Approximately one-third (948) of Sacramento County’s homeless population is unsheltered. Particularly noteworthy differences between 2013 and 2015 counts include a 7.9 percent increase in chronically homeless individuals and a 20.6 percent increase in unsheltered single adults. There has been a surge in criminal activity among homeless persons in Sacramento County as a result of numerous factors. For instance, new legislation led to the release of lower lever offenders into the communities, many of whom are living on the streets. Increased homelessness is also the result of rapidly rising housing prices that make it difficult for persons with limited skills, social, emotional, behavioral or substance use issues to secure housing. Homeless-related crimes vary but include (and are not limited to): chronic public intoxication, panhandling, loitering, trespassing, shoplifting, dealing drugs, and more. The Sacramento SPI team is seeking to develop research-based, innovative, data-driven approaches to homeless-related crime challenges currently confronting the Sacramento Sheriff’s Department.
