Uninsured rates in the San Antonio metro concentrate most heavily in the south and southwest quadrants, where several zip codes southwest of Von Ormy and south of downtown reach 25–35% or higher, appearing in bright yellow-green tones. The northern and northeastern periphery—stretching toward New Braunfels and Schertz—consistently registers among the lowest uninsured rates at roughly 5–10%, reflecting the higher-income suburban corridors of those areas. A sharp gradient is visible radiating outward from the downtown core, where near-downtown zip codes on the south and west sides show markedly elevated uninsured levels compared to their counterparts just a few miles to the north and northwest.
