The Methodology of “Varieties of Democracy” (V-Dem)1

This article describes and discusses the new generation of methodological responses to measuring democracy and related issues generated by Varieties of Democracy (V-Dem). V-Dem is distinct in several regards in addition to its unique level of disaggregation, by the combination of: historical data extending back to 1900 and for a large selection among them to 1789 for many countries in the world; use of multiple, independent coders for each evaluative question; inter-coder reliability tests incorporated into a custom designed Bayesian item-response theory measurement model; provision of confidence bounds for all point estimates associated with expert-coded questions as well as for all indices; multiple indices reflecting varying theories of democracy; fully transparent aggregation procedures; and that all data are made freely available, including original coder-level judgments (exclusive of any personal identifying information)

Varieties of Democracy (V-Dem) is a new approach to conceptualizing and measuring democracy. We provide a multidimensional and disaggregated dataset that reflects the complexity of the concept of democracy as a system of rule that goes beyond the simple presence of elections. The V-Dem project distinguishes between five high-level principles of democracy: electoral, liberal, participatory, deliberative, and egalitarian, and collects data to measure these principles. V-Dem draws on theoretical and methodological expertise from its worldwide team to produce data in the most objective and reliable way possible. Approximately half of the indicators in the V-Dem dataset are based on factual information obtainable from offcial documents such as constitutions and government records. The other half consists of evaluative indicators on topics like political practices and compliance with de jure rules. On such issues, typically five experts provide ratings. V-Dem works closely with leading social science research methodologists and has developed a state of the art Bayesian Item Response Theory measurement model that, to the extent possible, minimizes coder error and addresses issues of comparability across countries and over time. V-Dem also draws on the team’s academic expertise to develop theoretically informed techniques for aggregating indicators into mid- and high-level indices. In this sense, V-Dem is at the cutting edge of developing new and improved methods of social science measurement.Varianter på demokrati (V-Dem) är ett internationellt forskningsprojekt vars syfte är att ta fram nya indikatorer på demokrati, i alla världens länder från år 1789 fram till idag. V-Dem erbjuder ett nytt sätt att konceptualisera och mäta demokrati, och särskiljer mellan fem demokratiprinciper: val-, liberal-, deltagar-, deliberativ- och jämlikhetsdemokrati, och samlar in data för att mäta dessa
