In this paper, we aim at developing specific methodological and analytical instruments for evaluating how democratic regions have developed different institutional structures and how these variations can impact on their public policy capabilities. We start by mapping the existing dedicated indicators for measuring the quality of democracy at subnational level. We then take stock and compare a broad range of primary (existing) data concerning the dynamics of political regimes at different territorial levels (including also World Bank, Policy IV, Freedom House, Quality of Government, RAI, Democratic Decay, and WZB Democracy Barometer datasets.
