Democracy indices arequantitative andcomparative assessments of the state ofdemocracy[1] for different countries according to various definitions of democracy.[2]
The democracy indices differ in whether they are categorical, such as classifying countries into democracies,hybrid regimes, andautocracies,[3][4] or continuous values.[5] The qualitative nature of democracy indices enables data analytical approaches for studyingcausal mechanisms of regime transformation processes.
Democracy indices vary in their scope and the weight assigned to different aspects of democracy. These aspects include the breadth and strength of core democratic institutions,freedom of expression, the competitiveness and inclusiveness ofpolyarchy, governance quality, adherence to democratic norms, co-option of opposition, and other related factors, such aselectoral system manipulation,electoral fraud, and popular support of anti-democratic alternatives.[6][7][8]
The Economist Democracy Index, by the UK-basedEconomist Intelligence Unit, is an assessment of countries' democracy. Countries are rated asfull democracies,flawed democracies,hybrid regimes, orauthoritarian regimes. The index is based on five categories measuring pluralism, civil liberties, and political culture.[11]
TheV-Dem Democracy Indices, by theV-Dem Institute, distinguishes between five high-level principles of democracy: electoral, liberal, participatory, deliberative, and egalitarian, and quantifies these principles.[12] The V-Dem Democracy indices include theCitizen-initiated component of direct popular vote index, which indicates the strength of direct democracy and thepresidentialism index, which indicates higher concentration of political power in the hands of one individual.
TheBertelsmann Transformation Index, by theBertelsmann Stiftung, evaluates the development status and governance of political and economic transformation processes on the path to constitutional democracy and a market economy for developing and transition countries around the world. Bertelsmann Transformation Index categorizes countries into: hard-line autocracy, moderate autocracy, very defective democracy, defective democracy, and consolidating democracy.[13]
The Global State of Democracy Indices, by theInternational Institute for Democracy and Electoral Assistance, assesses democratic performance using different types of sources: expert surveys, standards-based coding by research groups and analysts, observational data and composite measures.[14]
TheElectoral Integrity Project surveys academics on the perceived electoral integrity of countries and subnational entities
TheFragile States Index, formerly the Failed States Index, is an annual report that aims to assess states' vulnerability to conflict or collapse, ranking all sovereign states with membership in the United Nations where there is enough data available for analysis.[17]
TheGallagher index measures an electoral system's relative disproportionality between votes received and seats in a legislature.[18]
ThePedersen index is a measure of political volatility in party systems.
TheDemocracy Ranking was a democracy ranking by the Association for Development and Advancement of the Democracy Award.[22]
ThePolity data series contains annual information on regime authority characteristics and covers the years 1800–2018 based on competitiveness, openness, and level of participation, sponsored by thePolitical Instability Task Force (PITF).[23]
Lexical Index of Electoral Democracy (LIED) by Skaaning et al. democracy's characteristics assessed with easy-to-observe characteristics, few evaluations by own researchers based on academic research, and evaluating whether necessary characteristics are present.[25]
Democracy is a multifaceted concept encompassing the functioning of diverse institutions, many of which are challenging to measure. As a result, limitations arise in quantifying and econometrically analyzing democracy's potential effects or its relationships with other phenomena, such as inequality, poverty, and education. etc.[29] Given the challenges of obtaining reliable data on within-country variations in aspects of democracy, much of the academic focus has been on cross-country comparisons. However, significant variations in democratic institutions can exist within individual countries, highlighting the limitations of such an approach. Another dimension of the difficulty in measuring democracy lies in the ongoing debate between minimalist and maximalist definitions of democracy. A minimalist conception of democracy defines democracy by primarily considering the essence of democracy; such as electoral procedures.[30] A maximalist definition of democracy can include outcomes, such as economic or administrative efficiency, into measures of democracy.[31] Some aspects of democracy, such as responsiveness[32] oraccountability, are generally not included in democracy indices due to the difficulty measuring these aspects. Other aspects, such asjudicial independence or quality of theelectoral system, are included in some democracy indices but not in others.
Some measures of democracy, such as Freedom House and Polity IV, adopt a maximalist understanding of democracy by analyzing indicators that extend beyond mere electoral procedures. These measures aim to capture broader dimensions of democratic governance, reflecting a more comprehensive view of political systems.[33] These measures attempt to gauge contestation and inclusion; two features Robert Dahl argued are essential in democracies that successfully promote accountable governments.[34][35] The democratic rating given by these mainstream measures can vary greatly depending on the indicators and evidence they deploy.[36] The definition of democracy utilized by these measures is important because of the discouraging and alienating power such ratings can have, particularly when determined by indicators which are biased toward Western democracies.[37]
Dieter Fuchs and Edeltraud Roller argue that accurately measuring the quality of democracy requires complementing objective metrics with subjective measurements that reflect the perspectives and experiences of citizens.[38] Similarly, Quinton Mayne and Brigitte Geißel also defend that the quality of democracy does not depend exclusively on the performance of institutions, but also on the citizens' own dispositions and commitment.[39]
Data on democracy, and particularly global indices of democracy, and the data they rely on, have been the subject of scrutiny and criticized by various scholars.Gerardo L. Munck and Jay Verkuilen for instance, have raised concerns about the methodologies used by prominent democracy indices such as Freedom House and Polity, such as the concept of democracy they measured, the design of indicators, and the aggregation rule.[40] Political scientists Andrew T. Little and Anne Meng "highlight measurement concerns regarding time-varying bias in expert-coded data" such as Freedom House and V-Dem and encourage improving expert-coding practices.[41] Knutsen et al.[42] did not see evidence for time-varying bias in their expert-coded data and note the application ofitem response theory,factor analysis and estimates of uncertainties to limit expert biases while discussing concerns inoperationalization of observer-invariant measures of democracy.
