Alcatraz Facts and Figures: Inmates, Sentences and Daily Schedule

This page collects practical facts about the federal penitentiary on Alcatraz: how many men it held, how long they stayed, what they wore and how their day was organised.

Population

The usual population was about 250. The cellhouse had secure cells for 336, but it never filled up, so other federal inmates knew there would always be space for more troublemakers. Even with transfers coming and going, the population rarely went above 300, which is small for a prison and smaller than many county jails.

Over the 29 years of the penitentiary, records indicate 1,576 inmates spent time on the island. The figure is hard to pin down because a few men were there more than once, sometimes under different names or with different numbers.

No women

Alcatraz was built for incorrigible male federal prisoners. Other prisons held women, but none was set up on the Alcatraz model. There were no female inmates and no women working inside the cellhouse as officers or administrators. Some prisoners went twenty years or more without hearing a woman’s voice. A few, working on the dock or on maintenance crews, caught occasional sight of the wives and daughters of guards who lived on the island.

Length of stay

Inmates joked that you went to Alcatraz for at least five years, and this turned out roughly right, though not by rule: stays were open-ended. A man remained until he stopped being a troublemaker and was then sent back to his former prison. A few managed it in under five years, while as many as 200 needed more than ten. The typical period was six to eight years.

Some men returned later, because certain prisoners behaved better at Alcatraz than at “easier” prisons, partly because cells held one person. Most other prisons placed two or more in a cell, which creates problems.

Bureau of Prisons policy said no one should be paroled from Alcatraz. Those nearing the end of a sentence were generally sent back to their original prison for release. A handful were freed directly, usually because courts overturned a conviction or reorganised a sentence.

Original sentences

Some inmates carried multiple life terms, or strings of consecutive sentences adding up to hundreds of years. Others had begun with fairly short terms for minor offences and extended them with assaults or escape attempts after entering the system. A typical inmate had 20 to 25 years to serve.

Uniform

The clothing changed over time. Men wore trousers in the cellhouse and at work, wool at first and blue denim later, with overalls at work in the early years. They also had a cotton work shirt, a cotton jacket, a raincoat, a wool cap and usually a navy pea coat, plus a robe and slippers for bath day. Early inmates said they wore shoes without nails and belts with wooden fastenings to pass metal detectors.

Overalls and shirts were stencilled with the registry number that guards used for identification. It also showed how long a man had been there: those with four-digit numbers were seen as the new breed, while lower numbers earned respect as old timers.

A typical day

The timetable varied slightly but was usually as follows.

• 6:30 wake-up bell, stand for count, dress and clean the cell
• March to the mess hall for breakfast, back to the cell for a count
• Line up in the recreation yard for work details, with counts on the way and every half hour at work
• About 11:30 return to the cellhouse for count, then lunch and another count
• Back to work, finishing at 4:30, with a count on return
• Dinner, return to the cell, counts through the evening
• 9:30 lights out, with a count every hour through the night

Weekends followed the same pattern with chapel and yard time instead of work. Holidays meant a movie and yard time, and showers were fitted in twice a week.

More detail on specific topics is on the pages about famous inmates, the mess hall and maximum custody.

Putting the numbers in context

A population of about 250 meant everyone knew everyone. Officers learned the habits of each inmate, and inmates learned the officers. Combined with single-person cells and rigid timetables, this small scale made Alcatraz feel more like a tightly managed institution than a typical big-house prison, and it explains why so many of the island’s stories centre on a few names and a few incidents.
