National Statistics Bureau of Bhutan

The National Statistics Bureau (NSB) is the central statistical agency of the Royal Government of Bhutan. It is responsible for compiling and publishing the country's official statistics, including the decadal Population and Housing Census, the Bhutan Living Standards Survey (BLSS), the Statistical Yearbook of Bhutan, the Labour Force Survey and the System of National Accounts. The NSB also serves as Bhutan's representative to the United Nations Statistics Division and to regional statistical bodies such as SAARCSTAT.^[1]

The Bureau is headquartered in Thimphu and is led by a Director who reports to the Cabinet Secretariat. It coordinates a national statistical system that includes line ministry data units, dzongkhag administrations and a network of enumerators trained for periodic surveys. Capacity-building has been supported by the United Nations Population Fund (UNFPA), the World Bank, the Asian Development Bank (ADB) and the Partnership in Statistics for Development in the 21st Century (PARIS21).^[2]

NSB publications are widely used by domestic policymakers, donor agencies and academic researchers. The Bureau is the primary domestic counterpart for international statistical missions and the main source for indicators used in the IMF Article IV consultations and the World Bank's country assessments of Bhutan.

History

A small Statistical Cell was established within the Ministry of Development in 1971 to support the formulation of the country's early Five Year Plans. In 1979 the cell was upgraded into the Central Statistical Organisation (CSO) under the Planning Commission, and the CSO conducted Bhutan's first formal censuses and household surveys through the 1980s and 1990s.^[1]

With major changes in the governance structure in 2003, the CSO was de-linked from the Planning Commission and granted autonomy as the National Statistics Bureau. The NSB operates under an Executive Order issued in 2006, which designates it as the central authority for the collection, compilation and release of official statistics in Bhutan and as the official custodian of national statistical data.^[1] The Bureau's statutory framework has been a recurring subject of policy discussion: successive National Strategies for the Development of Statistics (2009–2013, 2014–2018 and 2024–2029) have identified the absence of a comprehensive statistics act as a constraint on the Bureau's authority and on inter-agency data sharing.^[2]

Population and Housing Census

The Population and Housing Census of Bhutan (PHCB) is the country's principal demographic dataset and the largest single statistical operation undertaken by the NSB. The 2017 census, conducted in May and June across all 20 dzongkhags, recorded a total population of 727,145 — an increase of 16 per cent over the 2005 census — and a population density of 19 persons per square kilometre. The 2017 round was the first to use a fully computer-assisted personal interviewing (CAPI) approach, with enumerators carrying tablets pre-loaded with the questionnaire.^[3]

The next census is planned for 2027, retaining the decadal cycle established by the 2005 and 2017 rounds. Preparatory cartography and pilot enumeration are expected to begin in 2026 under the 13th Five Year Plan.

Major surveys and publications

Bhutan Living Standards Survey (BLSS) — household consumption, income and welfare indicators; conducted in 2003, 2007, 2012, 2017 and 2022. The BLSS is the primary source for poverty headcount estimates and Gini coefficients used by the IMF and World Bank.
Labour Force Survey (LFS) — conducted annually since the 2010s; reports unemployment, youth unemployment and labour force participation rates.
Statistical Yearbook of Bhutan — published annually; the standard reference compilation of macroeconomic, demographic, sectoral and dzongkhag-level indicators.
National Accounts Statistics — annual GDP, sectoral output and expenditure tables; the 2024 edition is the most recent available release.^[4]
Vital Statistics Report — annual; compiled from civil registration and health system records covering births, deaths and marriages.^[5]
Multidimensional Poverty Index — produced jointly with the Oxford Poverty and Human Development Initiative (OPHI), published periodically (most recent 2017, 2022).

Methodology and capacity

The NSB's methodological frameworks track international standards: System of National Accounts 2008 for macroeconomic statistics, ILO Resolution on Statistics of Work for labour data, and UN Principles and Recommendations for Population and Housing Censuses for demographic operations. Capacity constraints — small staff size, limited statistical expertise outside the central Bureau, and uneven data quality from line ministries — have been recurrent themes in donor assessments. The NSB's National Strategy for the Development of Statistics (NSDS) 2024–2029, launched in December 2024, prioritises CAPI rollout across all major surveys, an integrated statistical business register, and stronger inter-agency coordination through a forthcoming statistics act.^[2]

Independent assessments have noted that, although NSB outputs are generally well-regarded, gaps remain in disaggregated data on the Lhotshampa and other ethnic minority populations, and in granular sub-national poverty and labour data. Some sensitive demographic categories are under-reported in published tabulations.

Leadership and structure

The NSB is led by a Director (formally Director General in some periods) supported by deputy directors in charge of the National Accounts Division, the Demographic and Social Statistics Division, the Macroeconomic Statistics Division and the Survey Operations Division. As of 2026, the Bureau employs around 80 staff at its Thimphu head office and maintains liaison statisticians in all 20 dzongkhags. Senior NSB officials regularly serve on inter-ministerial committees including the National Planning Steering Committee and the Macroeconomic Framework Coordination Committee.
