Better Life Index is an interactive comparative tool developed to measure well-being and quality of life across countries. It presents composite information on multiple dimensions of living standards, enabling users to compare nations on health, wealth, environment, and civic life using customizable weights. Conceived and maintained by an international policy institution, the Index has been cited in academic studies, policy debates, and media coverage as an alternative to purely economic indicators.

Overview

The Index was launched by the Organisation for Economic Co-operation and Development to complement gross domestic product measures with multidimensional assessments of societal outcomes. It aggregates data drawn from OECD statistical collections, national statistical offices such as Statistics Canada and Australian Bureau of Statistics, and international agencies including the World Health Organization and the International Labour Organization. The interactive platform invites users—from researchers at University of Oxford or Harvard University to journalists at The Economist or policymakers at European Commission—to assign importance to different dimensions, producing bespoke country comparisons. The tool has been featured alongside other initiatives like the Human Development Index by the United Nations Development Programme and the World Happiness Report coordinated by researchers at Columbia University.

Methodology

Methodologically, the Index adopts a weighted aggregation approach underpinned by the OECD’s statistical protocols and metadata standards. It combines standardized indicators after normalization procedures similar to those used in composite indices produced by World Bank research units and the United Nations Statistical Division. Weights are either equal by default or user-specified, allowing incorporation of preferences analogous to frameworks used in social choice theory from scholars at London School of Economics and Princeton University. Indicator selection and data sourcing follow transparency guides used by International Monetary Fund analytic products and peer review processes like those at National Bureau of Economic Research. Quality assurance includes checks against microdata from surveys administered by institutions such as Eurostat and national censuses.

Indicators and Dimensions

The Index organizes life into several headline dimensions that parallel established welfare and public policy domains observed in reports by World Health Organization and United Nations Educational, Scientific and Cultural Organization. Core dimensions include material living standards, housing, employment, income, health status, education outcomes, environmental quality, subjective well-being, community and civic engagement, safety, and work–life balance. Each dimension is represented by one or more indicators—for example, life expectancy figures from World Health Organization databases, employment rates recorded by International Labour Organization, and educational attainment metrics informed by Organisation for Economic Co-operation and Development surveys. The Index aligns with indicator taxonomies used in comparative frameworks like the Global Burden of Disease study and the OECD.Stat portal.

Country Profiles and Rankings

Country profiles present time-series and cross-sectional snapshots for member and partner countries, using formats familiar to users of country briefs produced by World Bank and United Nations Development Programme. Rankings are sensitive to user-defined weights; a country ranking highly under a weight favoring income might differ from one prioritized for environment or health. The platform covers many OECD member countries—such as United States, Germany, Japan, United Kingdom, France—and extends to partner economies like Brazil and China in particular datasets. Comparative use cases appear in policy reports by bodies like the European Council and analyses by think tanks including Brookings Institution and Chatham House.

Uses and Reception

Academics use the Index in empirical research at institutions like Massachusetts Institute of Technology and University of Cambridge to explore correlations between social policies and outcomes. Non-governmental organizations, including Amnesty International and Oxfam, have referenced its dimensions when advocating for social investments. Journalists at outlets such as BBC and The Guardian have used interactive exports to illustrate stories on well-being. National ministries of finance and social affairs across countries including Sweden and Canada have cited Index components when designing indicator suites for national wellbeing strategies. International forums—such as meetings at the Organisation for Economic Co-operation and Development and sessions of the United Nations General Assembly—have discussed the role of multidimensional metrics in sustainable development debates.

Criticisms and Limitations

Critiques focus on indicator selection, weighting flexibility, and comparability. Some scholars at University of California, Berkeley and Yale University argue the Index’s reliance on available administrative and survey data leads to uneven coverage between high-income and lower-income countries, echoing concerns raised in critiques of the Human Development Index. Methodological debates draw on literature from RAND Corporation on composite indicator robustness and from analysts at International Institute for Environment and Development regarding environmental measures. Others note that user-defined weights introduce subjectivity that can obscure normative implications, a point discussed in conferences at American Economic Association. Finally, comparability over time may be affected by revisions in source datasets produced by agencies such as Eurostat and the World Health Organization.
