Arrest, Release, Repeat: How police and jails are used to respond to social problems
How many people go to county jails every year, and how many times do they go? These basic data points — essential to understanding whether counties are using police and jails properly — weren't available until now. In our report, we break down the number of people booked in jail every year, including how many return multiple times. We go on to analyze the demographic characteristics of people who go to jail, including rates of poverty, access to health care, and race. Lastly, we present policy recommendations for counties hoping to change how their jails are used.
