Data, Statistics, and Reporting

Illustration describing the flow of data

The Injury Center uses data to understand when and why violence and injuries occur and how to prevent them. Data and data systems help us understand the burden of unintentional and violence-related injury and death in the United States.

Data Systems and Sources
Web-Based Injury Statistics Query and Reporting System (WISQARS)

CDC’s WISQARS™ is an interactive, online database that provides fatal and nonfatal injury, violent death, and cost of injury data. Researchers, the media, public health professionals, and the public can use WISQARS™ data to learn more about the public health and economic burden associated with unintentional and violence-related injury in the United States.

CDC’s SUDORS Dashboard is an interactive data visualization tool that displays comprehensive data on unintentional and undetermined intent drug overdose deaths that occurred in 2020, 2021, and 2022. Participating jurisdictions provided data from death certificates, coroner/medical examiner reports (including scene evidence, witness reports, and autopsy reports), and postmortem toxicology reports. Combined, these sources offer valuable data about drugs involved in overdose deaths, demographic characteristics, circumstances surrounding overdose deaths, and potential opportunities for intervention.

Explore fatal overdose trends.

Drug Overdose Surveillance and Epidemiology (DOSE) Dashboard

CDC’s DOSE Dashboard is an interactive data visualization tool that displays current nonfatal drug overdose-related emergency department (ED) data from syndromic surveillance systems. DOSE data can be used to compare monthly and annual trends in nonfatal drug overdose-related ED visits by drug types (i.e., all drugs, all opioids, heroin, and all stimulants), state, and sex and age group.

Explore fatal overdose trends.
