People with mental illness are significantly overrepresented in the criminal justice system
The rate of mental illness in state prisons and jails in the United States (16%) is at least three times the rate in the general population (5%). The rates of mental illness in Oregon state prisons and county jails are at least this high. i


At least three-quarters of people with mental illness who are incarcerated have a co-occurring substance abuse disorder. ii


Men who have been involved in the New York State public mental health system are four times more likely to be incarcerated than men in the general population. For women, the ratio is six to one. iii



Many of them have committed minor crimes
Nearly half the inmates with a mental illness in state or federal prison in the United States are incarcerated for committing a nonviolent crime.iv



They stay longer in prison and jail
On Riker's Island, New York City’s largest jail, the average length of stay for all offenders is 42 days; it is 215 days for inmates with a serious mental illness. v


In Pennsylvania state prisons, during the year 2000, inmates with serious mental illness were three times as likely to serve their maximum sentence as other inmates. vi



They are extremely expensive to incarcerate
The Monroe County, New York Jail spends approximately $315,000 per year on overtime for deputies who are conducting twenty-four hour suicide watch. vii


The Pennsylvania Department of Corrections estimates that it costs approximately $80 per day to incarcerate an average inmate and $140 per day to incarcerate a person with serious mental illness. viii



And, without a coordinated response, many will be treated through expensive public safety and crisis services
During the year 2000, taxpayers of King County, Washington spent over $1.1 million on drug and alcohol acute services and criminal justice resources for just 20 individuals. ix


In Summit County, Ohio, during the year 2001, the cost to taxpayers for a similar group of 20 individuals was $1.3 million. x



Programs that provide intensive community-based services to individuals with mental illness who have been involved with the criminal justice system have proven extremely cost-effective.

Preliminary findings from a federally sponsored multi-site diversion project indicate that diverting people with mental illness from the criminal justice system generates statistically significant savings equal to the cost of the added services that individuals receive in the community.
