Difference between Prison and Jail

Key difference: Jails and prisons are part of the criminal justice system that also includes courts, law enforcement, and crime labs.

Jail

Jails and prisons are facilities that are used to confine individuals who are believed to have committed crimes and broken laws. Jails and prisons are part of the criminal justice system that also includes courts, law enforcement, and crime labs.

The main difference between a prison and a jail is the reason for which they are utilized. Jails are mainly used to house an individual who is awaiting trial or is awaiting his/her sentencing. Once the individual is sentenced, he/she is termed as a convict. If the convict’s crime is a misdemeanor and/or his sentence to be served is minor, i.e. in most cases less than a year; then the convict is housed at a jail.

Prison

However, if the convict’s crime is serious and his sentence to be served is lengthy; in most cases more than a year, then the convict is housed at a prison. A prison is usually bigger than a jail and more facilities and guards, in order to house even the most hardened criminals.
