Likewise, these estimates may not capture gang membership in jurisdictions that may have underreported or that declined to report.Based on these estimates, geospatial maps were prepared to visually display the reporting jurisdictions.Additionally, this assessment is supplemented by information retrieved from open source documents and data collected through April 2011.
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.
The National Gang Intelligence Center (NGIC) prepared the 2011 National Gang Threat Assessment (NGTA) to examine emerging gang trends and threats posed by criminal gangs to communities throughout the United States.
The 2011 NGTA enhances and builds on the gang-related trends and criminal threats identified in the 2009 assessment.
Our Word of the Year choice serves as a symbol of each year’s most meaningful events and lookup trends.
It is an opportunity for us to reflect on the language and ideas that represented each year.
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.
Reporting used to quantify the number of street and outlaw motorcycle gangs and gang members was primarily derived from the 2010 NDIC NDTS data and some supplemental NGIC reporting from our law enforcement partners.
NDIC annually conducts the NDTS to collect data on the threat posed by various illicit drugs in the United States.
These numbers are not used by the FBI or NGIC to rank jurisdictions on gang activity.
