Uniform Crime Reporting (UCR) Program Data: A Practitioner’s Guide

Association of Minimum Age Laws for Handgun Purchase and Possession With Homicides Perpetrated by Young Adults Aged 18 to 20 Years

“…Firearm violence disproportionately involves young adults, both as victims and as perpetrators. In 2017, 11% of those who died due to firearm homicide and 10% of known perpetrators were aged 18 to 20 years, although this age group made up only 4% of the US population . Youth and young adults are at higher risk of violent behavior toward themselves and others, owing in part to biological processes during adolescence and early adulthood; the brain areas that govern capabilities for risk-reward assessment and impulse control are still developing well into the early 20s …”

De‐prosecution and death: A synthetic control analysis of the impact of de‐prosecution on homicides

“…In addition to the Sentencing Commission data, homicide data for the largest 100 cities in the United States have been gathered from the FBI's Uniform Crime Report ("UCR"), specifically using the Supplementary Homicide Report ("SHR"). The SHR provides details about each homicide by police jurisdiction for every year, including victim and offender data, weapons used, and other details (Kaplan, 2021). Once again, the data for 2010-2019 are used.…”

Explainable machine learning for predicting homicide clearance in the United States

“…This involves discrepancies between SHR and different data sources virtually measuring the same phenomenon, such as information collected by the Center for Disease Control and Prevention (CDC) in the WONDER dataset and the Offenses Known and Clearances by Arrest data which are part of the UCR National Incident-Based Reporting System (NIBRS) program (Kaplan, 2020). Comparative discrepancies translate into underreporting for SHR data, which hinders research (and policy) reliability of findings obtained by using such a source.…”
