Unified Democracy Scores

Data source: Pemstein, Meserve and Melton

The Unified Democracy Scores (UDS) covers the time period 1946-2012. These scores incorporate updates to three of the ten original measures - Freedom House (2014), Polity IV (Marshall et al., 2012), and Van Hanen (2012) - that feature in the analysis that the authors report in their 2010 article. In addition, the most recent release added a recently developed measure of democracy - Economist Intelligence Unit (2012) - to its framework.
