Human Rights Data Analysis Group

The Human Rights Data Analysis Group (HRDAG) is a United States-based non-profit and non-partisan organization focused on using rigorous data analysis to document human rights violations. Rather than operating as a conventional advocacy, relief, or monitoring organization, HRDAG works at the intersection of statistics, data science, epidemiology, and human rights research. Its central contribution is the development and application of methods that can estimate patterns of killing, disappearance, displacement, and other abuses when available records are incomplete, biased, or deliberately suppressed. The organization was established in December 1991 by Patrick Ball as part of the Science and Human Rights Program of the American Association for the Advancement of Science. Its early work helped establish a model in which quantitative analysis could be used to support investigations into mass violence and state abuses. On November 3, 2003, HRDAG moved under the non-profit umbrella organization Benetech. It later became an independent non-profit on February 1, 2013, with Community Partners serving as its fiscal sponsor. HRDAG has undertaken or published analysis concerning conflicts and political violence in a wide range of countries and territories, including Syria, Colombia, Chad, Kosovo, Guatemala, Peru, East Timor, India, Liberia, Bangladesh, and Sierra Leone. Its work commonly addresses the limitations of casualty lists, witness accounts, administrative records, and survey data. By comparing sources and modeling missing or undercounted cases, the organization seeks to produce estimates that are more transparent and defensible than simple counts drawn from incomplete documentation. The group has also participated in legal proceedings. It provided expert testimony in war-crimes trials involving Slobodan Milošević and Milan Milutinović before the International Criminal Tribunal for the former Yugoslavia. In Guatemala, HRDAG-related analysis was used in proceedings before the country's Supreme Court in the trial of General José Efraín Ríos Montt, the de facto president from 1982 to 1983. Ríos Montt was found guilty of genocide and crimes against humanity, although the legal history of that case subsequently included significant procedural developments. In more recent work, HRDAG has published analysis of police violence in the United States. Across its projects, the organization presents data analysis as a means of improving the factual record available to researchers, courts, commissions of inquiry, journalists, and affected communities. Its positioning is therefore that of a specialist research and expert-analysis institution whose value lies in methodological rigor, independence, and the ability to make hidden or disputed patterns of abuse measurable.

Human Rights Data Analysis Group was founded in December 1991 by Patrick Ball within the Science and Human Rights Program of the American Association for the Advancement of Science. Its creation reflected an effort to bring formal scientific and statistical methods into the documentation of abuses that were often recorded unevenly or concealed by authorities. The organization developed a role distinct from ordinary human rights reporting: it used quantitative techniques to assess the scale and distribution of violence, while making the limits and uncertainty of the underlying evidence explicit. Over time, HRDAG conducted research across numerous conflict and post-conflict settings. Its published findings addressed violence in Syria, Colombia, Chad, Kosovo, Guatemala, Peru, East Timor, India, Liberia, Bangladesh, and Sierra Leone. These projects generally dealt with problems such as incomplete victim lists, duplicated records, missing documentation, and the difficulty of inferring the true scale of violence from surviving evidence. HRDAG's analytical approach has included the comparison and integration of multiple datasets and the use of statistical estimation to identify patterns that conventional counting may miss. The organization's work also entered judicial and accountability processes. HRDAG provided testimony in proceedings at the International Criminal Tribunal for the former Yugoslavia involving Slobodan Milošević and Milan Milutinović. It also contributed analysis to proceedings before Guatemala's Supreme Court in the trial of General José Efraín Ríos Montt, who was found guilty of genocide and crimes against humanity. These engagements demonstrated how statistical evidence can complement witness testimony, documentary records, and forensic investigation in cases involving large-scale or systematic abuses. On November 3, 2003, HRDAG moved to the non-profit umbrella company Benetech. This arrangement placed the organization within a broader technology and social-impact framework while allowing it to continue its specialized research mission. On February 1, 2013, HRDAG became an independent nonprofit organization and was fiscally sponsored by Community Partners. In its later work, HRDAG expanded or continued its focus on contemporary violence, including police violence in the United States. Its overall history is marked by continuity in method rather than by a consumer product portfolio or commercial expansion: the organization has remained centered on independent analysis, transparent quantitative reasoning, and the use of evidence to support human rights accountability. Its work is intended for courts, commissions, researchers, journalists, civil-society groups, and communities seeking a more reliable account of violence and abuse.

A specialist, independent research organization that applies data science and statistical methods to human rights documentation, accountability, and legal proceedings.

• Research and analytical services

  Human rights data analysis

  HRDAG analyzes records of killings, disappearances, and other abuses to estimate the scale and characteristics of human rights violations. Its work is designed for situations where official records are incomplete, politically distorted, or unavailable. The organization uses statistical reasoning and comparisons among sources to produce evidence that can support research, public reporting, and accountability processes.

• Legal and accountability support

  Expert testimony and litigation support

  The organization contributes quantitative expertise to legal and investigative proceedings involving mass violence and state abuse. Its work has included testimony at the International Criminal Tribunal for the former Yugoslavia and analysis used in Guatemala's Supreme Court proceedings concerning General José Efraín Ríos Montt. This offering translates complex population-level evidence into material usable by courts and other accountability institutions.

• Reports and studies

  Human rights research publications

  HRDAG publishes research findings and methodological work concerning violence in conflict, post-conflict, and domestic policing contexts. Its geographic portfolio has included Syria, Colombia, Chad, Kosovo, Guatemala, Peru, East Timor, India, Liberia, Bangladesh, Sierra Leone, and the United States. Publications aim to clarify what the available evidence can establish and where uncertainty remains.
