It supports US Department of Justice strategic objectives 2.2 (to reduce the threat, incidence, and prevalence of violent crime) and 2.4 (to reduce the threat, trafficking, use, and related violence of illegal drugs).
The assessment is based on federal, state, local, and tribal law enforcement and corrections agency intelligence, including information and data provided by the National Drug Intelligence Center (NDIC) and the National Gang Center.
The NGIC and its law enforcement partners documented increases in gang proliferation and migration nationwide and emerging threats. Reporting and intelligence collected over the past two years have demonstrated increases in the number of gangs and gang members as law enforcement authorities nationwide continue to identify gang members and share information regarding these groups.
Better reporting and collection has contributed greatly to the increased documentation and reporting of gang members and gang trends.
However, NGIC acknowledges that there may be some duplication or underreporting of gang members because of variations in each jurisdiction’s process to estimate gang activity.
In calculating the number of street and outlaw motorcycle gang members, respondents in each region were asked to select from a series of ranges of numbers.
Based on these estimates, geospatial maps were prepared to visually display the reporting jurisdictions.An overview of how these numbers were collected is described within the Scope and Methodology Section of the NGTA.The estimates were provided on a voluntary basis and may include estimates of gang members as well as gang associates.Law enforcement agencies nationwide continuously report new and emerging gang trends to the NGIC, as the NGIC continues to operate as a repository and dissemination hub for gang intelligence.This information provided by our law enforcement partners was used to identify many of the trends and issues included in this report.
