ZIP code case data comes from the Arizona Department of Health Services, reported by 5-digit ZIP code areas used by the United States Postal Service. Because the United States Census Bureau does not count population by postal code, The Republic used population data from Esri Demographics. The boundaries also come from Esri, and were provided by TomTom.
Blank areas represent ZIP code data suppressed by the health department or the absence of population totals.
Data as of May 21
