What these numbers say together
St. Marys, IA (ZIP 50241) sits in Warren County within the Des Moines-West Des Moines metro area. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Health Insurance comes in below the national average at 5.5%. No NCES schools are mapped to this ZIP in the current dataset. 3 colleges and universities serve the area, with median in-state tuition of $20,988. Local establishments report average pay of $16,417 per worker (Census ZBP) — below the US average. BLS QCEW reports average annual pay of $51,236 per worker, roughly 22% below the US average.

FEMA has issued 17 federal disaster declarations affecting this ZIP since 1973.

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 21.2%. 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.
