| Tiivistelmä≠ | Varieties of Democracy (V-Dem) is a measurement project that captures democracy as a multidimensional concept rather than a single score. Set out by Coppedge, Gerring, and colleagues (2011), V-Dem distinguishes five principles of democracy — electoral, liberal, participatory, deliberative, and egalitarian — and measures them from hundreds of specific indicators coded by multiple country experts. A statistical measurement model aggregates these expert ratings into disaggregated indicators and high-level indices, each accompanied by estimates of measurement uncertainty, producing one of the most detailed and transparent democracy datasets available. | Polity score analysis uses the Polity dataset to measure and compare the regime characteristics of states on a continuum from full autocracy to full democracy. Maintained by the Center for Systemic Peace (Marshall and Gurr), Polity codes institutional features — how chief executives are recruited, the constraints on their authority, and the openness of political competition — into separate democracy and autocracy indices that combine into a single polity score from −10 to +10. It is one of the most widely used measures of regime type in comparative politics and international relations. |
