Flagging for Mental Health Needs in New York City Jails: Prevalence and Timing

While it is well-established that a substantial portion of people in NYC jails are designated for mental health services, less is known about when during their incarceration these needs are first identified. This brief examines the prevalence and timing of the “Brad H” flag, assigned to anyone who is diagnosed, screened for, requesting, or receiving mental health services while incarcerated in New York City jails, covering the period from June 2, 2016 to March 24, 2025.

Specifically, we looked at increases in the fraction of the NYC jail population that flag for mental health needs, how long it takes for incarcerated people to receive a Brad H flag, what share of their jail stay people spend designated for mental health services, disparities in flagging by gender, race, and custody level, and how flagging relates to overall length of stay.

These findings draw from the Data Collaborative for Justice’s New York City Jail Population Tracker.
