Katy, TX is covered by 4 USPS ZIP codes serving a combined population of 250,975 according to Census ACS 5-Year Estimates. U.S. cities rarely map cleanly to a single ZIP — Katy splits its residents across 4 delivery areas, each with its own demographic and housing profile. The table below lists every ZIP by population, so you can see which neighborhoods carry the weight of the city total and which are smaller pockets of the same municipal boundary.
Aggregated across every ZIP in Katy, the median household income averages $115,349 and per-capita income averages $44,856. Poverty rate runs at 9.0% and unemployment at 5.7%. On housing, the average median home value is $362,900 with median rent of $1,911 per month, and 71.9% of occupied units are owner-occupied. These are arithmetic averages across the 4 ZIPs — not population-weighted — so small ZIPs influence the headline numbers the same as large ones.

The Affordability Dashboard linked below combines these Census inputs with HUD Fair Market Rents, FBI crime data, and Department of Labor childcare costs into a graded scorecard for Katy as a whole, while individual ZIP pages show fine-grained household income, housing profile, education attainment, commute time, and nearby-ZIP benchmarks. Every field on this page is sourced directly from U.S. Census Bureau ACS 2023 5-Year Estimates — no estimates, no proprietary scoring, no editorial adjustment.
