The unit of analysis for each record in this structure is VIOLATION.
Each violation was of a particular type, happened at a particular time and place, and was committed by zero, one, or several organizational perpetrators. The violation was committed against zero or one named (individually identified) victim, and zero or more anonymous (unidentified) additional victims. The violation was reported one or more times in one, two, or three source types.
Note that to count the number of times individuals suffered particular violations, users should sum either the ...
The datasets contributed by 30+ organizations do a wonderful job of tallying the violence that was observed—but they don’t account for the violence that nobody witnessed or documented.
If we could glean key missing information from those fields, we would be able to use more records.

In early March, the Bureau of Justice Statistics published a report that estimated that in the period 2003-2009 and 2011, there were approximately 7427 homicides committed by police in the US. We responded that the method the analysts used, capture-recapture with two databases, is vulnerable to underestimation if the databases exhibit positive dependence. We conduct a thorough sensitivity analysis on the original independence model as applied to the police homicides databases. We used information from several other countries where our partners created multiple databases of homicides. We ...
When working with documents in an archive, every document offers the opportunity for statistical study and quantitative research. But a document can also offer the discovery of a story. That is the case with the disappearance of Ana Lucrecia Orellana Stormont, who was reported missing on June 6, 1983, at the age of 35.
Ana Lucrecia, a professor of psychology at the University of San Carlos, was scheduled to attend a meeting with Edgar Raúl Rivas Rodríguez at the Plaza Hotel in Guatemala’s capital city. Edgar, who also went missing, was a teacher at the School of Political Science at the University. (Ana Lucrecia’s case is explained more fully ...
It’s inevitable that databases will have information gaps, and special care must be taken to account for these gaps.

NEW STUDY DOCUMENTS HISSÈNE HABRÉ’S OVERSIGHT OF POLICE PRISONS WHERE THOUSANDS DIED
10th Anniversary of Indictment of Chad Ex-Dictator
January 29, 2010, N’Djamena, Chad and Palo Alto, CA, U.S. - On the 10th anniversary of the first indictment of Hissène Habré in Senegal, the Benetech Human Rights Data Analysis Group (HRDAG) released a new study showing that the former Chadian dictator was well informed of the hundreds of deaths that occurred in prisons operated by his political police. This information could be critical in the long delayed prosecution of Habré who has been accused of killing and systematically torturing thousands of politi...
Excerpt from the article: The estimate is based on reports from four organizations investigating deaths in Syria from March 15, 2011, to December, 31, 2015. From those cases, the Human Rights Data Analysis Group identified 12,270 cases with sufficient information to confirm the person was killed in detention. Using a statistical method to estimate how many victims they do not yet know about, the group came up with 17,723 cases.
Almost a quarter century ago, on November 16, 1989, six Jesuit scholars, their housekeeper and her 15-year-old daughter were massacred inside the University of Central America (UCA) in San Salvador, El Salvador. Their chief target was the rector of the country’s leading university. The murders were carried out by members of the elite Atlacatl Battalion, acting on the direct orders of the highest-ranking members of the Salvadoran military. The United Nations–sponsored Truth Commission for El Salvador found that members of the Salvadoran military's high command “gave...the order to kill Father Ignacio Ellacuría and to leave no witnesses.” ...
Paula Amado and María Juliana Durán Fedullo reflect on how the Truth Commission may change Colombia’s history, finally officially acknowledging the 50-year conflict and its casualties, and reckoning with who did what to whom.
The report tries to answer the question of whether a particular risk assessment model reinforces racial inequalities in the criminal justice system.
HRDAG has published a report about the 500 Tamils who disappeared while in Army custody in Sri Lanka in 2009.
