About 3 million people are injured in motor vehicle crashes every year in the United States. Linking existing data sources such as police, hospital, and emergency medical service (EMS) records is one way to better understand these crashes. Data linkage is essential to inform injury prevention programs, policies, and decision making. The fact sheet explains how states can start or expand a data linkage program. Decision makers and public health professionals can use the new data linkage fact sheet to learn how linking data can help states and communities better target crash prevention efforts.
