% of Population without Health Insurance, by Zip Code (ZCTA5) — Missouri

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the northwestern and west-central portions of Missouri exhibit notably higher uninsured rates, with several areas reaching 25–50%, while the St. Louis metropolitan area in the east and Kansas City's suburban zip codes generally display lower rates in the 0–10% range. Scattered yellow hotspots appearing in central Missouri and along the western border suggest pockets of acute coverage gaps, likely corresponding to rural communities with limited employer-sponsored insurance options. The southern Ozarks region presents a mixed pattern, with adjacent zip codes varying sharply between near-zero and 15–20% uninsured rates, indicating significant local disparities in insurance access.
