When people talk about being incarcerated, the words “jail” and “prison” are often used interchangeably, as if they mean exactly the same thing. In reality, there are differences between the two. Understanding these differences and when a person can be sentenced to one or the other is important for defendants and their families.
Understanding exactly who may spend time in jail helps families and defendants know what to expect:
Individuals who have been arrested and are awaiting their first court appearance typically remain in a local jail for processing and booking. Whether for a minor or serious alleged offense, everyone normally starts in a local facility initially.
If a person cannot post bail or is denied bail, they are held in jail until their trial or sentencing hearing, even if they haven’t been convicted yet. This can sometimes result in long stays for people whose cases take a while to resolve.
Some individuals are convicted and required to serve brief jail time, typically for offenses such as misdemeanors and probation violations that result in sentences of less than one year. Counties manage jail populations for these shorter sentences.
Jail is designed for much shorter stays, so the atmosphere is far more basic.
People in jail receive basic daily necessities: food, water, minimal clothing, and a place to sleep. Conditions are usually much less comfortable than in prison and can feel more crowded and chaotic due to inmate turnover.
Compared to prisons, jails usually offer little to no organized education, recreation, or personal job assignments. Jails generally allow short phone calls or visitation hours, but programming is minimal.
Since detention is often temporary, any social or recreational time is usually strictly controlled and may consist of only occasional access to a group area, courtyard, or shared dayroom.
Not all jails are the same, but generally, this is how jails in Arizona work.
Once someone has been convicted, most often of a felony, and sentenced to more than one year, they’re transferred from jail to a state or federal prison to serve out their sentence.
Prisons are built with the expectation that inmates will be there for a year or more, so they’re developed with more structure and routines.
Inmates are assigned to specific housing units or cellblocks, with designated beds and daily routines. These units help manage the larger and more permanent population of a prison compared to a jail.
Nearly every inmate in a state prison will be assigned to a work detail or institutional job, ranging from kitchen service and laundry to groundskeeping and manufacturing tasks. These jobs are mandatory and can structure much of an inmate’s schedule.
Prisons offer structured opportunities, including classes (such as GED, vocational, and college distance learning), religious worship, and exercise yard time. Access to these programs is sometimes determined by security level, behavior, or the length of the sentence.
Prisoners can earn modest wages from allowable jobs and use commissary accounts to buy extra food, soap, paper, envelopes, or treats. The commissary serves as a small shop for approved personal comfort items, which can be purchased using earnings or deposited funds.
Understanding these differences can help families prepare for what to expect, whether awaiting trial or adjusting to a long-term sentence in Arizona.
