Gun Violence as a Health Disparity
“MapForsyth has supported several projects of the
Program in Community Engagement at the Wake
Forest medical school. Their use of GIS documented the
association of gun violence with other health and social
disparities in specific Winston-Salem neighborhoods. No
other approach could provide this stark portrayal with
such power. The ability of GIS to provide visual
illustration of health and social issues lays an important
foundation for planning and intervention.”
