Democratic Electoral Systems around the world, 1946–2011

This research note describes an update to Golder's (2005)Democratic Electoral Systems (DES) dataset. We extend the temporal scope of the original dataset by including all legislative and presidential elections that took place in democratic states from 2001 to 2011. In addition to significantly expanding the size of the DES dataset, we offer a simplified classification scheme for electoral systems. We also provide more detailed information about all democratic elections since 1946, including the dates for each round of elections as well as the rules used in different electoral tiers. A brief temporal and geographic overview of the data is presented.
