Liberia

In July 2009, The Human Rights Data Analysis Group (HRDAG) concluded a three-year project with the Liberian Truth and Reconciliation Commission to help clarify Liberia's violent history and hold perpetrators of human rights abuses accountable for their actions. (This work was conducted by HRDAG while with Benetech.) In the course of this work, HRDAG analyzed more than 17,000 victim and witness statements collected by the Liberian Truth and Reconciliation Commission and compiled the data into a report entitled "Descriptive Statistics From Statements to the Liberian Truth and Reconciliation Commission." The report is included as an annex to the final ...

Timor-Leste FAQs

How do you know that there are more conflict-related deaths than have been reported to the Commission for Reception, Truth and Reconciliation (CAVR, by its Portuguese acronym)? Where did the method of multiple systems estimation come from? If you didn't have access to the whole population, how do you know how representative these data are of the entire population? i.e. How do you control for bias? What are the total conflict-related mortality numbers? How many people were killed and disappeared between 1974 and 1999? And how many people died due to hunger and illness? What is the margin of error associated with these results? What is ...

Colombia

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).

FAQ about the JEP-CEV-HRDAG data integration and statistical estimation project

    1. Is there a single source of information about the victims of the armed conflict in Colombia? No. Colombia has an extensive documentation process for victims of the armed conflict. Hundreds of institutions, victims' organizations, and civil society organizations have focused their efforts on recording this information. However, each entity or organization develops their documentation process with its own limitations related to technical, logistical, social, and missionary capacities. No entity or organization is able to document the complete universe of victims. This is because it is impossible for them to reach every part of the country, ...

USA

HRDAG’s analysis and expertise continues to deepen the national conversation about police violence and criminal justice reform in the United States. In 2015 we began by considering undocumented victims of police violence, relying on the same methodological approach we’ve tested internationally for decades. Shortly after, we examined “predictive policing” software, and demonstrated the ways that racial bias is baked into the algorithms. Following our partners’ lead, we next considered the impact of bail, and found that setting bail increases the likelihood of a defendant being found guilty. We then broadened our investigations to examine ...

Revisiting the analysis of event size bias in the Iraq Body Count

(This post is co-authored by Patrick Ball and Megan Price) In a recent article in the SAIS Review of International Affairs, we wrote about "event size bias," the problem that events of different sizes have different probabilities of being reported. In this case, the size of an event is defined by the number of reported victims. Our concern is that not all violent (in this case homicide) events are recorded, that is, some events will have zero sources. Our theory is that events with fewer victims will receive less coverage than events with more victims, and that a higher proportion of small events will have zero sources relative to large events. The ...

De nombreuses allégations crédibles de torture systématique et de crimes contre l’humanité ont été faites contre la Direction de Documentation et de Sécurité (DDS), les forces de l’ordre responsables pour la persécution d’adversaires du régime Habré qui étaient aussi responsables pour l’administration de nombreuses prisons durant ce régime. “La Piscine” est une ancienne piscine qui a été couverte par un toit en béton. Il est allégué qu’il s’agissait là d’une des prisons de la DDS dans laquelle de nombreux ...

Chad – Photo Essay

[français] Hissène Habré was president of the former French colony of Chad from 1982 to 1990. Credible allegations of systematic torture and crimes against humanity have been made against Habré’s state security force, the Documentation and Security Directorate (DDS), which pursued political opponents and operated notorious prisons during his regime. One prison where the DDS is alleged to have tortured prisoners is the “Piscine,” a former swimming pool covered by a concrete roof. Prisoners were held in ten dank cells where witnesses say they were starved and abused. After being forced from power in 1990, Habré went into exile ...

Preguntas frecuentes sobre el proyecto JEP-CEV-HRDAG de integración de datos y estimación estadística

¿Hay una fuente de información única sobre las víctimas del conflicto armado en Colombia? No. Colombia cuenta con un amplio proceso de documentación de víctimas del conflicto armado. Cientos de entidades, organizaciones de víctimas y organizaciones de la sociedad civil han focalizado sus esfuerzos en registrar la información. Sin embargo, cada entidad u organización desarrolla este proceso con las limitaciones propias de capacidades técnicas, logísticas, sociales y de misionalidad, lo que conduce a que ninguna entidad ni organización logre documentar el universo completo de víctimas.  Esto se debe a que les es imposible llegar a ...

Guatemala

Collecting and Protecting Human Rights Data in Guatemala (1991-2013) 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 of witnesses and victims in databases. From 1993 to 1999 Dr. Patrick Ball, then at the American Association for the Advancement of Science (AAAS), worked with the International Center for Human Rights Research in Guatemala (CIIDH) to collect and organize evidence of more than 43,000 human rights violations. The ...

Syria

On the heels of the Arab Spring revolutions, which began in December 2010, armed conflicts began in Syria in March 2011. What started as protests demanding that President Bashar al-Assad resign resulted in the deployment of the Syrian Army to stop the uprising. Since then, violent conflict has been raging in Syria. Amid this continuing violence and humanitarian crisis, local human rights activists and citizen journalists risk their lives to document human rights violations. The grave challenges they face are compounded by the regime's active suppression of information flow out of the country. As a result, there is considerable uncertainty about the ...

Chad

Hissène Habré's rule over the former French colony of Chad, from 1982 to 1990, was marked by numerous and credible allegations of systematic torture and crimes against humanity. Habré claims that he was not aware of violations committed by the Documentation and Security Directorate (DDS), the state security force that pursued political opponents and operated notorious prisons during his regime. In January 2010, the Human Rights Data Analysis Group (HRDAG) released a new study showing that Habré was well informed of the hundreds of deaths that occurred in prisons operated by the DDS. The HRDAG report, State Coordinated Violence in Chad under ...

If you'd like to support HRDAG in this project, please consider making a donation via Our Donate page. Over the last year, HRDAG has deepened the national conversation about homicides by police, predictive policing software, and the role that bail plays in the criminal justice system. Our studies describe how the racial bias inherent in police practice becomes data input to predictive policing tools. In another project, we are shining light on the iniquities of bail decisions.

Multiple Systems Estimation: Does it Really Work?

<< Previous post, MSE: Stratification and Estimation Q15. Are there other MSE models one might use with human rights data? Q16. Is it possible to use MSE to model non-lethal human rights violations? Q17. I am concerned about using MSE with my data, because the datasets were gathered by opposing organizations. Victims who were reported to an NGO were very unlikely to be reported to state sources, but also very likely to be reported to religious organizations. Won't that cause the overlaps between the NGO list and the state list to be artificially low, and the overlaps between the NGO list and the church list to be artificially high? Does ...
