Deportation Possible for El Salvador’s Gen. García – Supported by HRDAG Analysis
Gen. José Guillermo García, El Salvador’s defense minister from 1979 to 1983, may be deported from Florida to El Salvador because of his involvement in war crimes that occurred under his command. The recommendation comes from a Miami immigration judge, whose decision was supported with expert testimony from Stanford political science professor Terry Karl, who presented extensive statistical analysis of killings, disappearances, kidnappings, torture and other crimes under Gen. García’s watch. The statistical analysis was a joint effort between Professor Karl and Amelia Hoover Green and Patrick Ball of Human Rights Data Analysis Group (HRDAG). ...
Updated Casualty Count for Syria
Today the United Nations Office of the High Commissioner for Human Rights (OHCHR) released an HRDAG-prepared report that describes and tallies documented killings in the Syrian Arab Republic from the beginning of the conflict in March 2011 through April 2014. (The report is here.) This is our third report for the UN on the Syrian conflict, and it is an update of work we published in January 2013 and June 2013.
The report, Updated Statistical Analysis of Documentation of Killings in the Syrian Arab Republic, concludes that approximately 191,000 identifiable victims have been reported in the period covered (March 2011 – April 2014). (more…)
Evaluation of the Kosovo Memory Book
At the end of 2014 we completed the evaluation of the Kosovo Memory Book database and are pleased to conclude that the database has succeeded in documenting all or nearly all the human losses during conflicts in Kosovo during the period from 1998 to 2000.
With a motto of "Let people remember people," the goal of the Kosovo Memory Book (KMB) is to document all people who were killed or disappeared in connection with the war in Kosovo. The project aimed to document all human losses during armed conflict in the territory of the Former Yugoslav Republic (FYR) between 1998 and 2000.
The KMB database evaluation is the fruition of several years of ...

Rise of the racist robots – how AI is learning all our worst impulses
“If you’re not careful, you risk automating the exact same biases these programs are supposed to eliminate,” says Kristian Lum, the lead statistician at the San Francisco-based, non-profit Human Rights Data Analysis Group (HRDAG). Last year, Lum and a co-author showed that PredPol, a program for police departments that predicts hotspots where future crime might occur, could potentially get stuck in a feedback loop of over-policing majority black and brown neighbourhoods. The program was “learning” from previous crime reports. For Samuel Sinyangwe, a justice activist and policy researcher, this kind of approach is “especially nefarious” because police can say: “We’re not being biased, we’re just doing what the math tells us.” And the public perception might be that the algorithms are impartial.
How Pretrial Risk Assessment Tools Perpetuate Unfairness
Tools like Compas allegedly help judges predict future criminal activities and eliminate bias. HRDAG and partners showed how the tools recycle bias.
Primer to Inform Discussions about Bail Reform
The primer addresses what pretrial risk assessment is and what the research supports.

Megan Price: Life-Long ‘Math Nerd’ Finds Career in Social Justice
“I was always a math nerd. My mother has a polaroid of me in the fourth grade with my science fair project … . It was the history of mathematics. In college, I was a math major for a year and then switched to statistics.
I always wanted to work in social justice. I was raised by hippies, went to protests when I was young. I always felt I had an obligation to make the world a little bit better.”

El Salvador
Some of the earliest large-scale human rights information projects happened in El Salvador. One was developed by Patrick Ball at the Salvadoran non-governmental Human Rights Commission, also known as Comision de Derechos Humanos de El Salvador (CDHES-ng). Between 1977 and 1990, more than 9,000 testimonies were taken in an effort to document the nature and scope of the bloody conflict between the army and the Farabundo Marti National Liberation Front (FMLN). Starting in 1991, Patrick worked with CDHES staff to organize the information in an early computer database. They linked reported human rights violations with the career structures of individual ...
