The Sustainable Development Goals (SDGs) are 17 goals set by the United Nations to be implemented by all member states by 2030. Adopted in 2015, they outline a vision of development in which peace and security are an integral part. SDG 16,which seeks to “promote peaceful and inclusive societies for sustainable development,” includes targets and indicators focused on reducing violence (Target 16.1) and the proliferation of illicit arms (Target 16.4). The indicators – or measurement criteria – of these targets include the number of victims of intentional homicide (Indicator 16.1.1), the number of conflict-related deaths (Indicator 16.1.2), and the number of illicit firearms collected and traced (Indicator 16.4.2). In light of these targets and indicators, GunPolicy.org provides granular national data pertaining to homicides, gun homicides, conflict deaths, disarmament efforts, and marking and tracing.
