Hays County · Austin-Round Rock-San Marcos, TX · Population 24,951
Belterra, TX (ZIP 78737) sits in Hays County within the Austin-Round Rock-San Marcos metro area. The page draws on 2 federal data feeds retrieved Apr 24. Top health signal: Health Insurance comes in below the national average at 7.3%. NCES lists 4 schools serving the area, 4 non-charter. 10 colleges and universities serve the area, with median in-state tuition of $23,500. IRS data shows average household income (AGI) of $212,006, well above the ~$45K national average per return. FDIC counts just 1 bank branch in this ZIP (Summary of Deposits, 2024) — residents likely lean on neighboring ZIPs or online banking for most services. Social vulnerability is low in this ZIP at the 19th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 44 federal disaster declarations affecting this ZIP since 1970 — a high-frequency exposure profile. Fast-food restaurants outnumber grocery stores roughly 12-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 7,077 residents (3,587 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 $151,635, fair market rent of $2,480 for a two-bedroom, and a typical home value of $779,515, down 3.5% 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 21.3%. 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.
