Data and codebook for the updated EPR-O data. It includes 86 countries covering the years from 1946 to 2019 or 2000 - 2019 for the additional countries. The original EPR-Organizations dataset (see Supplementary Material at https://doi.org/10.1177/0022002721996436 ) includes 40 countries covering the years from 1946 to 2013. We extend this data in two ways: 1. We expand the time coverage for previously coded countries for the years 2014 - 2019 2. We add new countries with a temporal coverage of the years from 2000 - 2019 For more information on the dataset consider the cited sources as well as the codebook.
