How Predictive Policing Reinforces Bias
Algorithmic tools like PredPol were supposed to reduce bias. But HRDAG has found that racial bias is baked into the data used to train the tools.
El Salvador 1991 – Who Did What To Whom?
Members of the Salvadoran military committed tens of thousands of killings during the country’s civil war which raged from the late 1970’s until 1990. While working for a peace organization in El Salvador in 1991, Patrick Ball was asked by a colleague at a human rights group to help organize a large collection of human rights testimonies. Trained as a social scientist, Ball created the “Who Did What To Whom” (WTWTW) model for examining human rights data. Ball used this system to create a structured, relational database of violations reported in more than 9,000 testimonies to the Salvadoran Human Rights Commission.
To determine who was most ...
Quantitative Research at the AHPN Guatemala
In early 2006 I joined the Historical Archive of the National Police (Archivo Histórico de la Policía Nacional, or AHPN) without knowing the impact it would have on my future. I started with cleaning, organizing and classifying documents—and learning, with other colleagues, what a historical archive is and how it works.
By April of that year, parallel to these learning processes, I was selected along with 20 other people to begin work on the challenging Quantitative Research project. I started as a "coder," transferring key content from documents into a database. (more…)

Data integration and statistical estimation: A collaboration with the Colombian Truth Commission (CEV) and the Special Jurisdiction for Peace (JEP)
Colombia and the guerrilla of the Revolutionary Armed Forces of Colombia (FARC) reached a Peace Agreement in 2016, which created the Commission for the Clarification of the Truth, Coexistence and Non-Repetition (CEV). The objective of this temporary institution was to discover the truth of what happened in the context of the armed conflict.

Timor-Leste
During the violence in Timor-Leste in June 2006, armed gangs broke into the offices of the Commission for Reception, Truth and Reconciliation (CAVR) in Dili and stole their motorbikes.
The Human Rights Data Analysis Group, then at Benetech®, and other human rights observers wondered whether the mobs would soon return to loot the irreplaceable paper records used by the CAVR to compile their definitive report entitled "Chega!"
The Benetech Initiative contributed to the CAVR findings and released a separate statistical report (PDF) establishing that at least 102,800 (+/- 11,000) Timorese died as a result of human rights violations in Timor-Leste ...

Using Cemetery Information to Search for the Disappeared Lessons from a Pilot Study in Rionegro, Antioquia, Colombia
Between May and July 2009, researchers from the Benetech Human Rights Data Analysis Group (HRDAG) conducted a pilot study to examine patterns of information about unidentified bodies at a cemetery in Rionegro, a town located Antioquia, Colombia. The study was carried out to support ongoing efforts by HRDAG's partner organization EQUITAS (Colombian Interdisciplinary Team for Forensic Work and Psychosocial Assistance) to identify bodies of unknown persons in the Rionegro cemetery. EQUITAS has found that cemeteries in ...

New UN report counts 191,369 Syrian-war deaths — but the truth is probably much, much worse
Amanda Taub of Vox has interviewed HRDAG executive director about the UN Office of the High Commissioner of Human Right’s release of HRDAG’s third report on reported killings in the Syrian conflict.
From the article:
Patrick Ball, Executive Director of the Human Rights Data Analysis Group and one of the report's authors, explained to me that this new report is not a statistical estimate of the number of people killed in the conflict so far. Rather, it's an actual list of specific victims who have been identified by name, date, and location of death. (The report only tracked violent killings, not "excess mortality" deaths from from disease or ...
A better statistical estimation of known Syrian war victims
Researchers from Rice University and Duke University are using the tools of statistics and data science in collaboration with Human Rights Data Analysis Group (HRDAG) to accurately and efficiently estimate the number of identified victims killed in the Syrian civil war.
…
Using records from four databases of people killed in the Syrian war, Chen, Duke statistician and machine learning expert Rebecca Steorts and Rice computer scientist Anshumali Shrivastava estimated there were 191,874 unique individuals documented from March 2011 to April 2014. That’s very close to the estimate of 191,369 compiled in 2014 by HRDAG, a nonprofit that helps build scientifically defensible, evidence-based arguments of human rights violations.

Training with HRDAG: Rules for Organizing Data and More
I had the pleasure of working with Patrick Ball at the HRDAG office in San Francisco for a week during summer 2016. I knew Patrick from two workshops he previously hosted at the University of Washington’s Centre for Human Rights (UWCHR). The workshops were indispensable to us at UWCHR as we worked to publish a number of datasets on human rights violations during the El Salvador Civil War. The training was all the more helpful because the HRDAG team was so familiar with the data. As part of an impressive career which took him from Ethiopia and Kosovo to Haiti and El Salvador among others, Patrick himself had worked on gathering and analysing ...
