medically underserved areas and populations (MUA and MUP)

Designations that identify areas and populations that have too few primary care providers, high infant mortality, high poverty and/or high elderly population. MUAs and MUPs involve the application of the Index of Medical Underservice to a service area or population group. MUAs may include groups of census tracts that have a population-to-provider ratio indicating a shortage. MUPs may include groups of persons who face economic, cultural or linguistic barriers to health care.
