Many residents of rural counties are affected negatively by shortages of health personnel and long travel distances to health care facilities. Just as importantly, their ability to access services can depend on having enough income to meet out-of-pocket health expenses. The U.S. Census Bureau released 2013-2017 five-year estimates from the American Community Survey (ACS) for every county in the nation, which show that in general, median household income is higher in urban counties than in rural areas. Likewise, poverty rates tend to be lower in urban areas than in rural areas.
