The purpose of this report is to use data from a sample of recently booked arrestees in Maricopa County to examine the scope and nature of Maricopa County’s gang problem. In particular, this report supplements data presented in the bi-annual report on gangs conducted by the Arizona Criminal Justice Commission, which relies on official police data and their occasional white paper on gangs that relies on self-report data from school youth. We organized our analyses around six research questions: (1) what proportion of adult arrestees are involved in a gang, and what are the socio-demographic differences between those who are associated with a gang and those who are not; (2) what are the rituals associated with gang joining; (3) how do gang and non-gang arrestees differ in their experiences with crime, drug use and victimization; (4) what is the organizational structure and composition of gangs; (5) how do members socially identify with their gang; and (6) how and why do members leave their gang?

In step with other organizations, the Greater Phoenix Economic Council (the Valley’s regional public-private economic development organization) published a comprehensive 10-year economic development strategy that codified its change in direction to quality economic development in aerospace, bio-industry, advanced business and financial services, technology, and software. In early 2004, the Governor’s Council on Innovation and Technology issued Building Arizona’s Knowledge-Based Economy with scores of recommendations on venture capital, higher education, collaboration, workforce development, and other topics. Separately, each of these items would have been notable. Taken together, they demonstrate a strong commitment to the growth of a knowledge economy and to the multifaceted approaches needed to develop it.
