Gangs affect American society at all levels, causing heightened fear,
crime, and economic costs. Violent criminal groups affect public safety,
community image, and quality of life in too many of our communities.
The purpose of the 2005 National Gang Threat Assessment is to provide
a national and regional picture of the threat posed by gangs. It is
anticipated that this document will help federal, state, and local
policymakers and law enforcement agency administrators understand
the dimensions of the gang problem and assist them in formulating
policy and allocating resources.
The National Alliance of Gang Investigators Associations (NAGIA)
prepared this report with funding from the Bureau of Justice Assistance.
The NAGIA is a cooperative organization currently composed of representatives
from 16 regional gang investigators associations representing over
15,000 gang investigators across the country, as well as federal agencies
and other organizations involved in gang-related matters.
