The dataset allows researchers to adopt a new approach to studying governing elites in autocracies and democracies. We provide bibliographic information, such as gender and party affiliation, on cabinet members in July of each year in the period from 1966 to 2016 in all countries with a population of over 400,000 citizens. In total, the dataset contains data on 50,197 cabinet members in 177 countries, totaling 8,057 country-years. WhoGov makes it possible to answer questions like; what is the proportion of women cabinet members globally, what type of regime has the highest cabinet turnover and have cabinets increased in size over time? And many more. The dataset is highly flexible and can be used to calculate countless variables of interest, including the number of female ministers, ministerial experience, cabinet turnover and cabinet size at the country level per year. The team is continuously working on updating the data with more years and more variables. For questions or if you identify any errors, please contact: whogov@nuffield.ox.ac.uk.
