Quantitative Analysis of Deaths and Disappearances

Over the years, PRIMA’s members have partnered with organizations in Colombia, Sri Lanka, Timor-Leste, and Punjab, India, that have sought to quantify the extent of forced disappearances and killings. A critical component of this work has been based on triangulation from multiple data sources, such as testimony, cemetery records, and household surveys, and use of multiple complementary measurement approaches such as multiple systems estimation and survey-based estimations. Such analyses, developed in partnership with local human rights institutions, have been used to counter denials that large-scale lethal violence took place. They have also provided population-level descriptions of the demographic profile of the victims of such violence. In Timor-Leste, the analysis showed that more civilians died due to famine, whereas deaths of members of the armed resistance and of political parties were more likely to result from killings and disappearances. In Colombia, Tamy Guberek and Daniel Guzman worked on several projects using statistical estimations to determine that lethal violence was significantly under-registered, and therefore, undercounted. In India, Romesh used adaptive survey-design methods to tap into the social networks of the families of the disappeared to generate more comprehensive enumeration of victims of lethal violence during Punjab’s counterinsurgency period (1984–1995).
