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

NOTE: Gray indicates insufficient data or a suppressed estimate.

Uninsured rates in the Phoenix metro area exhibit a clear central-city versus suburban divide, with zip codes in south and west Phoenix—particularly south of the I-10 corridor—displaying the highest concentrations at 20–30% or more, while outlying communities such as Gilbert, Chandler, and the northern Scottsdale area consistently fall below 10%. A notable cluster of elevated uninsured rates (15–25%) extends through central Phoenix and into Glendale, contrasting sharply with adjacent pockets near Scottsdale and Tempe where rates drop to the single digits. The gray-shaded zip codes on the metro periphery, likely reflecting sparse population or missing data, frame a core pattern where socioeconomic vulnerability tracks closely with historically lower-income neighborhoods west and south of downtown.
