ZIP 77856 in context

How this area compares with national benchmarks.

ZIP 77856 is a small town in Robertson County, Texas, with 4,832 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1026 of 1,989 ranked by population — larger than 48% of them. The median age here is 37.1 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 77856 earn a median of $90,889 a year, 15.7% 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 8.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 77856 is valued at $245,900, 19% below the national figure, while median gross rent runs $919 a month, 34.6% below the national figure, or roughly $11,028 across a full year. A household on the local median income would put about 12.1% 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 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 74.7% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.

Reading ZIP 77856 in context

How 77856 sits inside Robertson County and Texas.

ZIP 77856 is tabulated inside Robertson County, Texas, one of 6 ZIP areas the Census publishes for that county and 1,989 across Texas. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 77856 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 77856 reports a median household income of $90,889, 31% above the $69,423 county median, and 33% above the $68,103 typical TX ZIP. Owner-occupied homes are valued at a median of $245,900, 53% above the county figure and 26% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $919 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 77856 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 77856 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.
