A recent study in New York City found that of the 800 people who spent the most time cycling through the jail system, over half were homeless. The top charges in these cases were petit larceny, drug possession, and trespassing. Constantly rearresting homeless people for these offenses does little to alter their future behavior or reduce their impact on communities. And it certainly doesn't help to end their homelessness.
The cost of this process is exorbitant. New York City spent $129 million over 5 years to jail those 800 people. That's over $30,000 per person per year. Supportive housing costs less. And that amount doesn't include the costs of emergency room visits, shelter stays, outreach efforts, etc. In 2013 the Utah Housing and Community Development Division reported that the cost of emergency room treatment and jail time averaged over $16,000 a year per homeless person, while providing a fully subsidized apartment was only $11,000. A study by the University of New Mexico documented that providing people with housing reduced jail costs by 64%. Researchers in Central Florida showed that providing chronically homeless people with permanent housing and support services would save local taxpayers $149 million in spending on jails and health care. An in-depth case study conducted by researchers at the University of Southern California found that the total cost per person of public services for two years living on the streets was $187,288, compared to $107,032 for two years in permanent housing with support services, a savings of $80,256, or almost 43%. Criminal justice costs went from an average of over $23,000 to zero.
