604 across a full year. A household on the local median income would put about 18.4% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 9.4×, 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. 52.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 9.4× 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.

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 78703 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 mid-sized suburban ZIP inside a county that is split across many delivery areas. 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 78703 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 78703 reports a median household income of $144,637, 41% above the $102,799 county median, and 112% above the $68,103 typical TX ZIP. Owner-occupied homes are valued at a median of $1,353,500, 150% above the county figure and 594% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $2,217 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 78703 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 78703 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 78703 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.
