Through Polity, Representative democracy and Liberal democracy

Datasets analyze 251 indices and consist of 531 specific indicators (which are a set of fixed, multiple choice survey questions) focusing on both qualitative and quantitative measurements of democracy. These survey questions were carefully developed and adjusted during a concept and planning phase from 2008 to 2013, before the project officially went live with annual data collection in 2014. V-Dem utilizes historical data dating back to the 1800s for some countries, multiple coders for each question, and large measurement models. They use several key principles: electoral, liberal, majoritarian, consensual, participatory, deliberative, and egalitarian, with variables describing various aspects of government, especially on the quality of democracy, inclusivity, and other economic indicators. In 2025, the V-Dem index had 531 indicators and 251 high-level indices covering 202 polities from the period of 1789–2025. As of 2026, 74% of the world is under authoritarian rule.

The indices have faced criticism concerning the design and aggregation of indicators, potential time-varying bias in expert-coded data, and the reliance on expert assessments and methods used to estimate and limit associated uncertainties.

Core indices

As of 2026, the V-Dem Institute published 531 indicators along with 251 indices and 62 other indicators. V-Dem publishes five core indices with several other supplementary indices. The core indices are measuring "electoral", "liberal", "participatory", " deliberative" and "egalitarian" "democracies".

Electoral Democracy Index

This index measures the principle of electoral or representative democracy, including whether elections were free and fair, as well as the prevalence of a free and independent media. This index is part of all the other indices as a central component of democracy.

Liberal Democracy Index

This index incorporates measures of rule of law, checks and balances, and civil liberties along with the concepts measured in the electoral democracy index.

Participatory Democracy Index

This index measures the degree to which citizens participate in their own government through local democratic institutions, civil society organizations, direct democracy, and the concepts measured in the electoral democracy.

Deliberative Democracy Index

This index measures the degree to which decisions are made in the best interest of the people as opposed to due to coercion or narrow interest groups, in addition to the basic electoral democracy index.

Egalitarian Democracy Index

This index measures the level of equal access to resources, power, and freedoms across various groups within a society, in addition to the level of electoral democracy.
