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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Wyoming's uninsured rates vary considerably across zip codes, with several central and south-central areas displaying elevated rates above 25%, including a cluster of yellow-shaded zones near the center of the state likely corresponding to parts of Fremont County and the Wind River Reservation. The northeast and southeast corners of the state exhibit a patchwork of very low (dark purple, under 5%) and moderate uninsured rates, while many of the larger, sparsely populated zip codes in the western and northern regions appear in gray, suggesting insufficient data or very small populations. Urban corridors around Casper, Cheyenne, and Laramie generally show moderate uninsured rates in the 10–20% range, contrasting with the more extreme values found in rural and tribal areas.
