Been addressed on other threads. Appalachia, one of the USAs poorest areas, is home to 25 million predominately white and impoverished people with high gun ownership and very low violent crime.
Appalachia consists almost entirely of extremely-sparsely-populated counties, and the crime rate is commensurate with the population density. Wherever the population is denser, the crime rate goes up. Knoxville and Chattanooga, Tennessee, two cities squarely within Appalachia, despite not being major cities have been among the top 30 highest-violent-crime-rate cities in America.
Mass shootings have also taken place within Appalachia, including some particularly deadly or otherwise notable ones, such as the 2008 U-U Church shooting, the Tree of Life synagogue shooting, and the Amish schoolhouse massacre.
