Key findings

What the HRSA Data Warehouse does not surface for Maricopa County, AZ on its own pages , computed from the retained designation mirror as of 2026-08-15. Each line carries its own denominator so it can be quoted as it stands.

    HRSA providers_needed summed once per HPSA id (no double-count across status rows): 195 primary care, 20 mental health, 75 dental. This is the federal gap estimate, not a headcount of practising clinicians.
