Varieties of Democracy (V-Dem) is a large international effort to measure hundreds of features of democracy for all countries and colonies in the world from 1900 to the present. V-Dem is also capturing democracy in a much broader sense than any existing indices do: not only electoral and liberal aspects but participatory, egalitarian, consensual, majoritarian, and deliberative dimensions. Thus, rather than using a single standard for democracy, we measure multiple versions of democracy that are widely understood around the globe.
V-Dem is already one of the largest dataset on democracy with some 15 million data points, available to researchers, policy-makers, and advocates across the world. Online analysis of democracy data is already available via the project website: https://v-dem.net
