What these numbers say together
Henderson, IL (ZIP 61439) sits in Knox County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Health Insurance comes in below the national average at 7.0%. No NCES schools are mapped to this ZIP in the current dataset. 4 colleges and universities serve the area, with median in-state tuition of $30,093. BLS QCEW reports average annual pay of $46,491 per worker, roughly 29% below the US average. Social vulnerability is low in this ZIP at the 18th percentile (CDC SVI), reflecting strong baseline resilience to public-health emergencies and natural disasters. FEMA has issued 11 federal disaster declarations affecting this ZIP since 1974. 26.9% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. IRS migration data (2022-2023) shows a net loss of 232 residents (186 households) — the ZIP's primary county is shrinking. 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 $55,500, fair market rent of $1,050 for a two-bedroom, and a 30.4% 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 near the national rate at 20.7%. 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.
