Mass Shootings Becoming More Prevalent, CRS Finds

08.03.15 | 2 min read | Text by Steven Aftergood

Mass murder involving firearms has become more prevalent in the United States over recent decades, according to data presented in a new report from the Congressional Research Service.

In the 1970s, there was an average of 1.1 such mass homicide incidents per year, with 5.5 victims murdered and 2.0 wounded per incident. The numbers have increased each decade since then. By 2010-2013, there was an average of 4.5 incidents per year, with 7.4 victims murdered and 6.3 wounded per incident.

The CRS report said that the prospects for a legislative response to such mass murders might possibly be enhanced if the quality and specificity of reporting on them were improved.

“With improved data, policymakers would arguably have additional vantage points from which to assess the legislative proposals that are inevitably made in the wake of these tragedies.”

CRS therefore suggested requiring federal agencies to report annually on firearms-related mass murders, including data on (1) offender acquisition of firearms, (2) types of firearms used, (3) amounts and types of ammunition carried and shots fired, (4) killed and wounded counts, (5) offender histories of mental illness and domestic violence, and (6) victim-offender relationships.

A copy of the new CRS report was obtained by Secrecy News. See Mass Murder with Firearms, 1999-2013, July 30, 2015.
