The Find Shortage Areas: Health Professional Shortage Area (HPSA) and Medically Underserved Area/Population (MUA/P) by Address tool helps you determine if a specific address is located in a designated shortage area. Shortage areas are designated by HRSA as specific geographic areas or sites that have the greatest need for health care. Shortage areas are categorized by specific needs (Primary Care HPSA, Mental Health HPSA, Dental Care HPSA, or MUA/P).
