CSP - Center for Systemic Peace
The CSP runs the Polity IV project, which codes political systems of countries with an index value between -10 and 10 for the years 1800 to 2017. Values between -10 and 6 represent autocracies, values between -5 and 5 for anocracies, and values higher than 6 represent democracies. The index value is calculated from six components, one of which is the selection of the executive officers or political competition.
