Importance  Firearm injury research in the US has focused on fatal injuries. The incidence and epidemiologic factors associated with nonfatal firearm injuries are less understood.

Objective  To evaluate estimates of incidence and trends over time of fatal and nonfatal firearm injuries.

Design, Setting, and Participants  A cross-sectional, ecologic study was conducted using data throughout the US from 2009 to 2017. Data on fatal injuries from the Centers for Disease Control and Prevention were combined with national data on emergency department visits for nonfatal firearm injury from the Nationwide Emergency Department (ED) sample. Data analysis was conducted from August 2019 to September 2020.

Exposures  Firearm injuries identified with International Classification of Diseases external cause of injury codes and categorized by intent of injury, age group, and urban-rural location.

Main Outcomes and Measures  Incidence, case fatality rate, and trends over time of firearm injury according to intent, age group, and urban-rural location.
