ZIP 78590 in context

How this area compares with national benchmarks.

ZIP 78590 is a very small community in Willacy County, Texas, with 449 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1631 of 1,989 ranked by population — larger than 18% of them. The median age here is 31.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 78590 earn a median of $77,750 a year, 1% below the national figure of $78,538. 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 17.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 78590 is valued at $54,500, 82% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 0.7×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 100% 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.

With 449 residents, a handful of survey responses moves every median on this page. Compare ZIP 78590 against its county rather than against national figures.

The Census withheld gross rent for ZIP 78590 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 78590 in context

How 78590 sits inside Willacy County and Texas.

ZIP 78590 is tabulated inside Willacy County, Texas, one of 6 ZIP areas the Census publishes for that county and 1,989 across Texas. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. 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 78590 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 78590 reports a median household income of $77,750, 76% above the $44,217 county median, and 14% above the $68,103 typical TX ZIP. Owner-occupied homes are valued at a median of $54,500, close to the county figure and 72% 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.

Texas charges 6.25% statewide, and local governments overlapping 78590 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 78590 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.
