Fresh.Data current as of Apr 24, 2026
Upton, WY (ZIP 82730) sits in Weston County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Annual Checkup comes in above the national average at 70.4%. NCES lists 2 schools serving the area, 2 non-charter. IRS data shows average household income (AGI) of $72,351, 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. FEMA has issued 9 federal disaster declarations affecting this ZIP since 1978. Annual average temperature is just 44.8°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. 30.8% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Wyoming has no state income tax, saving the local median household (AGI $72,351) approximately $3,328/year vs the US average effective state tax rate. New residents arriving here predominantly come from Campbell County, WY (IRS SOI Migration, 2022-2023). 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 $65,703, fair market rent of $1,150 for a two-bedroom, and a typical home value of $258,996, down 0.8% 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.

Upton, WY (ZIP 82730) sits in Weston County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Annual Checkup comes in above the national average at 70.4%. NCES lists 2 schools serving the area, 2 non-charter. IRS data shows average household income (AGI) of $72,351, 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. FEMA has issued 9 federal disaster declarations affecting this ZIP since 1978. Annual average temperature is just 44.8°F per NOAA's 1991–2020 Climate Normals — a notably cold-weather climate. 30.8% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Wyoming has no state income tax, saving the local median household (AGI $72,351) approximately $3,328/year vs the US average effective state tax rate. New residents arriving here predominantly come from Campbell County, WY (IRS SOI Migration, 2022-2023). 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 $65,703, fair market rent of $1,150 for a two-bedroom, and a typical home value of $258,996, down 0.8% 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 20.2%. 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.

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.
