The rows are used as the “base” population for calculating agreement, for example, 86.6% of the rural population identified by the HRSA definition was also identified in the CDC definition, while 65.2% of the rural population identified by the CDC definition was also identified in the HRSA definition.
CBSA indicates Core-Based Statistical Area; CDC, Centers for Disease Control and Prevention; FAR, Frontier and Remote; HRSA, Health Resources and Services Administration; RCC, Rural Continuum Code; RUCA, Rural-Urban Commuting Area; UA/UC, Urban Area/Urban Cluster; UIC, Urban Influence Code.
