ZipCrawl

NOTE: Gray indicates insufficient data or a suppressed estimate.

Zip codes in the northern inland and far eastern portions of the San Diego metro, particularly in the unincorporated areas beyond Poway and northeast of Santee, exhibit the lowest uninsured rates at under 5%, while a distinct cluster of elevated uninsured rates (15–25%+) emerges along the central coastal corridor near Encinitas and in pockets west of the I-15 corridor. The southern urban core around National City, Chula Vista, and central San Diego displays moderate-to-high uninsured percentages, with one zip code near the San Diego label standing out with notably higher coverage gaps approaching 20% or more. A small area just southeast of La Mesa shows an anomalously high uninsured rate (appearing teal/green on the scale, suggesting roughly 15–20%), contrasting sharply with adjacent zip codes that fall below 10%.
