*Area Deprivation Index is a measure of socioeconomic deprivation that includes factors for the domains of income, education, employment, and housing quality. Percentile rankings range from 1 to 100, with higher values indicating higher levels of deprivation.

† Includes the combined Medicare Fee-for-Service and Medicare Advantage populations.
