Authoritarian Regime Type Dataset Dataverse

This dataset is an updated and extended version of the widely used Wahman, Teorell, and Hadenius (WTH) (2013) dataset on autocratic regime types. While maintaining the original WTH framework, this update introduces a new democracy threshold based on the V-Dem Electoral Democracy Index (EDI) and provides novel regime classifications for the period 1946-2024, providing a reliable tool for analyzing long-term autocratic trends, regime transitions, and shifts between autocracy and democracy.
