Jail vs. Prison

A jail is used to temporarily detain those who are suspected or convicted of a crime. It is used for the short-term, usually to hold those awaiting trial or to hold those convicted of low-level offenses that have sentences of one year or less. A prison is a facility that holds convicts who have committed crimes the legal system deems especially serious (e.g., repeated drunk driving offenses, first degree murder) for more long-term sentences.

Holds People awaiting trial; people sentenced for a short duration, typically less than a year. Not normally used in UK. People convicted of crimes; sentenced for a longer term
Jurisdiction In the U.S.A : Run by the county sheriff's department. In Canada, run by provincial governments. In the U.S.A. :Run by the Prisons and Corrections office in the respective states. There are also federal prisons. In Canada run by the federal government (also called Penitentiaries).

edit Length of Detention

The most notable difference between jails and prisons is that prison inmates have been tried and convicted of crimes, while those in jail may be awaiting trial, where they may yet be found innocent. A prison is under the jurisdiction of either federal or state governments, while a jail holds people accused under federal, state, county, and/or city laws. A jail holds inmates from two days up to one year.

edit In the United States

Jails are usually run by sheriffs and/or local governments and are designed to hold individuals awaiting dispostion of their case, waiting for transport to a state prison system following conviction, or serving time after a misdemeanor.

State prisons are operated by the state where the person was convicted of a felony. Federal prisons are operated by the Federal Bureau of Prisons (BOP) and are designed to hold individuals convicted of federal crimes, such as tax evasion, bank robbery, or kidnapping, among others.

Jails operate work release programs, boot camps, and other specialized services. They try to address educational needs, substance abuse needs, and vocational needs while managing inmate behavior.

State prison systems operate halfway houses, work release centers, and community restitution centers — all considered medium or minimum custody. Inmates assigned to such facilities are usually reaching the end of their sentences.

I'm pretty sure older English spelling is Gaol, and was used in parts of the commonwealth like Australia for long than in England. In fact, the prison vs jail distinction might be US only, as Prison has French roots.

It would be nice to add the word "imprisoned" to the clarification, as I believe it can apply to a broader set of confinements than strictly "prison". Thanks for the article!

who cares about the rest of the world anyways. If jail and prison mean the same thing, why have two words for it.? Sometimes people say jail, actually alot of times on tv, but I dont remember hearing someone refer to a prison sentence as a jail sentence.
IF you think there is no difference, or think there shouldn't be, then you are either lasy, or stupid, or both.

Also, I've heard that prisons are preferable to jails - the conditions are better since people are staying there long term.

The given definition might hold (to be generally) true in the USoA. However prison and jail/gaol are absolutely interchangeable in Australian English.
