What these numbers say together
Colp, IL (ZIP 62921) sits in Williamson County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 46.6%.

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 21.7%. 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.
