Version 1.0 (2019) provides data on 201 TMK episodes for the period 1946-2017 with annualised information on perpetrator intent, severity, targeted groups and a host of additional variables. It includes a pre-coded ordinal indicator of TMK that aggregates evidence of intent and severity into a 7-point scale and a new binary indicator of genocide and politicide that can serve as an alternative to existing measures. Users are able to construct their own indicators from the dataset, based on their research questions or preferred definitions.
