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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Uninsured rates in Texas exhibit stark geographic disparities, with the highest concentrations (30–50%) clustering along the southern border region and in parts of the Texas Panhandle, areas characterized by large immigrant populations and limited employer-sponsored coverage. Major metropolitan cores—particularly in the Dallas-Fort Worth, Houston, Austin, and San Antonio regions—display a patchwork pattern where affluent suburban zip codes with very low uninsured rates (under 5%) sit adjacent to urban core zip codes exceeding 25%. West Texas and rural areas in the central and eastern parts of the state generally fall in the 15–25% range, reflecting the persistent challenges of healthcare access in sparsely populated regions with fewer insurance marketplace options.
