Available gang-related crime statistics for Los Angeles County have been spotty at best for many years. The most recent available statistics for any Los Angeles County jurisdiction are 2025 gang-related homicides for the City of Los Angeles (100 of 230 total homicides that year). Until this report, no other similar statistics for any portion of L.A. County had been reported since 2009, except for a single-year 2012 report for jurisdictions under the Sheriff. In 2016, the LAPD reported to the media that gang-related crime in Los Angeles had increased 14.6 percent in 2015 over 2014 and nearly 60% of homicides were gang-related. The Almanac was unsuccessful at finding specific data behind those specific numbers.

These include 491 homicides, nearly 7,047 felony assaults, approximately 5,518 robberies and just under 98 rapes." These numbers are not delineated by year.
