The weekly turnover rate of inmates is approximately 55%, meaning that every week more than half of these inmates are released and then replaced with new offenders being booked into jail.
The charts below break down the men, women, races, ethnicities and the types of crimes that people are arrested and incarcerated for in both Dane County and state prisons throughout the country.
