Chambers County · Houston-Pasadena-The Woodlands, TX · Population 27,489
Mont Belvieu, TX (ZIP 77523) sits in Chambers County within the Houston-Pasadena-The Woodlands metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Annual Checkup comes in above the national average at 72.0%. No NCES schools are mapped to this ZIP in the current dataset. 10 colleges and universities serve the area, with median in-state tuition of $2,505. IRS data shows average household income (AGI) of $106,364, well above the ~$45K national average per return. FEMA has issued 43 federal disaster declarations affecting this ZIP since 1973 — a high-frequency exposure profile. Fast-food restaurants outnumber grocery stores roughly 7-to-1 per capita (USDA Food Environment Atlas) — a "food swamp" pattern often linked to higher diet-related disease prevalence. IRS migration data (2022-2023) shows a net gain of 1,476 residents (666 households) — the ZIP's primary county is growing. Both healthcare access and on-paper school density skew lighter than national norms; what shows up here is a snapshot, not a verdict — neighborhood-level texture matters at this scale. Notable: median household income $131,444, fair market rent of $1,590 for a two-bedroom, and a typical home value of $375,894, up 1.7% 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 higher the national rate at 24.1%. 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.
