GNH Survey Methodology and Limitations

The GNH Survey Methodology refers to the technical framework through which Bhutan measures Gross National Happiness, its alternative development index. The survey is administered every five years by the Centre for Bhutan and GNH Studies (CBS), using the Alkire-Foster multidimensional measurement method developed in collaboration with Oxford University's Oxford Poverty and Human Development Initiative (OPHI). While the methodology has been praised for its ambition and multidimensional approach, it has also attracted significant criticism regarding its coverage, sample design, subjective thresholds, and the gap between its findings and other international wellbeing measures.

Structure of the GNH Index

The GNH Index is built around nine domains, each weighted equally:^[1]

Domain	Indicators
Psychological Wellbeing	Life satisfaction, emotional balance, spirituality
Health	Self-reported health, disability, mental health
Education	Literacy, schooling years, knowledge, values
Time Use	Working hours, sleeping hours
Cultural Diversity and Resilience	Language, artisan skills, cultural participation
Good Governance	Government performance, rights, services
Community Vitality	Social support, community relationships, family
Ecological Diversity and Resilience	Environmental quality, ecological issues, responsibility
Living Standards	Income, assets, housing

These 9 domains are disaggregated into 33 indicators, which are further broken into 124 variables. Survey respondents answer approximately 300 questions. The survey was originally designed to take about 9 hours per respondent; this was subsequently condensed to approximately 3 hours.^[2]

The Alkire-Foster Method

The GNH Index employs the Alkire-Foster (AF) method, developed by Sabina Alkire and James Foster at Oxford, which was originally designed for multidimensional poverty measurement. The method identifies who is "happy" by examining sufficiency across multiple dimensions simultaneously, rather than relying on a single summary measure.

A "sufficiency" threshold is set for each indicator. A person is classified as "happy" if they achieve sufficiency in at least 66% of the 33 weighted indicators. The overall GNH Index is then calculated as 1 minus the adjusted headcount ratio (the proportion of the population that is "not yet happy," weighted by the breadth of their insufficiency). The 2022 survey reported an index value of 0.781, up from 0.743 in 2010.^[3]

Survey Results Over Time

Three national GNH surveys have been conducted: in 2010, 2015, and 2022. The 2022 survey classified the population as follows:^[4]

The classification system has itself been a subject of debate. The label "narrowly happy" describes people who have achieved sufficiency in between half and two-thirds of the indicators — a group that could equally be described as "broadly insufficient." The 2022 finding that a majority of Bhutanese (51.9%) did not meet the happiness threshold, while factually reported by the CBS, is rarely emphasized in international media coverage of GNH.

Methodological Criticisms

Sample Size and Representation

The survey samples approximately 8,000 households from a population of roughly 780,000. While the sample is designed to be nationally representative and stratified by district, gender, age, and urban-rural residence, the sample represents roughly 1% of the population. Critics have questioned whether this is sufficient to capture the diversity of experiences across Bhutan's varied geography and demographics, particularly in remote rural areas where access is difficult.

The OECD has noted that while the overall GNH Index was computed from survey data, it was "not considered valid for any statistical analysis" at the district level in earlier rounds due to limited sample sizes, reducing its usefulness as a tool for targeted policy intervention.^[5]

Population Exclusions

The most significant coverage limitation is that the GNH survey is administered only to Bhutanese citizens. This excludes:

• The over 100,000 Lhotshampa expelled from Bhutan in the 1990s and their descendants, now living in the United States, Australia, Canada, Nepal, and other countries
• The approximately 6,500 Lhotshampa remaining in refugee camps in Nepal
• Non-citizen residents classified as "non-nationals" by the Bhutanese government — a 2005 census found 13% of the resident population fell into this category
• Indian and other migrant workers in Bhutan, who form a significant portion of the construction and service labor force

By excluding expelled and marginalized populations, the survey measures the happiness of a self-selected citizenry — those who were permitted to remain and those whose citizenship was not revoked. Critics describe this as measuring satisfaction among a group pre-filtered for belonging.

Subjective Thresholds

The 66% sufficiency cutoff that determines who is "happy" is a normative choice, not an empirically derived boundary. Different threshold choices would produce substantially different results. Meier and Chakrabarti noted that the GNH Index is "highly subjective, reflecting habituation to persistent deprivations" — meaning that people who have never experienced certain freedoms or conditions may report satisfaction with their absence.^[6]

Cross-Country Comparability

The GNH Index is not designed for international comparison. It measures sufficiency within Bhutan's own framework, using Bhutan-specific thresholds and culturally situated indicators. This means the common public understanding that Bhutan is "the happiest country in the world" is not supported by the GNH methodology itself — it is a media construction. Bhutan's own index has never claimed this; it is a domestic policy tool, not a ranking system.

Discrepancy with the World Happiness Report

The gap between Bhutan's GNH claims and its ranking on the UN World Happiness Report (WHR) illustrates a fundamental measurement difference. On the WHR, which uses the Gallup World Poll's "Cantril ladder" question asking respondents to rate their lives on a 0-10 scale, Bhutan has ranked around 95th out of 156 countries. In the 2018 report, Bhutan's ranking fell from 84th (2013-2015 data) to 97th (2015-2017 data).^[7]

Bhutan has been excluded from some editions of the WHR due to incomplete Gallup polling data. Naffis-Sahely noted that "Bhutan provides incomplete happiness data to the UN's World Happiness Report — the very mechanism it inspired — undermining transparency claims."^[8]

Proponents of GNH argue that the WHR's methodology is itself limited — overly weighted toward GDP per capita, social support, and life expectancy metrics that favor wealthy nations. However, the discrepancy between Bhutan's carefully cultivated reputation as the world's happiest country and its middling performance on the one survey that actually compares countries remains a significant point of criticism.

Comparison with Other Wellbeing Indices

The GNH Index is one of several alternative measures of progress developed since the 2000s. The OECD Better Life Index (launched 2011) covers 11 dimensions across 40+ countries. The Human Development Index (HDI), published by the UNDP since 1990, measures health, education, and standard of living. The Social Progress Index measures basic human needs, foundations of wellbeing, and opportunity across 169 countries.

Unlike these indices, GNH is not designed for cross-national comparison and is administered by the government being measured — a potential conflict of interest that distinguishes it from independently administered surveys. The Gallup World Poll, by contrast, is conducted by an independent organization using consistent methodology across countries.

The Scalability Question

Several observers have questioned whether the GNH model could be applied in larger, more diverse countries. The survey requires trained enumerators to spend hours with each respondent, and the national survey takes approximately nine months to complete in a country of fewer than 800,000 people. The culturally specific nature of many indicators — including those related to Buddhist practice, traditional knowledge, and Bhutanese customs — limits transferability. While GNH has influenced wellbeing measurement globally, no other country has adopted Bhutan's specific methodology at national scale.
