CDC WONDER is one of the most powerful free tools available for reporters covering gun violence, drug overdoses, suicide or other causes of death. It draws on decades of death certificate data and lets you build custom queries that filter by cause of death, age, sex, race, geography and year. You can quickly pull county-level firearm mortality rates, compare suicide trends across states or track how drug overdose deaths have shifted over time. Because it uses ICD (International Classification of Diseases) codes, you can isolate specific causes of death, including accidental shootings versus homicides versus self-inflicted gunshot wounds.
