The Intensity of the Rwandan Genocide: Measures from the Gacaca Records

Marijke Verpoorten

This article illustrates how fine continuous and categorical measures of genocide intensity can be derived from the records of the Rwandan transitional justice system. The data, which include the number of genocide suspects and genocide survivors across 1484 administrative sectors, are highly skewed and contain a non-negligible number of outlying observations. A number of genocide proxies are subjected to Principal Component Analysis (PCA) to obtain a genocide index, and the effect of survival bias on this index is reduced by augmenting the set of genocide proxies subjected to PCA with the distance from an administrative sector to the nearest mass grave. Finally, the administrative sectors are divided into distinct categories of low, moderate and high genocide intensity by means of Local Indicators of Spatial Auto-Correlation (LISA) that allow identifying significant high-high and low-low clusters of genocide intensity.
