This study, a collection of crossnational measures of political democracy, contains over 800 variables for most of the world's independent countries. Political, social, and economic measures are available in the data file, and topics include adult suffrage, civil liberties, political rights, the openness, fairness, and competitiveness of the electoral process, executive and legislative selection and effectiveness, political party legitimacy, political participation, limitations on the executive branch of the government, level of democratization, economic openness, constitutional development, government legitimacy, and the outlook for freedom. A series of variables focuses on freedom and barriers to freedom, including freedom of peaceful assembly and association, mail censorship, women's rights, freedom of information and technology, freedom of political opposition, and freedom of the press. Compulsory membership in state organizations and political parties and compulsory religion in schools are addressed as well.
