Shortage Areas HRSA develops shortage designation criteria to determine whether a geographic area, population group or facility is a Health Professional Shortage Area (HPSA) or a Medically Underserved Area/Population (MUA/P). HPSAs may be designated as having a shortage of primary medical care, dental or mental health providers. They may be urban or rural areas, population groups, or medical or other public facilities. MUAs may be a whole county or a group of contiguous counties, a group of counties or civil divisions, or a group of urban census tracts in which residents have a shortage of health services. MUPs may include groups of persons who face economic, cultural or linguistic barriers to health care. The HRSA Data Warehouse (HDW) allows users to interact with data in charts, tables/reports, maps, and tools.
