ProPublica: A Legacy of High-Impact Investigative Journalism
ProPublica has established itself as a powerhouse of non-profit investigative journalism, specializing in stories that hold powerful institutions accountable. By combining deep-dive reporting with sophisticated data analysis, the organization tackles systemic failures in the legal system, healthcare, government, and corporate sectors.
From uncovering judicial bias to mapping toxic pollution, ProPublica's work often leads to real-world policy changes, legal actions, and prestigious accolades, including multiple Pulitzer Prizes.

Criminal Justice and Legal Accountability
A significant portion of ProPublica's portfolio focuses on the flaws within the American legal system, ranging from police misconduct to algorithmic bias.
The COMPAS Algorithm Investigation
In 2016, ProPublica investigated COMPAS, a software tool used by U.S. courts to predict recidivism (the likelihood of a defendant committing another crime). Led by Julia Angwin, the study found significant racial bias: Black defendants were nearly twice as likely as white defendants to be incorrectly labeled as high-risk, while white defendants were more likely to be labeled low-risk despite re-offending. Additionally, only 20% of those predicted to commit violent crimes actually did so. While the developer, Northpointe, and the Community Resources for Justice contested the findings, the report sparked a global conversation on AI bias.
Juvenile Justice in Rutherford County
A 2021 collaboration with Nashville Public Radio revealed systemic abuse in Rutherford County, Tennessee. The investigation found that Judge Donna Scott Davenport directed the charging of children under non-existent laws. While the statewide incarceration rate for children referred to juvenile court was 5%, Rutherford County's rate was a staggering 48%. This work was a finalist for the 2022 National Magazine Awards.
Serial Rape Investigation
T. Christian Miller and Ken Armstrong collaborated on a report detailing the discovery of a serial rapist across Colorado and Washington. This piece won the 2016 Pulitzer Prize for Explanatory Reporting and served as the basis for the 2019 Netflix series Unbelievable.
Public Health and Environmental Safety
ProPublica uses data to expose risks that are often hidden from the general public, particularly in healthcare and industrial pollution.
Industrial Air Pollution Mapping
In 2021, ProPublica analyzed billions of rows of EPA data to create the first neighborhood-level map of industrial pollution. The project identified over 1,000 toxic hotspots, estimating that 250,000 people were exposed to unacceptable cancer risks. Notable findings included Verona, Missouri, where risk was 27 times the acceptable limit, and Longview, Texas, where the area near the Texas Eastman Chemical Plant showed a risk 72 times higher than acceptable levels. Following the report, the EPA agreed to install air monitors in Verona.
Healthcare Accountability
The organization has targeted corporate negligence in healthcare, such as its investigation into Psychiatric Solutions. The report, published with the Los Angeles Times, detailed how the Tennessee-based company profited by cutting staff at failing hospitals, leading to patient deaths and facility closures, including Manatee Palms Youth Services in Florida.
Additionally, the 2015 Surgeon Scorecard provided an interactive database of complication rates for eight common elective procedures. Despite criticism from some doctors and a critique by RAND, statisticians like Andrew Gelman supported the effort to make medical outcomes more transparent.
Wealth, Power, and Civil Rights
ProPublica continues to investigate the intersection of money and power, as well as the protection of marginalized communities.
Taxation of the Ultra-Wealthy
In June 2021, using leaked IRS documents, ProPublica reported that the wealthiest Americans pay significantly lower tax rates than the middle class when unrealized capital gains are viewed as income. A notable example was investor Peter Thiel, who grew a tax-free Roth IRA to over $5 billion. This leak led to a Justice Department investigation, resulting in Charles E. Littlejohn pleading guilty to unauthorized disclosures in 2023.
Civil Rights and Repatriation
The Documenting Hate project, launched in 2017, systematically tracks hate crimes and bias incidents, allowing victims to submit stories and partnering with newsrooms like the Minneapolis Star Tribune. More recently, The Repatriation Project (2023) exposed the delays in returning Native American remains and cultural items under the Native American Graves Protection and Repatriation Act (NAGPRA), earning Mary Hudetz the Richard LaCourse Award in 2024.
Collaborative Journalism and Corrections
ProPublica extends its reach through the Local Reporting Network, launched in 2018. By subsidizing salaries for reporters at over 70 local news organizations—including the Idaho Statesman and The Salt Lake Tribune—they amplify local impact. A partnership with the Anchorage Daily News won the 2020 Pulitzer Prize for Public Service.
The organization also maintains journalistic integrity through public corrections. In 2018, ProPublica retracted part of a 2017 report regarding Gina Haspel's role in a Thai "black site," clarifying that she did not take control of the site until after the interrogation of Abu Zubaydah had ended.

Frequently Asked Questions
What is the Local Reporting Network?
Launched in 2018, it is a partnership with over 70 local news organizations where ProPublica subsidizes the salary and benefits of reporters to strengthen local investigative journalism.
How did ProPublica's pollution map affect the EPA?
After ProPublica identified that Verona, Missouri, had a cancer risk 27 times the acceptable limit, the EPA agreed to install three air monitors to track ethylene oxide concentrations in the area.
What was the finding regarding the COMPAS software?
The investigation found that Black defendants were almost twice as likely as white defendants to be labeled high-risk but not actually re-offend, while white defendants were more likely to be labeled low-risk but go on to commit crimes.
What is NAGPRA and how does it relate to ProPublica's work?
NAGPRA is the Native American Graves Protection and Repatriation Act of 1990. ProPublica's Repatriation Project exposed institutional resistance from museums and universities in returning Native American remains and cultural items.
Why did ProPublica retract part of the Gina Haspel report?
The organization corrected its 2017 report to clarify that Gina Haspel did not take control of the Thai black site until after the interrogation of Abu Zubaydah had already concluded.
