The data can help researchers better understand the harms of mass incarceration.

by Peter Wagner and Emily Widra, June 30, 2022

Now that we’ve started publishing a series of reports about where incarcerated people call home in each of the states that have ended prison gerrymandering, that raises the common question: Can you also do this for other populations under criminal justice system control, such as people on probation or parole? This comes up in a number of contexts, but to pick one example, someone might be running a campaign to change a state law that denies people on parole the right to vote, and they might want to make the numerical impact a little more clear for specific legislators who might support or oppose the legislation.

The short answer is: Because this data is about people in prison — not people on probation or parole — it can’t precisely answer this question, but it can illuminate the patterns and scale of correctional control in an area.

A simple strategy to apply our data to other populations — and one that might be enough for your purposes or a proof of concept for more in-depth research1 later — would be to make the relatively safe assumption that parolees (for example) are spatially distributed across the state in a way that is roughly similar to the distribution of incarcerated people. (If you have reasons to believe that the distribution is different, then this of course won’t work.)

In order to estimate the number of parolees in a particular geography, all you would need to know is the state-level ratio of parolees (or another relevant population) to incarcerated people and then apply that ratio to each geography in our report. For example, in New York State there were 44,917 people2 on parole in 2020 and our report says that 39,027 people were reallocated3 to their home addresses from state prisons that year, for a ratio of 115%. You simply need to multiply the number of incarcerated people in each legislative district, neighborhood, etc. by that ratio to get a fair estimate of the number of parolees in that area. A similar approach could be used for people on probation or any other population that you have good reason to believe is distributed similarly to people in prison.

If you find this general methodology helpful, here are two other suggestions and warnings as you proceed:

  • Multiplying whole numbers of people by a percentage will almost surely result in fractional people. You’ll need to decide whether to round the numbers to keep this simpler or to keep the fraction as a way to emphasize that it’s an estimate. Both choices are fine and just depend on your intended use.
  • As your geographies get smaller, the accuracy of a state-level ratio between parolees and the incarcerated people will become less accurate. How small is too small is a value judgement you’ll need to make based on your knowledge of your state and your own goals, but if you wanted a starting point, in our series of reports we generally didn’t rely on or highlight incarceration rate data where the total number of incarcerated people in that geography was less than 10.

  1. The far more precise, although far more complicated way to answer this question would be to develop a relationship with a parole or probation agency, determine if they collect home address data, convince them to share that list of home addresses with other researchers under appropriate privacy protections, and then have the researchers map all of those addresses and then aggregate them up to the various geographies of interest to you.  ↩

  3. This number is not, as our report methodology explains, the total population of the New York State prison system. For this conversion to work you want to compare the total parole population to the number of people reallocated.  ↩


New data visualizations expose the harms of mass incarceration

by Mike Wessler, May 19, 2022

This briefing has been updated with new versions of these charts in 2024.

Here at the Prison Policy Initiative, we know a strong visual can drive home a point, change someone’s mind, or spur a person to action. It is why data visualizations are a core part of our research and communications strategy.

We usually only update our data visualizations about mass incarceration when a new report or briefing requires it. However, some graphs are so powerful that they warrant special treatment. In recent months, new data has been released about jail suicides, racial disparities, probation, and state incarceration rates. So we’ve updated a few of our most impactful charts with this new data to equip advocates, lawmakers, and journalists with the most up-to-date information available.

 

Racial disparities in the criminal legal system

From arrest to sentencing, racial and ethnic disparities are a defining characteristic of our country’s criminal legal system. The system of mass incarceration particularly targets Black people, who are 13 percent of the U.S. population but are 38 percent of the people in jails and prisons.

These updated charts show how people of color, particularly Black and Native American people, are disproportionately incarcerated in the United States.

  • Chart showing Black people are incarcerated in prison at higher rates than any other race, 1,096 per 100,000.
  • Chart showing Black people are incarcerated in jail at higher rates than any other race, 600 per 100,000.
  • Chart showing Black men are incarcerated in prison at higher rates than any other race, 2,203 per 100,000.
  • Chart showing women's prison incarceration rates by race.

The original version of the charts showing racial disparities in incarceration rates was published in The U.S. criminal justice system disproportionately hurts Native people: the data visualized. The original version of the charts showing racial disparities in prison incarceration rates by sex was published in Visualizing the racial disparities in mass incarceration.

Visit our Racial Justice page for more reports, briefings, research, and visualizations focused on the intersection of race and mass incarceration.

 

State policies drive mass incarceration

While the activities of Congress often grab headlines, it’s state legislatures that have a chance to make the most progress toward ending mass incarceration.

That’s because, as these charts make clear, state governments and their policies are responsible for the vast majority of people incarcerated in this country. And while the COVID pandemic has led to recent drops in incarceration rates, without intentional action from the states, these reductions will almost certainly be short-lived.

  • Chart showing most people are incarcerated in state prisons — more than 1 million people.
  • Chart showing most people are incarcerated in state prisons by rate.
  • Chart showing women's incarceration rates by facility type.
  • Chart showing the number of people in state prison with long sentences has tripled since 1999.

The original version of the charts showing how state policy drives mass incarceration was published in Tracking State Prison Growth in 50 States. The original version of the charts showing how state policy drives women’s incarceration growth was published in The Gender Divide: Tracking Women’s State Prison Growth. The chart “Long sentences” was originally published in Eight Keys to Mercy: How to shorten excessive prison sentences.

 

Suicide is the leading cause of death in jails

Suicide is the single leading cause of death for people in jail, a fact that isn’t surprising considering the mountains of research that shows incarceration is inherently bad for a person’s mental health. As this updated chart shows, someone in jail is more than three times as likely to die from suicide as someone in the general U.S. population.

Chart showing suicide rates in prisons and jails have dramatically increased over the last 20 years. The original version of this chart was published in The life-threatening reality of short jail stays

 

The long arms of mass incarceration

For many people, their prison sentence tells only part of the story of their involvement with the criminal legal system. As a result of prohibitively high cash bail, they are often held in a local jail for weeks, months, or even years before they are convicted of a crime. And then, once they’re released from prison, they often remain under state supervision through parole for years, living with the constant threat of being jailed for a technical violation.

As these updated charts show, pretrial detention is the driver of jail population growth over the last 20 years, and roughly half of all people under correctional control are on probation. And despite recent pandemic-related reductions in these numbers, they’re still too high and likely to increase as pandemic slowdowns ease.

  • Chart showing nearly twice as many people are on probation than in prison and jails.
  • Chart showing the growth in jail populations is due to increases in pretrial detention.

The chart “Probation Leading form of Correctional Control” was originally published in Probation: The nicest sounding way to grease the skids of mass incarceration. The chart “Pretrial policies drive jail growth” was originally published in Era of Mass Expansion: Why State Officials Should Fight Jail Growth.

Visit our Probation and Parole page for more reports, briefings, and visualizations that show that someone isn’t free just because they’re not behind bars. And check out our Jails and Bail page for more research on these institutions’ roles in the carceral system.

We’ve also updated the underlying data behind some of these charts in our data toolbox to empower advocates, lawmakers, and journalists to show the consequences of mass incarceration in their communities. If you’re using this data in your work, we want to know about it.


We worked with the National Consumer Law Center to explain how, at every state of incarceration, governments and private corporations are draining money from those who can least afford it.

In a new piece in Inquest, our general counsel Stephen Raher and Ariel Nelson of the National Consumer Law Center expose the cycle of exploitation that saps money from incarcerated people and their loved ones. The piece provides a big-picture overview of how government agencies and private corporations are profiting off of this system. It explains there are three stages in the cycle:

  1. First, companies and governments take a cut of money coming into prisons. Even in prison, a person needs money to survive, and because prison wages are so low, many incarcerated people rely on money transfers from loved ones to survive. At a time when people in the free world can instantly send money through their smartphones for free, prison money transfers still come with a whopping 20% average fee.
  2. Next, while in prison, incarcerated people are subjected to outlandish rates and prices for essentials — like communications services, food, and hygiene products — and burdened with mandatory fees for things like medical care and the general cost of confinement.
  3. Finally, when a person is released, they often receive a release card, a prepaid debit card that contains money they had when entering prison, money they earned while locked up, and money they had in their trust account. These cards are rife with fees — many of them unavoidable — that quickly drain the money on the card and line the pockets of the companies that administer these programs.

People increasingly recognize this cycle of exploitation is morally problematic and makes poverty — one of the main drivers of criminalized behavior — worse. That’s why some government agencies are increasingly cracking down on this behavior, and through our research and advocacy, we’re pressuring more states to join them.

We encourage you to check out the piece to understand better how the cycle of exploitation works. If you’re looking for more details and state-specific data, check out our work exposing exploitation in the criminal legal system.


In the toolkit, we share tips and lessons we’ve learned over two decades of using data, visuals, and narratives to expose the harms of mass incarceration.

by Mike Wessler, March 2, 2022

Today, we’re launching our new Advocacy Toolkit, a collection of guides and training materials that advocates can use to strengthen their campaigns to end mass incarceration. The toolkit builds on lessons we’ve learned from our two decades of work to improve our criminal legal system. It provides skills-based guides on accessing public records, securing and organizing data, crafting persuasive narratives, and creating impactful visuals. It also includes issue-based guides on protecting in-person visits in prisons and jails, opposing jail expansion, and ending prison gerrymandering. We plan to add additional resources in the future.

Our new advocacy department created this toolkit as part of our expanded effort to support the people and groups on the ground doing the hard work to end mass incarceration.

While most advocacy departments organize campaigns, mobilize volunteers, and pressure decision-makers for change, ours is a bit different. We’re not looking to replicate the amazing work that thousands of people and hundreds of organizations are already doing to reform the criminal legal system. Instead, as a research organization known for using data visualizations and easy-to-understand narratives, our advocacy work aims to help these organizations leverage our expertise to strengthen their campaigns. That’s why our advocacy department will focus on:

  • connecting state and local movement partners and decision-makers to data that can fuel their campaigns for criminal justice reform;
  • identifying and filling gaps where new research would support reform efforts;
  • producing training materials, like the Advocacy Toolkit, for use by criminal justice reform advocates; and
  • providing technical assistance, including identifying reform opportunities (such as our annual list of winnable state criminal justice reforms), giving messaging support, offering expert review of documents and legislation, and connecting partners working in similar spaces.

We hope these new resources will help to strengthen the movement to end mass incarceration. If you use the Toolkit in your work, tell us about it. Let us know what worked, what didn’t, and what other resources we can provide. And, if you’re an organization seeking assistance from our new advocacy department, drop us a line to let us know how we can help.

Election officials in Massachusetts need to ensure voting access for people in jail.

by Jenny Landon, October 2, 2020

The vast majority of people held in Massachusetts jails maintain the right to vote, but they are often de facto disenfranchised because of a lack of access to voting systems and voter registration.

We’ve joined a coalition of organizations across the state calling on the Secretary of the Commonwealth to secure access to the ballot for people who are eligible to vote but face barriers because they are in jail. You can read the full letter we signed on to here, which outlines in detail the specific barriers faced by people detained or serving sentences in Massachusetts jails.

S.2846 will make phone calls free of cost for incarcerated people and their families in Massachusetts.

by Jenny Landon, September 4, 2020

The Prison Policy Initiative joined a coalition of over 100 organizations, legal service providers, public defenders, social workers, and directly impacted people to sign on to a letter urging the Massachusetts State Legislature to pass S.2846, a bill that would make phone calls free of cost for incarcerated people and their families.

The burden of expensive phone calls overwhelmingly falls on family members, especially on women: in Massachusetts, families pay $24 million per year to stay connected to their incarcerated loved ones, and a national study found that the cost will put one in three families into debt. Black and brown people in Massachusetts are disproportionately criminalized and targeted by police, so expensive phone calls to correctional institutions disproportionately strip money out of the pocketbooks of families of color.

Before the pandemic hit, more than 50 percent of families with an incarcerated loved one struggled to pay for basic housing and food needs. With the economic hardship brought on by COVID-19, it is now urgent that Massachusetts stops subsidizing our exploitative and expensive carceral system with regressive costs that fall on the most impoverished in the state.

In Massachusetts, there are thousands of people held in jails pre-trial because they cannot afford bail, and their phone calls are the most expensive of all incarcerated people in the state. When people can’t get together the funds to get out of jail, exorbitant phone rates only make a difficult time even harder. Not only do people held pre-trial need to coordinate childcare or elder care, make arrangements for missing work, have prescriptions brought to the facility, or simply have someone to talk to while incarcerated, they also have to organize their defense.

People detained pretrial are more likely to plead guilty just to get out of jail, more likely to be convicted, and more likely to get longer sentences. Costly phone calls play a central role in this injustice by limiting how often and how long pretrial detainees can talk to their families and friends in the service of their defense. As a result, pretrial detainees often present a weaker defense than they would have if they had been able to make calls freely. On a systemic level, high phone rates from jails hurt indigent defendants by draining already-scarce resources from public defenders’ offices.

As written in the full letter:

As a result of the work of Black organizers, constituents across the Commonwealth understand that no-cost calls are about keeping families together. People should not be forced to pay for a lifeline, nor the programs offered by the DOC and county facilities. It is unconscionable that in this moment a mother is forced to choose between buying groceries and talking to her incarcerated child or that a child would need to forego hearing his incarcerated mother’s voice when they most need comfort. The Commonwealth must intervene to ensure that corporations can no longer profit from lines of communication that are critical to creating the support networks necessary for success upon reentry. We respectfully ask you to pass S. 2846 this session!

For these reasons and many more, we urge the Massachusetts State Legislature to pass S.2846. Are you in Massachusetts and want to support this bill? Call your representatives and senators!
