Texas has no state income tax, saving the local median household (AGI $64,091) approximately $2,948/year vs the US average effective state tax rate. IRS migration data (2022-2023) shows a net gain of 568 residents (270 households) — the ZIP's primary county is growing. Healthcare access is the area's quieter strength; school options sit on the lighter side, so families may find themselves looking at districts a few ZIPs over. Notable: median household income $83,438, fair market rent of $1,140 for a two-bedroom, and a typical home value of $270,245, down 4.8% over the past year. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.
The two domains pull in different directions. Healthcare access reads strong, but the on-paper school count is on the lighter side — that’s less a quality signal and more a density one. Households here often look at districts a few ZIPs over for school choice while keeping their providers local.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 23.8%. Each figure on this page links to the original federal dataset with its retrieval date — this synthesis is a reading, not a substitute for the underlying records.

The Social Vulnerability Index uses U.S. Census data to identify communities most at risk during public health emergencies and natural disasters. Higher percentiles indicate greater vulnerability. Tract-level scores are aggregated to this ZCTA via Census 2020 ZCTA→Tract crosswalk, weighted by land-area share. Source: atsdr.cdc.gov. Public domain.
