Upton County · Population 1,202
Fresh.Data current as of Apr 23, 2026
Rankin, TX (ZIP 79778) sits in Upton County. The page draws on 2 federal data feeds retrieved Apr 24. Top health signal: Health Insurance comes in above the national average at 18.7%. NCES lists 1 schools serving the area, 1 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $2,766. Average annual pay across local establishments runs $82,368 per worker (Census ZBP) — a high-wage local economy. BLS QCEW puts average annual pay at $87,660 per worker — about 34% above the US average and a clear high-wage signal. BLS LAUS reports county unemployment of just 1.7% (2024), well below the ~4.0% US average and consistent with a tight local labor market. 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. FEMA has issued 13 federal disaster declarations affecting this ZIP since 1993. Annual precipitation averages just 14.8" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. County Health Rankings reports 10,947 years of potential life lost per 100,000 (2025) — well above the national county median. 33.4% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Texas has no state income tax (Tax Foundation 2025). 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 $68,883, fair market rent of $1,110 for a two-bedroom, and a median home value of $113,500. Every figure on this page links to its underlying federal dataset with a retrieval date so you can audit the freshness yourself.

What these numbers say together
Rankin, TX (ZIP 79778) sits in Upton County. The page draws on 2 federal data feeds retrieved Apr 24. Top health signal: Health Insurance comes in above the national average at 18.7%. NCES lists 1 schools serving the area, 1 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $2,766. Average annual pay across local establishments runs $82,368 per worker (Census ZBP) — a high-wage local economy. BLS QCEW puts average annual pay at $87,660 per worker — about 34% above the US average and a clear high-wage signal. BLS LAUS reports county unemployment of just 1.7% (2024), well below the ~4.0% US average and consistent with a tight local labor market. 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. FEMA has issued 13 federal disaster declarations affecting this ZIP since 1993. Annual precipitation averages just 14.8" per NOAA's 1991–2020 Normals — an arid-climate ZCTA where landscaping and water-budget choices matter more than national averages suggest. County Health Rankings reports 10,947 years of potential life lost per 100,000 (2025) — well above the national county median. 33.4% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Texas has no state income tax (Tax Foundation 2025). 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 $68,883, fair market rent of $1,110 for a two-bedroom, and a median home value of $113,500. 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.
One concrete reading worth keeping: Depression prevalence sits near the national rate at 23.2%. 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.
