Reference excerpt

The Democracy Indices by V-Dem are democracy indices published by the V-Dem Institute that describe qualities of different democracies. It is published annually. 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.

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.

By country The authors of the V-Dem Institute's "Democracy Report 2026" state that the views and opinions expressed in the report are their own and do not reflect an official position of the larger V-Dem Project, the V-Dem Steering Committee, or the V-Dem Institute. The table below shows 2026 V-Dem Democracy indices describing the year 2025.

Regimes of the World

V-Dem maintains the Regimes of the World index, which classifies governments using data from its other indices as either a closed autocracy, electoral autocracy, electoral democracy, or liberal democracy. It is heavily inspired by Robert Dahl's theory of polyarchy based on six institutional guarantees: elected officials, free and fair elections, freedom of expression, alternative sources of information, associational autonomy, and inclusive citizenship.

Autocracies

Regimes where leaders are not de facto accountable to citizens and may lack multiparty or free and fair elections. Dahl's institutional prerequisites are not fulfilled.

Closed Autocracy

Governments which lack multiparty elections for the chief executive or the legislature, or lack any competition such as in one-party states. Legislative institutions are de facto undermined and electoral accountability is evaded.

Electoral Autocracy

Governments where the chief executive, legislature, or both are accountable in de jure multiparty elections. They fall short of democratic standards due to irregularities, limitations on party competition, and violations of Dahl's prerequisites. They are closely related to theories of electoral authoritarianism and competitive authoritarianism.

Democracies Regimes with de facto multiparty, free and fair elections. Dahl's institutional prerequisites are at least minimally fulfilled.

Electoral Democracy Regimes that possess the bare minimum to be considered a democracy. They are "de-facto accountable to citizens through periodic elections", but are not liberal democracies and lack further entrenched individual and minority rights beyond the electoral sphere. Basic electoral democracies may not possess a fully developed rule of law, legislative and judicial oversight of the executive branch, protections against the "tyranny of the majority", and only minimal fulfillment of Robert Dahl's institutional prerequisites for democracy. Liberal Democracy

Regimes that possess the rule of law and satisfy liberal principles. They provide checks and balances between legislative and judicial oversight of the executive branch, limitations on government to prevent the "tyranny of the majority", protect individual liberties, and provide equal access to and protection under the law. A fully developed rule of law is essential for liberal democracies, as it ensures decisions are implemented. It is sometimes referred to as a "Madisonian" democracy.

Digital Society Project The Digital Society Project is a subset of indicators on V-Dem's survey that asks questions about social media's political status and the internet. Specifically, the Digital Society Project measures a range of questions related to internet censorship, misinformation online, and internet shutdowns. This annual report includes 35 indicators assessing five areas: disinformation, digital media freedom, state regulation of digital media, the polarization of online media, and online social cleavages. It has been updated each year starting in 2019, with data covering from 2000–2021. Similar to other expert analyses like Freedom House, these data are more prone to false positives when compared with remotely sensed data, such as that from Access Now or the OpenNet Initiative.

Worked examples

Example 1 — a first encounter with V-Dem Democracy Indices

Start with the simplest possible case. Write down what V-Dem Democracy Indices claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to V-Dem Democracy Indices before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about V-Dem Democracy Indices ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of V-Dem Democracy Indices

In research: V-Dem Democracy Indices appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses V-Dem Democracy Indices in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: V-Dem Democracy Indices is common in secondary-school and first-year university syllabi. It links to neighbouring topics Democracy, Democracy promotion, International rankings, so understanding it makes those chapters shorter.
In everyday life: Look for V-Dem Democracy Indices outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
