Legatum Prosperity Index
The Legatum Prosperity Index is an annual global ranking produced by the Legatum Institute that measures the prosperity of 167 countries—covering over 99% of the world's population—by evaluating the conditions enabling residents to flourish beyond mere wealth accumulation.[1] It defines prosperity as encompassing opportunity, freedom, and thriving, assessed through 300 country-level indicators drawn from public data sources.[2] First published in 2007 following foundational research with Oxford University academics, the index serves as a policy tool to identify drivers of national success and guide improvements in human flourishing.[3] The index employs a framework of 12 pillars organized into three domains: inclusive societies (covering safety, governance, social capital, and personal freedom), open economies (including investment environment, enterprise conditions, infrastructure, market access, and economic quality), and empowered people (encompassing living conditions, health, education, and natural environment).[2] These pillars aggregate 67 policy-focused elements, providing granular insights into structural factors like rule of law, innovation, and environmental sustainability that causally contribute to sustained prosperity.[1] Countries are scored holistically, with Nordic nations such as Denmark, Sweden, Norway, and Finland consistently leading due to strong performances in governance, social cohesion, and personal freedoms, while revealing declines in areas like the United States' social capital and safety metrics in recent editions.[4] By tracking longitudinal trends since its inception, the index highlights global prosperity plateaus amid rising authoritarianism and economic stagnation, emphasizing empirical evidence for reforms in institutions and policies that foster individual agency and societal resilience over redistributive or ideologically driven interventions.[5] The Legatum Institute, now rebranded as the Prosperity Institute under the Legatum Group—a private philanthropic entity—positions the index as a non-partisan resource for leaders, prioritizing data integrity over prevailing academic or media narratives that may undervalue foundational principles like property rights and limited government.[3]
Introduction
Definition and Objectives
The Legatum Prosperity Index (LPI) is an annual report published by the Legatum Institute, an independent think tank, that ranks 167 countries—representing 99.4% of the global population—on their levels of prosperity using a multidimensional framework. Unlike GDP-centric measures, the LPI assesses prosperity as encompassing not only economic wealth but also wellbeing, personal freedoms, social cohesion, and institutional quality, drawing on over 300 indicators across 12 pillars such as safety and security, personal freedom, governance, social capital, investment environment, enterprise conditions, infrastructure, market access, economic quality, living conditions, health, and education.[6][7][8] The core objective of the LPI is to serve as a diagnostic tool for understanding and advancing national prosperity by revealing how countries progress or regress in creating conditions for human flourishing. It aims to inform evidence-based policymaking by identifying causal factors—such as effective governance and inclusive economic opportunities—that correlate with sustained improvements in living standards, while highlighting barriers like weak rule of law or limited personal freedoms.[7][9][10] Ultimately, the Index seeks to drive societal transformation by emphasizing prosperity as a state where individuals have the opportunity and agency to thrive, supported by robust institutions and entrepreneurial ecosystems, rather than mere material accumulation. This approach underscores the Legatum Institute's view that prosperity measurement should prioritize empirical outcomes in human potential realization over ideological narratives.[9][11]Historical Origins
The Legatum Prosperity Index emerged from initiatives by the Legatum Group, a private investment firm, to quantify national prosperity through a multidimensional lens that extends beyond gross domestic product to include social and institutional factors. In 2006, Legatum commissioned a team of Oxford University professors to develop foundational metrics and a conceptual model for prosperity, aiming to identify evidence-based drivers of national success and quality of life.[11] The project culminated in the establishment of the Legatum Institute in 2007, initially tasked with producing the Index as an annual assessment tool. The inaugural edition, released that year, analyzed 50 countries with available high-quality data, examining underlying causes of disparities in economic growth, personal freedom, health, education, and governance to inform pathways out of poverty.[11][12] From its inception, the Index emphasized empirical measurement of prosperity's components, drawing on diverse data sources to track progress and highlight policy-relevant insights, with subsequent iterations expanding geographic coverage and methodological rigor to encompass up to 167 nations by the 2020s.[13][14]Organizational Context
Legatum Institute's Role
The Legatum Institute, a London-based think tank established in 2007 by the Legatum private investment group, holds primary responsibility for the creation, annual production, and dissemination of the Legatum Prosperity Index.[11][3] Its foundational work on the Index began in 2006 through collaboration with Oxford University professors to develop metrics for prosperity that extend beyond gross domestic product to encompass growth, opportunity, freedom, and responsibility.[11][3] The Institute's core objective in maintaining the Index is to serve as a transformational tool for policymakers and leaders, evaluating 167 countries—covering over 99% of the global population—across 12 pillars, 67 elements, and approximately 300 indicators derived from public data sources.[1] These assessments highlight drivers of national flourishing, including economic strength, governance, social capital, and personal safety, to identify policy levers for enhancing wellbeing and reducing poverty.[1][11] Funded entirely by Legatum since its inception, the Institute applies an evidence-based approach informed by historical and empirical analysis to promote institutional reforms and cultural values that sustain prosperity, positioning the Index as a benchmark referenced by entities such as the World Economic Forum.[3][11] By tracking longitudinal trends since the Index's 2007 launch, the organization aims to guide nations toward inclusive societies and open economies while emphasizing individual empowerment over aggregate wealth metrics.[1][11]Evolution to Prosperity Institute
The Legatum Institute, established in 2007 by the Legatum Group—a Dubai-based private investment firm founded by New Zealand-born billionaire Christopher Chandler—was initially tasked with developing and publishing the Legatum Prosperity Index as a measure of national prosperity beyond mere GDP.[11] The institute's early work centered on compiling the index annually, drawing on data across multiple domains to assess 167 countries, with the goal of informing policy through empirical insights into factors like economic quality, governance, and social capital.[7] Over the subsequent years, the institute broadened its scope beyond index production to include research programs, fellowships, and advocacy aimed at advancing the underlying principles of prosperity, such as free enterprise, rule of law, and personal freedoms, often through publications and events hosted in London.[15] By the mid-2010s, the institute had evolved into a think tank hosting initiatives like the Legatum Center for Development and Entrepreneurship at MIT and collaborative funds for humanitarian relief, reflecting a shift toward practical applications of prosperity metrics in global development and crisis response.[11] This expansion aligned with Legatum Group's philanthropic mission to foster well-being worldwide, but it also diluted the institute's original index-focused identity amid growing emphasis on broader ideological promotion of market-oriented reforms.[16] The 2023 Prosperity Index, for instance, incorporated refined methodologies to track post-pandemic recovery and policy impacts, underscoring the institute's maturation into a data-driven policy influencer.[2] On January 21, 2025, the Legatum Institute underwent a formal rebranding to the Prosperity Institute, a change announced by Legatum to more accurately encapsulate its matured mission of not only measuring but actively advancing and protecting the ideas underpinning national prosperity.[17] The rebranding did not alter the institute's operational structure or funding from Legatum but emphasized a renewed commitment to countering threats to prosperity principles, such as regulatory overreach and declining social cohesion, through targeted research and global outreach.[18] This evolution positions the Prosperity Institute as an independent entity within the Legatum ecosystem, continuing to steward the index while prioritizing causal analysis of prosperity drivers over descriptive rankings alone.[19]Methodological Framework
Core Pillars and Domains
The Legatum Prosperity Index structures its evaluation of national prosperity through three overarching domains—Inclusive Societies, Open Economies, and Empowered People—each encompassing four pillars, for a total of 12 pillars. These pillars aggregate 67 policy-focused elements, which in turn draw from over 300 indicators sourced from more than 70 international datasets, enabling a multifaceted assessment of conditions conducive to human flourishing beyond mere GDP metrics.[2][7] Inclusive Societies domain emphasizes societal foundations that foster security, liberty, effective rule, and communal bonds. The Safety & Security pillar quantifies risks from conflict, terrorism, violent crime, and property crime, capturing both immediate threats and enduring instability.[2] The Personal Freedom pillar evaluates adherence to legal rights, civil liberties, and tolerance toward diverse groups, including religious and political freedoms.[2] Governance assesses institutional integrity through metrics on executive constraints, policy implementation efficacy, and corruption prevalence in public sectors.[2] Finally, Social Capital measures interpersonal trust, family and community networks, voluntary associations, and civic engagement levels.[2] Open Economies domain focuses on economic frameworks that promote innovation, investment, and trade efficiency. Investment Environment examines investor protections, financial system stability, and ease of capital access.[2] Enterprise Conditions gauges regulatory burdens on business formation, operational competition, and innovation incentives.[2] Infrastructure & Market Access evaluates physical and digital connectivity, logistics performance, and barriers to trade such as tariffs or subsidies.[2] Economic Quality tracks macroeconomic stability, employment rates, productivity, and poverty reduction dynamics.[2] Empowered People domain addresses individual capabilities and environmental sustainability. Living Conditions assesses access to housing, sanitation, nutrition, and digital services affecting daily welfare.[2] Health incorporates healthcare availability, disease prevalence, life expectancy, and system resilience.[2] Education covers enrollment rates, learning outcomes, skill development from early childhood through adulthood, and equity in access.[2] Natural Environment considers air and water quality, biodiversity preservation, climate vulnerability, and resource management impacts on habitability.[2] This domain-level grouping underscores the Index's premise that prosperity emerges from interdependent societal, economic, and human elements.[7]Indicators, Data Sources, and Measurement
The Legatum Prosperity Index comprises 300 country-level indicators organized into 67 policy-focused elements across 12 pillars, which are further grouped into three domains: Inclusive Societies, Open Economies, and Empowered People.[2] These indicators measure aspects of prosperity beyond traditional economic metrics, incorporating factors such as safety perceptions, rule of law, educational attainment, and environmental sustainability, selected for their statistical reliability, international coverage across 167 countries, and alignment with drivers of long-term productive capacity as informed by academic literature and input from over 100 experts.[8] Indicators are categorized as objective (e.g., homicide rates, secondary school enrollment) or subjective (e.g., generalized trust from surveys, satisfaction with governance), with selection prioritizing publicly available data that exhibits temporal stability and policy relevance.[20] Data for these indicators are sourced from over 70 providers, emphasizing reputable international bodies to ensure comparability and minimize bias in reporting. Primary sources include the World Bank for economic and poverty metrics, Gallup for subjective well-being and social perceptions, the World Justice Project for rule-of-law assessments, the World Economic Forum for business environment evaluations, UNESCO for education statistics, and the World Health Organization for health outcomes.[20] Other key contributors encompass the Uppsala Conflict Data Program for conflict-related deaths, Freedom House for personal freedoms, the International Monetary Fund for fiscal data, and specialized indices like the Environmental Performance Index from Yale and Columbia Universities for biodiversity metrics.[20] Updates to sources incorporate corrections for consistency with prior years, though gaps persist in areas like cyber-crime or gang violence due to insufficient cross-nationally comparable data.[20] Measurement begins with normalization using a distance-to-frontier approach, scaling each indicator to a 0-100 range by comparing country performance against global best- and worst-case benchmarks, with logarithmic transformations applied to 37 skewed distributions (e.g., income inequality) to enhance comparability.[8] Missing values, which affect coverage for some countries and years, are handled through forward- or back-filling where recent data exist, or imputation via linear regressions incorporating productive capacity variables, country groupings, and economic drivers, ensuring no country is excluded from pillar scores.[8] Indicators within elements receive differential weights (0.5, 1, 1.5, or 2) based on their assessed contribution to prosperity, while elements are weighted by fixed percentages summing to 100% per pillar; pillars and domains are equally weighted in aggregation.[2] Final scores result from weighted sums at the element level (yielding 0-100 pillar scores) and unweighted averages across pillars and domains, producing an overall Index score that reflects relative prosperity while maintaining methodological stability across annual iterations.[8]| Pillar Example | Indicator Example | Data Source | Type |
|---|---|---|---|
| Safety & Security | Homicide rate per 100,000 | World Bank | Objective[20] |
| Governance | Judicial independence score | World Justice Project | Subjective[20] |
| Health | Life expectancy at birth | WHO | Objective[20] |
| Natural Environment | CO2 emissions per capita | World Bank | Objective[20] |
Scoring, Weighting, and Aggregation
The Legatum Prosperity Index normalizes its approximately 300 indicators using a distance-to-frontier method, where each indicator's raw value is scaled between the observed worst and best global performances across countries and years.[8] The formula for an indicator's normalized score is (raw value - worst case) / (best case - worst case), yielding a value between 0 and 1, with subsequent transformations such as logarithms applied to 37 indicators to ensure comparability and address skewness.[8] Outliers are trimmed using the 5th and 95th percentiles to prevent distortion from extreme values.[8] Individual indicators receive weights of 0.5, 1, 1.5, or 2—defaulting to 1—determined by expert assessments of their relevance to prosperity outcomes, supported by academic literature and statistical correlations with wellbeing metrics.[2] [8] Within each of the 67 elements (groups of related indicators), element-level weights are assigned as fixed percentages reflecting their proportional contribution to the parent pillar, such as 15% for ocean-related elements in the Natural Environment pillar.[8] The 12 pillars receive equal weighting both within their respective domains and across the index, ensuring no single pillar disproportionately influences the overall score.[2] The three domains—Inclusive Societies, Open Economies, and Empowered People—each comprising four pillars, are also equally weighted in the final aggregation.[2] Aggregation proceeds hierarchically via weighted arithmetic means. An element score out of 100 is calculated as 100 multiplied by the weighted sum of its normalized indicator scores divided by the sum of their weights: E = 100 \times \frac{\sum (w_j \times ind_j)}{\sum w_j}, where w_j is the indicator weight and ind_j its normalized score.[8] Pillar scores out of 100 follow similarly: P = \frac{\sum (\kappa_j \times E_j)}{\sum \kappa_j}, with \kappa_j as element weights.[8] Domain scores are the unweighted arithmetic mean of their four pillar scores, while the overall Prosperity Index score is the arithmetic mean of all 12 pillar scores (equivalent to the mean of the three domain scores given equal domain sizes).[2] [8] Irrelevant indicators or elements—such as land coverage for landlocked countries—are excluded, with remaining weights rescaled proportionally to maintain integrity.[8] This bottom-up approach, stabilized by fixed benchmarks, allows intertemporal comparisons while prioritizing empirical performance gaps over absolute thresholds.[2]Empirical Findings
Recent Rankings (2023 and Later)
The 2023 Legatum Prosperity Index, published by the Prosperity Institute, ranked 167 countries and territories on their overall prosperity, incorporating 104 variables across twelve pillars such as safety, personal freedom, and economic quality.[4] Denmark secured the top position, followed by Sweden in second, Norway third, Finland fourth, and Switzerland fifth.[4] These rankings reflect strong performances in Nordic countries and Switzerland across multiple domains, including governance, health, and living conditions.[4] The United States ranked 19th overall in the 2023 index, with relative strengths in enterprise conditions but challenges in areas like safety and security and social capital.[21] Other notable placements include the United Kingdom at 12th and Japan at 17th, highlighting variations in prosperity drivers beyond traditional GDP metrics.[4] The index's methodology underwent annual review, potentially affecting indicator weights and data sources compared to prior years.[2] As of October 2025, the 2023 edition remains the most recent published, with no 2024 or 2025 rankings released by the Prosperity Institute.[19] This continuity underscores the index's focus on long-term prosperity trends rather than frequent revisions.[6]Historical Trends and Shifts
The Legatum Prosperity Index, first published in 2007, has revealed a pattern of global prosperity gains through 2019, driven primarily by advances in health, education, and living conditions, with under-5 mortality rates declining worldwide from 37 to 26 per 1,000 live births between the early 2010s and 2023, and extreme poverty (below $5.50/day) falling from 57% to 47% of the global population over the past decade.[5] However, aggregate prosperity scores plateaued for the third consecutive year in 2023, following steady improvements from 2015 to 2019, amid weakening economic quality, rising public debt, and institutional divergences.[7] [5] Personal freedoms deteriorated in 108 countries over the 2013–2023 period, linked to democratic backsliding and reduced institutional trust, while social capital strengthened in 127 nations through gains in social tolerance.[5] At the country level, Nordic nations have maintained dominance in top rankings, with Denmark securing first place annually since 2020 due to robust liberal institutions, open markets, and social frameworks.[5] [4] Notable risers include Côte d’Ivoire, the most improved nation from 2013 to 2023, advancing through governance enhancements and economic reforms; Nepal, which climbed significantly with a 56-place gain in social capital; and Kenya, the top improver in 2023 via infrastructure and market access gains.[5] Regional progress in Sub-Saharan Africa elevated average scores from -12.5 in 2013 to -7.4 in 2023, fueled by living conditions and health convergence, though economic growth in the bottom 40 countries slowed from 2.0% to -0.1% annually.[5] Declines have been pronounced in conflict-affected or policy-mismanaged states, with Venezuela dropping 36 places to 145th from 2013 to 2023 due to institutional collapse and economic contraction; Syria falling sharply in the Middle East and North Africa amid civil war, which caused over 300,000 civilian deaths and displaced 37% of its population; and Myanmar deteriorating most in 2023 following political instability.[5] Hong Kong experienced the largest freedom score decline over the decade, dropping to 22nd overall, while the Middle East and North Africa region's scores improved modestly from -13.3 to -5.5, offset by setbacks in Libya and South Africa from weak property rights and investor protections.[5] These shifts underscore a widening gap, where top performers sustain institutional strengths, but lower-ranked countries increasingly lag in governance and economic fundamentals despite gains in basic welfare metrics.[5]| Period | Most Improved Countries (Examples) | Most Deteriorated Countries (Examples) | Key Global Metric Change |
|---|---|---|---|
| 2013–2023 | Côte d’Ivoire (governance rise); Nepal (+56 in social capital) | Venezuela (-36 places); Hong Kong (personal freedom decline) | Personal freedom worsened in 108 countries; social capital improved in 127[5] |
| Recent (2023) | Kenya (infrastructure gains) | Myanmar (political instability) | Prosperity plateau post-2019[7] |
Pillar-Specific Insights
In the Safety and Security pillar, which assesses absence of violence, crime rates, and terrorism, Nordic and Western European nations such as Luxembourg, Switzerland, and Norway consistently rank at the top, benefiting from stable institutions and low conflict incidence. Globally, scores improved over the five years prior to 2023, but Sub-Saharan Africa saw deterioration, with increased terrorism and conflict deaths contributing to lower rankings for countries like Mali, Sudan, and Somalia. The bottom 40 countries experienced a rise in conflict-related deaths from 23,000 to 86,000 over a decade, underscoring persistent security challenges in fragile states.[5][2] The Personal Freedom pillar, evaluating civil liberties, freedom of expression, and tolerance, shows Nordic countries like Norway, Denmark, and Finland leading, with strong protections for assembly and speech. However, global performance deteriorated in 108 countries over the decade to 2023, particularly in the Middle East and North Africa (MENA) and Eastern Europe, due to curbs on assembly and expression; notable declines occurred in Hong Kong (falling to 135th in assembly freedoms) and countries like South Sudan, Yemen, and Egypt at the bottom.[5][22] Governance pillar scores, measuring rule of law, executive constraints, and institutional trust, exhibit a slight global decline over the decade to 2023, with Finland, Norway, and Denmark topping rankings through robust checks and balances. Weak performers include Haiti, the Democratic Republic of Congo (DRC), and Libya, hampered by weak rule of law; Turkey dropped 65 places to 127th amid governance erosion, while Côte d'Ivoire improved 47 ranks via reconciliation efforts.[5] In Social Capital, tracking interpersonal trust, civic participation, and social norms, global improvements occurred through rising tolerance and engagement, led by Denmark, New Zealand, and Norway. Eastern Europe strengthened most notably, but the bottom 40 countries, including Eritrea, Benin, and Central African Republic, lagged in tolerance and participation, highlighting divides in community cohesion.[5][2] The Investment Environment pillar, focusing on property rights and investor protections, saw mixed trends with overall gains; Hong Kong, Finland, and the Netherlands excel due to secure legal frameworks, while Guinea-Bissau, Myanmar, and Central African Republic rank lowest amid instability. Israel stands out at 15th for venture capital access, reflecting innovation-friendly policies.[5] Enterprise Conditions, assessing regulatory ease and business operations, improved via reduced burdens, with Switzerland, Hong Kong, and the United States leading through efficient markets; Egypt surged from 131st to 62nd on reforms, but the bottom 40, including DRC, Cuba, and Yemen, worsened due to heightened regulations.[5] For Infrastructure & Market Access, combining connectivity and trade openness, Singapore, Hong Kong, and the Netherlands top scores with advanced digital and physical networks; Vietnam climbed 19 places to first in market access, while laggards like Sierra Leone, Afghanistan, and Ethiopia face gaps, though Algeria advanced in communications. The bottom 40 diverged, with uneven progress.[5][4] Economic Quality, evaluating growth, employment, and trade integration, favors Singapore, Switzerland, and Hong Kong for resilience and access to 45% of the global economy among top 40 nations; Sub-Saharan Africa's slow growth and debt issues drag down Mozambique, DRC, and South Sudan, with bottom 40 GDP per capita growth turning negative from 2.0% over the decade.[5] The Living Conditions pillar, covering sanitation, housing, and utilities, shows global convergence with sanitation access rising to 78%; Netherlands, Denmark, and Sweden lead, while Papua New Guinea, Somalia, and Niger trail, though Sub-Saharan Africa gained in electricity access despite persistent poverty in MENA from inflation.[5] Health outcomes improved with under-5 mortality dropping to 26 per 1,000 births, converging post-COVID; Singapore, Japan, and South Korea top with high vaccination and access, versus Angola, Guinea, and Liberia; Sub-Saharan Africa reduced maternal mortality but retains disparities.[5] In Education, tertiary enrollment and skills rose globally; Singapore, Finland, and South Korea lead in outcomes, with Kazakhstan up 26 ranks, but Somalia, Liberia, and Mozambique lag; Canada ranks 6th in primary education.[5] The Natural Environment pillar reveals mixed results, with more protected areas but rising emissions; Sweden, Finland, and Latvia excel in preservation, while Iran, Turkmenistan, and Syria rank low; Denmark places 2nd overall, and Mozambique leads Sub-Saharan Africa despite pollution increases in bottom 40.[5]Evaluation and Debates
Empirical Strengths and Validations
The Legatum Prosperity Index exhibits strong convergent validity through high correlations with established measures of economic productivity and subjective wellbeing. Its overall score correlates with productive capacity at R² = 0.83 and with Cantril’s Ladder of life satisfaction at R² = 0.68, explaining substantial variance in these outcomes across countries.[10][8] These associations underscore the index's capacity to capture factors causally linked to wealth generation and personal flourishing, beyond narrow income metrics. Internal reliability is evidenced by Cronbach’s alpha coefficients exceeding 0.7 for most of its 12 pillars and two-thirds of its 67 elements, confirming consistent measurement within domains such as governance (α = 0.95) and education (α = 0.92).[10] Robustness tests further validate stability: alternative equal weighting yields rankings correlating at R² = 0.99 with the standard method, while Monte Carlo simulations produce maximum rank shifts of 12 positions, indicating resilience to weighting variations or data perturbations.[8] The index aligns closely with peer indices, showing correlations above 0.90 with the Human Development Index, Social Progress Index, and Global Competitiveness Index, as well as strong ties (>0.90) to the Sustainable Development Goals Index.[10][23] This convergence supports its empirical credibility in multidimensional assessments, drawing from 300 indicators sourced from reputable entities like the World Bank and WHO, vetted by over 100 global experts. Empirical applications, such as regressions linking index components to wellbeing in contexts like Pakistan (e.g., social aspects coefficient = 0.39), affirm its utility in modeling real-world prosperity drivers.[24] Longitudinal consistency across 16 annual editions since 2007 enables validation through trend analysis, where sustained high scores in pillars like safety and health precede observable improvements in stability and life expectancy, as corroborated by cross-national data patterns.[8] These features position the index as a reliable diagnostic tool for policy, distinguishing it from GDP-focused metrics by integrating causal elements of social capital and institutional quality.Methodological Criticisms
Critics argue that the Legatum Prosperity Index's equal weighting of its pillars and sub-indicators is arbitrary and potentially invalid, as the relative importance of factors like economic quality versus social capital varies across contexts and does not align with empirical correlations among the components. For instance, analysis of the index's sub-indices reveals inconsistent interrelations, suggesting that uniform weights fail to capture causal priorities for prosperity, leading to distorted overall rankings. The aggregation method, which relies on simple averaging of pillar scores to derive a composite index, has been faulted for overlooking country-specific optimal weights, thereby creating an uneven assessment framework that does not account for differing national strengths in various domains. Researchers propose alternatives like data envelopment analysis to allow flexible weighting, arguing that the Legatum approach's rigidity limits its ability to reflect tailored pathways to prosperity and may undervalue specialized performances in areas such as governance or health. The index's heavy dependence on subjective survey data for pillars like personal freedom, governance, and social capital—drawn from sources including Gallup World Poll and World Values Survey—introduces vulnerabilities to cultural biases, response inconsistencies, and perceptual variances that objective metrics avoid.[8] While the methodology combines these with hard data like GDP per capita, detractors note that subjective elements can amplify noise, particularly in diverse global samples where trust or safety perceptions differ systematically by societal norms, potentially skewing rankings for non-Western nations.[25] Data limitations persist, including gaps in coverage for less-developed countries, reliance on imputations or proxies, and outdated inputs for certain indicators, which the Legatum Institute acknowledges but which critics contend undermine cross-country comparability and temporal reliability.[8] Additionally, the index's structure has been accused of embedding a neoliberal bias by prioritizing market-oriented indicators such as business environment and investment freedom, which may favor economies aligned with free-market principles over those emphasizing redistribution or state intervention, though such claims require scrutiny against the index's explicit inclusion of equity and welfare metrics.[26]Comparative Context with Other Indices
The Legatum Prosperity Index (LPI) employs a multidimensional framework assessing 167 countries across 12 pillars, including economic quality, governance, personal freedom, safety, and social capital, using over 300 objective indicators from sources such as the World Bank and national statistics. This contrasts with the United Nations Development Programme's Human Development Index (HDI), which aggregates just four indicators—life expectancy at birth, mean and expected years of schooling, and gross national income per capita—into a geometric mean score focused narrowly on basic capabilities in health, education, and living standards. While the LPI correlates substantially with the HDI (R² = 0.84), it reveals discrepancies where countries like Iran rank higher in HDI due to resource-driven income but plummet in LPI owing to deficits in personal freedom and inclusive societies, highlighting the HDI's omission of non-material prosperity elements.[8] In comparison to economic freedom indices, such as the Heritage Foundation's Index of Economic Freedom, which evaluates 12 factors emphasizing rule of law, government size, regulatory efficiency, and open markets to promote limited intervention and property rights, the LPI's Economy pillar incorporates similar metrics like market openness and employment quality but integrates them within a holistic prosperity model that penalizes weaknesses in health or environment. Analyses indicate that nations classified as "free" in the Heritage index—scoring above 80—consistently outperform in LPI rankings, with 21 of the top 25 prosperous countries per Atlantic Council assessments overlapping with high-freedom economies, underscoring economic liberty's role as a prosperity enabler without reducing outcomes to policy inputs alone.[27] The LPI also diverges from subjective well-being measures like the World Happiness Report, which ranks countries based on self-reported life evaluations from Gallup polls, weighted with GDP per capita, social support, health, freedom, generosity, and corruption perceptions. Unlike the LPI's reliance on verifiable data to track objective outcomes, the Happiness Report prioritizes experiential satisfaction, leading to alignments in Nordic dominance but divergences for resource-rich nations like oil exporters that score lower in LPI's governance and safety pillars despite high incomes. This objective-subjective distinction allows the LPI to emphasize causal drivers of flourishing, such as institutional quality, over transient sentiment.[2]| Index | Key Focus | Primary Indicators | Correlation with LPI (R²) |
|---|---|---|---|
| HDI | Basic human capabilities | 4 (health, education, income) | 0.84[8] |
| Index of Economic Freedom | Market-supportive policies | 12 (rule of law, regulation, trade) | Positive (top free economies lead LPI)[27] |
| World Happiness Report | Subjective life satisfaction | 6 (evaluation, GDP, support, etc.) | Not directly quantified; overlaps in top ranks but methodological divergence |
