Replication data for: Democratic Electoral Systems Around the World, 1946-2000

A clear and consistent classification of the electoral institutions used in these elections is followed by a concise geographical and temporal analysis. The worldwide focus of the data set reveals several striking patterns.

For example, there have been almost as many elections under dictatorship as there have been under democracy. Other patterns include the fact that presidential regimes nearly always employ proportional electoral formulas, absolute majority rule has become the worldwide norm for electing presidents, and nonmajoritarian systems have become more complex due to the increasing use of multiple tiers and mixed electoral formulas.
