County Level: There are 3,142 counties in the United States. 
1 Each county has an elected Sheriff and 
deputies (a.k.a. police officers) work directly under the Sheriff. Deputies are no different from any other 
city police officer other than the Sheriff can be responsible for the courts and jails (a.k.a. correctional 
facility) in their respective county. But there are also many city police departments that are responsible for 
jails, so it just depends on the department. 
Each state is divided into counties, and each county, depending on size, could have a sheriff’s office.
