Perceived Mass Atrocities Dataset

The Perceived Mass Atrocities Dataset (PMAD) is a country-year measure of atrocities with accompanying narratives. Built to support the US Congress’s Elie Wiesel Genocide and Atrocities Prevention Act of 2018, PMAD enables the systematic comparison of the occurrence and magnitude of seven atrocity types, in addition to group-perpetrated violence against women and LGBTQIA+ groups, with aggregate atrocities indices for 195 countries from 2018 onward. PMAD offers a foundation for quantitative studies of atrocities as well as more qualitative, process-focused research of lethal and less-lethal violence with its single, divisible framework.
