What these numbers say together
Sheridan Lake, CO (ZIP 81071) sits in Kiowa County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: Obesity comes in below the national average at 26.8%. NCES lists 2 schools serving the area, 2 non-charter. 5 colleges and universities serve the area, with median in-state tuition of $4,608. IRS data shows average household income (AGI) of $135,060, well above the ~$45K national average per return. BLS QCEW reports average annual pay of $44,375 per worker, roughly 32% below the US average. FEMA has issued 11 federal disaster declarations affecting this ZIP since 1965. Per USDA's Food Environment Atlas, 100.0% of residents in this county live more than 1 mile (urban) or 10 miles (rural) from the nearest supermarket — a deep food-access gap. 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 $45,250, fair market rent of $1,560 for a two-bedroom, and a 27.0% poverty rate (well above the ~12% US average). 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 24.3%. 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.
