|Summary||The AHRF, formally the Area Resource Files (ARF), is a database of information regarding the U.S. health care system and factors that may impact health care and health status in the U.S. The data contains nearly 6,000 variables and is available at the national, state and county levels. It is maintained and annually released by the U.S. Health and Human Services (HHS) Health Resources and Services Administration (HRSA). It includes information in eight different general topical areas: Health Care Professions, Health Facilities, Population Characteristics, Economics, Health Professions Training, Hospital Utilization, Hospital Expenditures, and Environment. The AHRF data integrates data from over 50 sources from a number of agencies including the American Medical Association, American Hospital Association, U.S. Census Bureau, CMS, Bureau of Labor Statistics, National Center for Health Statistics, and Veteran’s Administration.|
