Jails matter. But who is listening?
Most of the people who go to prison or jail in a year go to jail, so why don't policymakers pay more attention to jails?

One out of every three people who are locked up tonight are sitting in a local jail, not a state or federal prison. There are 3,283 jails in America, yet jails receive scant attention. The legislative, judicial and executive decisions that have fueled the explosion of our state prison populations are becoming well-known; but the myriad of subtle policy decisions that have sent our jail populations upwards are off the public’s radar.
Jails need to be a policy focus, as the Vera Institute of Justice recently argued in its aptly-titled report Incarceration’s Front Door: The Misuse of Jails in America.
Jails matter because a staggering 11 million people cycle through them each year. As we explained last year:
Jail churn is particularly high because at any given moment most of the 722,000 people in local jails have not been convicted and are in jail because they are either too poor to make bail and are being held before trial, or because they’ve just been arrested and will make bail in the next few hours or days. The remainder of the people in jail — almost 300,000 — are serving time for minor offenses, generally misdemeanors with sentences under a year.
So when we talk about jails we have to keep our eye on two numbers: the number of people in jail on a given day and the sheer volume of people who cycle through them as shown in this analysis of Bureau of Justice Statistics data:
Addressing the problem of jails means grappling with the tremendous churn through jails. How can we lessen the numbers who enter jails and reduce the time that 11 million people spend there each year?
This “pre-trial” or “unconvicted” population is driving the growth in jail populations. In fact, 99% of the growth in jails over the last 15 years has been a result of increases in the pre-trial population:
Virtually all of the growth in the jail population has been in the number of legally innocent people who are detained in jails.
These people are legally considered innocent until proven otherwise in court. But if they don’t have the money to post bail, the principle that they are legally innocent is not enough to keep them from being locked up until trial. A recent New York Times feature found that poverty is a frequent cause of pre-trial detention: in New York City even when bail is set at $500 or less, 85% of defendants were unable to afford bail.
Besides the injustice of our jails resembling modern day debtor’s prisons, excessive bail can have other harmful effects. Family life is disrupted, jobs and housing can be lost, and the combined effects can literally be fatal. Pre-trial detention also coerces people to plead guilty to minor offenses, including people who are factually innocent like the man featured in the New York Times article. Studies have also shown that people who are detained pretrial are more likely to be convicted than those who are able to afford bail.
Fortunately, the movement for bail reform is growing in places like New York City and the state of Massachusetts. But at the same time as we work to fix bail, we really should admit that the problem starts even before a bail hearing.
As Peter Goldberg, executive director of the Brooklyn Community Bail Fund put it in the New York Times article:
And the truth is, even meaningful bail reform is just the beginning. The real work is asking why we’re arresting so many people on low-level offenses in the first place, and why so many of them come from poor black and brown communities. Bail is easy.
Or to be more precise: fixing bail should be easy. Why it’s taking so long is a good question and getting to the bottom of this country’s jail problem is going to depend on both reducing the number of people we send to jail each year and making it far easier for those who have been arrested to resume their lives while the judicial process proceeds.


Since the beginning of the statistics almost 40 years ago, the probation population has grown much more quickly than either the number of people on parole or the number of people in federal, state and local prisons and jails. While about 2.3 million U.S. residents were behind bars in 2012, almost 4 million residents were under probation.
The rate of probation in Rhode Island is more than twice as high as the rate of probation in most other New England states. (Massachusetts was not included in the graph above because the state changed its reporting methods multiple times during the previous decade. However, in the most current available data, Massachusetts reported a rate of 1,033 adults on probation per 100,000 residents, less than half Rhode Island’s rate of 2,268 per 100,000 residents.)
Throughout the 1980s, the Texas imprisonment rate closely matched the national imprisonment rate. But between 1993 and 1998, the Texas imprisonment rate almost doubled, causing Texas’ total custody population to quickly escalate.
Beginning in 1993, the number of releases from Texas prisons fell behind the number of admissions, allowing the state’s total custody population to rise sharply for the next five years. Once release counts rose again to match admission counts, Texas’ total custody population leveled off and remained stagnant. These patterns show that admissions to and releases from prisons serve as at least one driving force behind rapidly changing prison populations.
