Varieties of Democracy (V-Dem) Research ProgramThe study of democracy and democratization lies at the center of political science and is increasingly important in economics, sociology, and history. In the post-Cold War world, democracy has also become a central foreign policy objective. Yet, there is little conclusive evidence about why some countries become and remain democratic and others do not. The Varieties of Democracy (V-Dem) Research Program sets out to provide the first comprehensive theory of democratization, that also accounts for the multiple core principles and values in the varieties of democracy: electoral, liberal, majoritarian, consensual, participatory, deliberative, and egalitarian democracy. V-Dem also breaks down each core principle index into its constituent components, about 50 of them measured separately. The V-Dem Database will contain data on these for all countries of the world, annually from 1900 to the present including pre-independence eras. Being the first to use this unique database and by bringing together a research team consisting of leading democratization-scholars in the world, each with their unique set of expertise and area-competence, we aim to provide cutting-edge, systematic and theoretically revolutionizing examination of democratization. This research program is an international team-based collaboration.
