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.

What these numbers say together
Big Wells, TX (ZIP 78830) sits in Dimmit County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Health Insurance comes in above the national average at 45.4%. No NCES schools are mapped to this ZIP in the current dataset. 4 colleges and universities serve the area, with median in-state tuition of $2,646. 38% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. BLS LAUS records a 6.8% county unemployment rate (2024) — about 2.8 points above the US average and a labor-market distress signal. CDC's Social Vulnerability Index places this ZIP in the 98th percentile nationally — a highly vulnerable community profile. FEMA has issued 17 federal disaster declarations affecting this ZIP since 1984. County Health Rankings reports 14,362 years of potential life lost per 100,000 (2025) — well above the national county median. Per USDA's Food Environment Atlas, 53.9% of residents in this county live more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket — a deep food-access gap. Texas has no state income tax, saving the local median household (AGI $56,376) approximately $2,593/year vs the US average effective state tax rate. IRS migration data (2022-2023) shows a net loss of 66 residents (32 households) — the ZIP's primary county is shrinking. 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 $32,188, fair market rent of $970 for a two-bedroom, and a typical home value of $95,609, up 18.9% 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.
Both surfaces skew lighter than national averages. That isn’t a verdict — small-area estimates compress real neighborhood-level texture, and a single ZIP reading can miss a district line or a hospital corridor sitting just outside it. Treat this as a starting point for fieldwork, not a conclusion.
- Fair market rent for a two-bedroom ($970/month, HUD SAFMR) represents 36% of median household income ($32,188, Census ACS) — above the 30% affordability threshold commonly used by housing experts.
- Lower median household income ($32,188, Census ACS) sits alongside an above-average 46.6% obesity rate (CDC PLACES) — a pattern that correlates with reduced healthcare access in lower-income areas.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 20.3%. 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.
