What these numbers say together
Leadwood, MO (ZIP 63653) sits in St. Francois County. The page draws on 1 federal data feed retrieved Apr 24. Top health signal: Obesity comes in above the national average at 42.0%. No NCES schools are mapped to this ZIP in the current dataset. 1 college or university serves the area, with median in-state tuition of $5,660. 35% of returns claim the Earned Income Tax Credit (IRS), a higher share than most ZIPs. Local establishments report average pay of $16,308 per worker (Census ZBP) — below the US average. BLS QCEW reports average annual pay of $43,743 per worker, roughly 33% below the US average. FEMA has issued 20 federal disaster declarations affecting this ZIP since 1976 — a high-frequency exposure profile. County Health Rankings reports 12,667 years of potential life lost per 100,000 (2025) — well above the national county median. Missouri levies a graduated state income tax (top rate 4.70%); a household at the local median AGI of $38,868 would pay roughly $1,096/year before deductions. IRS migration data (2022-2023) shows a net gain of 467 residents (248 households) — the ZIP's primary county is growing. 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 $37,426, fair market rent of $960 for a two-bedroom, and a typical home value of $85,797, down 4.1% 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.
- Fair market rent for a two-bedroom ($960/month, HUD SAFMR) represents 31% of median household income ($37,426, Census ACS) — above the 30% affordability threshold commonly used by housing experts.
- Lower median household income ($37,426, Census ACS) sits alongside an above-average 42.0% obesity rate (CDC PLACES) — a pattern that correlates with reduced healthcare access in lower-income areas.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 29.0%. 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.
