More than half of the people held in jails in Mississippi are held for federal or state agencies, primarily the state prison system. To avoid counting them twice, this population is not included in the yellow jails line. For annual counts of people in jails held for federal or state authorizes in Mississippi, see our table "Jail and prison incarcerated populations by state over time."
