Based on the International IDEA database of postwar elections, which covers 171 independent states, 1,129 parliamentary elections and 360 presidential elections, this site is a useful resource for anyone studying voting trends internationally or in specific countries or regions. The site includes an overview (Global Survey) of postwar trends and specific data for each nation covered. This data is accessed via interactive maps or via country listings for parliamentary and presidential elections. Data includes year, total vote, registration, turnout percentages, and population size. The date at which each country's data was last updated varies. The main IEA site offers a number of publications and other resources related to the promotion of democracy.
