NEW: We map where people in #Montana prisons come from, going (where possible) down to the neighborhood level. This is the 12th installment in our series of reports about the geography of mass incarceration. #MTNews #MTPol /1
ICYMI, we also have reports about:
California
Colorado
Connecticut
Delaware
Maryland
Nevada
New Jersey
New York
Pennsylvania
Virginia
Washington

See them here: prisonpolicy.org/origin/
Our reports include download-able data tables of incarceration data by city, county, zip code, Census tract, state legislative district, and more.

The reports give researchers the data they need to study how incarceration tracks with other indicators of community health.
Why these 12 states? These are the states that have ended the practice of #prisongerrymandering. Ending prison gerrymandering requires (for complicated reasons) creating accessible tables of anonymized residence data for incarcerated people.
Prison gerrymandering is the practice of drawing state or city legislative districts around large prisons and pretending that the people inside are legitimate constituents. It should be abolished everywhere. We have a whole website about it here:
prisonersofthecensus.org
Your state could be the next to end prison gerrymandering and open up a world of scholarship.

A growing body of research shows that mass incarceration's greatest impact on voting does not happen via felony disenfranchisement laws. More often, not voting is the collateral damage of someone being punished by the state, or seeing their loved ones punished.
Even going to jail for a very short time for a misdemeanor makes someone less likely to vote after release - "either by changing their attitudes or by making their life sufficiently difficult that they couldn’t make it to the polls," 2019 research shows.

New research from @publicsafetylab confirms that, yes, jail incarceration is making people less likely to vote who *would probably have voted* if they had never gone to jail.

For many people on probation and parole, traveling out of state for abortion care is already next to impossible. 🧵
On any given day in the U.S., 666,413 women are on probation or parole. In many jurisdictions — eg Louisiana, Tennessee, Kentucky, Idaho, & Texas — it’s common for people on probation and parole to face restrictions on where they can travel.
They also often face restrictions on with whom they can “associate” (including, potentially, people who assist in coordinating abortion access, where such help is criminalized). All of these restrictions will make it harder for people under supervision to get abortion care.

Outside of prisons, the U.S. has a handle on hepatitis C. Yet in prisons, where it’s MUCH more likely to be found, states miss a huge opportunity to make public health strides with this infectious disease. Here are some key takeaways about the carceral hepatitis C crisis: Image
An estimated 30% of all people living with hepatitis C pass through correctional facilities every year. Yet, a 2015 survey showed that a mere 16% of prisons tested everyone for hepatitis C antibodies upon admission.
hcvguidelines.org/references/mau…
Another survey of state corrections departments showed that, of the over 100,000 people in state prisons known to be infected with hepatitis C on the last day of 2014, less than 1 percent were being treated for it.

NEW REPORT: The U.S. allows children — especially Black children — to grow up in poverty. With new demographic data, we can see more clearly how many of those kids grow up to fill state prisons. Here’s a short thread about the data.
About 1 in 10 people in state prison today was homeless before turning 18.

1 in 5 was in public housing before 18.

1 in 5 was in foster care.

For Black incarcerated people, the numbers are higher.
And the younger someone is when they’re arrested for the first time, the more likely they are to have also been homeless, in public housing, in foster care, or for their family to have received public assistance before they turned 18.

NEW: We’ve just released the 2022 edition of Mass Incarceration: The Whole Pie - the most comprehensive, up-to-date view of who is locked up in the U.S., where, and why: prisonpolicy.org/reports/pie202…

This report shows huge drops in prison and jail populations. Why? Thread.
First, the key #s from our report:
- ~1.9 million people are locked up in the U.S. today.
- Prison populations fell ~16% during the pandemic.
- Local jail populations fell about 13%.
It’s easy to read these #s as saying the pandemic sparked widespread criminal justice reform. It didn’t. COVID-19 jammed the gears of the criminal justice system, making it harder for various parts of the system to move.

Incarcerated men at Rikers are on strike protesting terrible conditions, chiefly a lack of access to medical care. The strike is news, but the problems at Rikers aren't new, nor unique to NYC...
16 people died at Rikers last year. That's consistent with a trend of rising jail deaths across the country: prisonpolicy.org/blog/2021/06/2…
And new @BJSgov data show that deaths in state/federal prisons increased 46% in 2020, even as prisons released fewer people:
