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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in and around Dearborn exhibit the highest uninsured rates in the Detroit metro, with several areas reaching 15–25%, likely reflecting large immigrant and refugee communities with lower access to employer-sponsored coverage. Most suburban zip codes to the north and west—including Farmington Hills, Livonia, Sterling Heights, and St. Clair Shores—cluster tightly in the 2–7% range, indicating broadly consistent insurance coverage across the outer suburbs. Detroit proper presents a mixed pattern, with some central zip codes showing moderately elevated uninsured rates while others fall in line with surrounding suburban levels, suggesting significant intra-city variation tied to neighborhood-level demographics and economic conditions.
