Objectives

Gun violence in the USA is a pressing social and public health issue. As rates of gun violence continue to rise, deaths resulting from such violence rise as well. School shootings, in particular, are at their highest recorded levels. In this study, we examined rates of intentional firearm deaths, mass shootings, and school mass shootings in the USA using data from the past 5 years, 2017–2022, to assess trends and reappraise prior examination of this issue.

Methods

Extant data regarding shooting deaths from 2017 through 2020 were obtained from the Centers for Disease Control and Prevention, National Center for Injury Prevention and Control, the web-based injury statistics query and reporting system (WISQARS), and, for school shootings in particular (2017–2022), from Everytown Research & Policy.

Results

The number of intentional firearm deaths and the crude death rates increased from 2017 to 2020 in all age categories; crude death rates rose from 4.47 in 2017 to 5.88 in 2020. School shootings made a sharp decline in 2020—understandably so, given the onset of the COVID-19 pandemic and subsequent government or locally mandated school shutdowns—but rose again sharply in 2021.

Conclusions

Recent data suggest continued upward trends in school shootings, school mass shootings, and related deaths over the past 5 years. Notably, gun violence disproportionately affects boys, especially Black boys, with much higher gun deaths per capita for this group than for any other group of youth. Implications for policy and practice are provided.

Trends in mass shootings in the United States (2013–2021): A worsening American epidemic of death

https://doi.org/10.1016/j.amjsurg.2023.03.028

Background

Mass shootings represent a significant problem in the United States (US). This study aimed to examine trends in mass shootings in the US over time.

Methods

Retrospective mass shooting data (1/2013–12/2021) were collected from the Gun Violence Archive. A scatterplot was constructed showing predicted (extrapolated from 2013 to 2019) versus actual total mass shootings in 2020 and 2021. Multivariate linear regressions were performed to evaluate trends in mass shootings over time, associated with gun law strength.

Results

Mass shooting incidents, injuries, and deaths in 2020 and 2021 exceeded extrapolations from previous years. When comparing 2019 to 2020, stronger gun laws were associated with decreased monthly mass shooting deaths. For these same strong gun law states, monthly mass shooting deaths decreased when comparing 2019 to 2021 and comparing 2020 to 2021.

Conclusions

US mass shootings have increased over the past decade. Stronger gun laws appear associated with fewer monthly mass shooting-related deaths. Firearm-related legislation may at least partially, curtail the worsening of this substantial “American problem” of mass shootings.
