World Political Cleavages and Inequality Database (WIL)
The World Political Cleavages and Inequality Database (WPID) is the result of a collaborative research program involving about twenty researchers all around the world. The central aim is to provide open and convenient access to the most extensive available dataset on the structure of political cleavages and social inequalities in electoral democracies, located on the five continents, from the mid-20th century to the present.
This databse is managed by the World Inequality Lab (WIL).
