New residents arriving here predominantly come from Adair County, MO (IRS SOI Migration, 2022-2023). 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.

What these numbers say together
Callao, MO (ZIP 63534) sits in Macon County. The page draws on 2 federal data feeds retrieved Apr 27. Top health signal: High Blood Pressure comes in above the national average at 40.4%. NCES lists 1 schools serving the area, 1 non-charter. 3 colleges and universities serve the area, with median in-state tuition of $9,838. IRS data shows average household income (AGI) of $53,450 per tax return. BLS QCEW reports average annual pay of $43,944 per worker, roughly 33% below the US average. FEMA has issued 25 federal disaster declarations affecting this ZIP since 1973 — a high-frequency exposure profile. 29.1% of residents in this county are flagged low-access by USDA's 2025 Food Environment Atlas — a notable supermarket-access gap. Missouri levies a graduated state income tax (top rate 4.70%); a household at the local median AGI of $53,450 would pay roughly $1,507/year before deductions. New residents arriving here predominantly come from Adair County, MO (IRS SOI Migration, 2022-2023). 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 $890 for a two-bedroom, and a typical home value of $190,650, up 4.9% 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.
One concrete reading worth keeping: Depression prevalence sits higher the national rate at 24.1%. 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.
