Nearly 50,000 People Were Held in Solitary Confinement in the U.S. Last Year, Study Finds
More than 900 had been held in isolation for more than a decade.

Despite a number of state reforms over the past decade, nearly 50,000 people were held in solitary confinement in prison systems across the country last year, according to a report released Wednesday.
The report, "Time-In-Cell: A 2021 Snapshot of Restrictive Housing," co-authored by the Correctional Leaders Association and the Arthur Liman Center for Public Interest Law at Yale Law School, estimates that as of July 2021, between 41,000 and 48,000 people were held in isolation in U.S. prison cells.
The report is part of a decadelong study on the number of prisoners held in solitary confinement, the most comprehensive attempt yet made to measure the use of solitary confinement in the U.S., which the authors define as isolation in a cell for 22 or more hours a day for 15 days or more. (In 2011, the United Nations Special Rapporteur on torture concluded that solitary confinement beyond 15 days constituted cruel and inhumane punishment.)
"The Liman report is the gold standard in tracking solitary confinement in US prisons," says David Fathi, director of the American Civil Liberties Union's National Prison Project. "Unfortunately, this time around 15 states refused to participate, including some of the most notorious users of long-term solitary confinement."
The reports show a gradual downward trend in the use of solitary confinement. The authors say three states reported holding no one in isolation in July, and two other states reported fewer than 10 people in solitary.
Prior to COVID-19, the daily number sat around 60,000 people, according to 2018 estimates. However, during the pandemic, the number of inmates held in solitary confinement spiked to 300,000, according to a report released by Unlock the Box, a coalition of civil rights groups that oppose solitary confinement.
In 2016, there were at least 67,000 inmates in solitary confinement, according to the survey, and in 2014, there were 80,000 to 100,000. Those numbers are all self-reported by jails and prisons.
Part of the decline is due to state reforms, and part is due to the overall decline in prison populations. Wednesday's report notes that "between 2018 and 2020, when the last report was published, legislators in more than twenty-five states introduced bills to limit the use of restrictive housing, and some fifteen enacted legislation."
Advocacy groups put pressure on state prison systems to limit the use of solitary confinement, citing evidence that locking human beings in tiny boxes alone for years at a time has profound negative psychological effects, especially on those already suffering or at risk of mental illness.
Such observations are not new. After visiting Pennsylvania's Eastern State Penitentiary in 1842, Charles Dickens wrote that the "immense amount of torture and agony" inflicted by solitary confinement was largely hidden from public view, and he denounced the practice as "a secret punishment which slumbering humanity is not roused up to stay."
Wednesday's report says that prison systems reported a total of 1,138 seriously mentally ill people in restrictive housing.
Advocacy groups also drew attention to the plight of people who had been held in solitary confinement for years, sometimes decades. One of the most notable cases was Albert Woodfox, who spent 43 years in solitary confinement, possibly the longest stint in U.S. history, in Louisiana's notorious Angola Prison. Woodfox was freed in 2016 and died earlier this month
According to Wednesday's report, 6,040 individuals were in solitary confinement for a year or more, and 924 had been in restrictive housing for more than a decade.
"While the apparent decline in solitary confinement is welcome news, the fact remains that the number of people in solitary should be zero," Fathi says. "Decades of evidence shows the irreversible physical and psychological harm long-term solitary confinement causes. There is no defensible reason for prisons and other detention facilities to keep using long term solitary confinement, which is recognized as a form of torture."

But enough about the January 6 protestors....
Not mentioned.
Thanks for reading the article so I didn’t have to.
I am making 80 US dollars per hr. to complete some internet services from home. I have not ever thought like it would even achievable however my confidant mate got 13,000 us dollars only in four weeks easily doing this best assignment and also she convinced me to avail. Look extra details

Did Pravda remind Soviet citizens about dissidents?
But they were trespassing on public property, and protesting for election integrity. Where's the pro-liberty angle?
You should know by now that HEAVILY ARMED INSURRECTION is the lone exception to Reason.com's soft-on-crime stance.

This wouldn't happen if we'd fully implement the Koch / Soros / Reason soft-on-crime #FreeTheCriminals and #EmptyThePrisons agenda.

I'd like to know a whole lot more about who was held in solitary. I have zero doubt that there are a lot of really bad guys in prison who need to be isolated from genpop just as much as a lot of genpop need to be isolated from society: they are predators.
50,000 out of, what, 1.5M total prisoners? one out of 30? It sounds high, but not implausible.
Let's do some real research here.
Like Tasers and SWAT, something that was to be used for extreme circumstance has become normal. Tasers were an alternative to deadly force, now they're used for compliance. SWAT was created for dangerous situations, now it's used to serve bench warrants. Solitary was to be used in extreme cases against dangerous people, and now it's standard discipline.
The same people who say stocks and gallows are cruel and unusual punishment support SWAT teams terrorizing families, Tasers being used for pain compliance, and solitary confinement for basic bullshit.
Why? It's easy. Zero tolerance is easy. Torture is easy. Throwing away the key is easy.
“Your agonizer, please.”
Thanks for ranting instead of answering the question.
I agree with the sentiment above but am even more concerned about what appears to be a growing trend : how much solitary confinement is solely for political retribution, ala Jan 6th misdemeanor insurrectionist wannabes? Police State much?
And even small towns have SWAT teams and military hardware. And they stand by for an hour and a half when an actual dangerous situation occurs.
The number also likely means the number of prisoners held in solitary for any time at all. If this includes suspects spending a day in solitary to investigate an assault it doesn't seem like a big deal.
Later he mentions prisoners being held for years at a time without mentioning this is only a small part of the population.
Doesn't the "years at a time" group include all death row and protective custody inmates? Are these activists demanding the increase in violence and rape that goes with pushing these people into gen pop or they delusional about who exactly is in prison and what it would take to provide safety?
This article is lacking two main items: duration and cause.
If those 50,000 people were held in isolation for a single day after stabbing their cellmate, that's a very different thing from 50,000 people continuously in solitary for the whole year because they mouthed off to the warden. And those 900 people who were there for a decade? Were they serial killers who already killed someone on the inside? How many were in protective custody because someone tried to kill them?
These are critical points that are definitely in the report, but are so critical to this article's thesis that it's negligent to not include them here.
Some are luckier than others. If I didn't have so much responsibility....
isolation in a cell for 22 or more hours a day for 15 days or more
Sounds like peace and quiet, not torture.
I hope you end up there.
Is that so? When they finally caught fugitive Whitey Bulger, he was beaten to death (7 to 10 minutes - padlock on a rope) within 24 hours of arriving at in prison by people who were obviously not in solitary confinement.
The number of people in solitary is not relevant. The relevant analysis is what they did to get into solitary and for how long. People like to preen about their opposition to this, but in reality any choice creates more violence. Rather than deal with this they pretend the number proves something.
You can tell when someone isn't serious about the issue, and is instead engaging in political hackery, when they avoid examining the real issue in favor of something presented as alarming but in fact meaningless.
Exactly. There are scumbags in prison who would gladly beat up anybody for any reason, kill them, rape the, no difference. They need to be isolated from other prisoners, just as all prisoners are isolated from civilians.
What's the alternative? A separate prison within the prison? We could call it ... solitary!
I have no doubt guards play politics, keep their bad friends out of solitary, put their bad friends' enemies in solitary.
But how many?
A little research is needed, not just a bunch of quotes from people with agendas.
There is no defensible reason for prisons and other detention facilities to keep using long term solitary confinement, which is recognized as a form of torture.
What if a guy keeps stabbing motherfuckers and just won't stop stabbing motherfuckers?
Mostly peaceful prisoners.
Fact check: Mr Stabby only stabs another 1% of his waking hours.
Statement mostly true.
Mostly == 1%?
Are those 924 in restrictive housing more than a decade folks in the SuperMax prisons? I actually do have a lot of concern about those.
They're not in for more than a decade at a stretch. They've done enough time in solitary that it ADDS UP to more than a decade.
So being beaten and raped and shanked is *not* torture? Give me solitary any day, with a pencil, pad, and some books. I want nothing to do with the trash culture of prison.
*Points to head* Can't have gangs, prison rape, or contraband when everyone is in solitary.
I would rather be in solitary than constantly raped.
I honestly do not understand how that is not a bigger issue. But whenever it's brought up, it's just as a joke.
This.
I also don’t understand why it’s treated as a joke. Even if someone was in for say, armed robbery, no one would find it funny if they shoved bamboo splints under his fingernails. But ass rape is supposed to be hilarious. Can you imagine anyone laughing if women were routinely raped in prison? We supposedly live in a “patriarchy,” so this is particularly puzzling to me.
You don't get sentenced to solitary at your trial - you have to do something to get there. Of course, they could whip recalcitrant prisoners, but that would be inhumane. Solitary is the nice way to deal with them. Most of them probably should have been executed anyway, so I see no problem with making them live a highly restricted life.
No doubt Dickens was also racist and sexist and homophobic, so who cares what he thought?
