Mass Shooting Data

School shootings and threats of violence have reached alarming levels. While mental health professionals, first responders, schools, and communities possess various screening and assessment tools for mental illnesses, such as suicide, there remains a critical void in instruments specifically designed to identify and assess homicidal threats.

This lack of effective assessment tools leaves a dangerous gap. Homicide rates have soared from 12,992 in 2012 to a staggering 19,200 in 2022, with a significant portion (nearly 50%) perpetrated by individuals under the age of 30.

School shootings alone have impacted hundreds of thousands of children, leading to long-term mental health problems, reduced academic performance, and lower earning potential.

More than 100,000 American children attended a school at which a shooting took place in 2018 and 2019
Research indicates a higher rate of antidepressant use among those exposed to a school shooting in the years following the gun violence.
School shootings lead to drops in student enrollment and a decline in average test scores.
School shootings also lead to an increase in student absenteeism and the likelihood of needing to repeat a grade in the two following years.

Students exposed to shootings at their schools are less likely to graduate high school, go to college, and graduate college, and they are less likely to be employed and have lower earnings in their mid-20s.
Children and adolescents exposed to violence are at risk for poor long-term behavioral and mental health outcomes, such as depression, anxiety, and post-traumatic stress disorder, regardless of whether they are victims, direct witnesses, or hear about the crime.

At Homicide Zero, we envision a future where schools and communities have the tools they need to reduce the risk of homicide. Through early screening, assessment and intervention, we are aiming for ZERO incidents.
