We believe truth leads to accountability, and at HRDAG, promoting accountability for human rights violations is our highest purpose.

Projects
The Human Rights Data Analysis Group is a non-profit, non-partisan organization that applies rigorous science to the analysis of human rights violations around the world. As scientists, we work to support our partners—the advocates and human rights defenders who “speak truth to power”—by producing unbiased, scientific results that bring clarity to human rights violence and by ensuring that the “truth” is the most accurate truth possible.

Our work at HRDAG is organized into three areas:

  1. Basic Research and Development - We invent and extend scientific methods so that we can better understand patterns of mass violence.
  2. Creation of Knowledge - We help to establish a scientifically defensible historical record of human rights abuses, including publishing public reports and providing expert testimony in war crimes trials.
  3. Education and Outreach - Through speaking engagements, publications, and training graduate students, we help those working in the human rights community to better understand the role and power of statistical data and reasoning.

Syria

In 2012, at the request of the United Nations Office of the High Commissioner for Human Rights (OHCHR), HRDAG undertook a comparison of seven datasets documenting killings in Syria. Based on this analysis, we found 59,648 unique, identifiable records of killings between March 2011 and November 2012.   Read more.

US Police Killings

In early March, the Bureau of Justice Statistics published a report estimating that from 2003 to 2009 and 2011, there were approximately 7427 US homicides committed by police. We responded that the method the analysts used, capture-recapture with two databases, is vulnerable to underestimation.   Read more.

Guatemala

In 1996, a peace accord brokered by the United Nations ended 36 years of internal armed conflict in Guatemala. During the hostilities, non-governmental organizations asked for technical support from the scientific community in the project to gather the experiences and of witnesses and victims in databases for statistical analysis.

Chad

Hissène Habré’s rule over Chad (1982-1990) was marked by allegations of systematic torture and crimes against humanity. Habré claims that he was not aware of violations committed by the Documentation and Security Directorate, the state security force that pursued political opponents and operated prisons.   Read more.
     

Inaccurate statistics can damage the credibility of human rights claims—and that’s why statistics about human rights violations must be as scientifically accurate as possible.
