Central Bureau of Statistics (CBS) was established in 1959 under Statistics Act as the central agency for the collection, consolidation, processing, analysis, publication and dissemination of statistics. It is under the National Planning Commission Secretariat (NPCS) of Nepal and serves as a national statistical organization of Government of Nepal. It generates timely and reliable socio-economic statistics mainly through the operation of censuses and surveys. The main objective of setting up CBS is to avail data to NPCS and other Government agencies for the formulation of national plans, policies and production of national accounts estimates to measure the economic growth of the country. It carries out different household surveys and censuses regularly to assess the socio-economic condition of the country. The major tasks, which CBS has been performing, are decennial population census, agriculture census and quinquennial manufacturing establishment census.
