The purpose of this report is to examine methamphetamine use among adult arrestees and juvenile detainees in Maricopa County, Arizona. We relied on data from the Arizona Arrestee Reporting Information Network (AARIN) to address the following five questions:
1. What percent of adult arrestees are methamphetamine users and what are their social characteristics?
2. What is the relationship between methamphetamine use and arresting offense?
3. What is the relationship between methamphetamine use by parents and the presence of children in the household?
4. What percent of methamphetamine users are receiving treatment for their drug use?
5. What percent of juvenile detainees are methamphetamine users and what are their social and legal characteristics?

The general goal of this report was to collect data on citizens’ needs for information about neighborhood crime patterns and trends, terrorism, and public emergency planning and response in the western region of the Phoenix metropolitan area. There was particular interest in obtaining citizen feedback on data-sharing questions related to terrorism prevention.
