Gun violence and violent crime more generally impose substantial costs on communities, including in Washington, DC. The Cost of Gun Violence in Washington, DC, project examined research on the broader community-level costs of gun violence on (1) economic indicators, such as business activity and the housing market, and (2) educational outcomes, such as test scores and graduation rates. We also summarized the extent of gun violence, economic indicators, and educational outcomes in Washington, DC, using publicly available data. And, to the extent possible, we put the costs in dollar terms. 

This appendix outlines the methodologies for our “Economic Costs of Gun Violence in Washington, DC” fact sheet and “Educational Costs of Gun Violence: Implications for Washington, DC” brief.
