Census in Nepal

The 1911 census was the first official national census in the history of Nepal. It was conducted during the period of Rana Prime Minister Chandra Shumsher. The government issued an official order to the people through Istihar (government notification) to cooperate with the enumerators who were to visit door to door for census enumeration. Patwaris (land revenue collectors) were engaged in data collection all over the country. The census had established a milestone in the tradition of census taking in Nepal. The census recorded total population of 5,638,749.^[3]

The 1920 census was the second census conducted in Nepal. It was aimed primarily to prepare an inventory of slaves (Servant, Bandha and Kariya, Kamara-Kamari). Another purpose was to count the number of taxable people as well as young people available to be recruited in the security forces.^[3]

The third census was conducted in 1930 under Prime Minister Bhim Shumsher, during a time of war rhetoric and preparation between Nepal and Tibet. The population count was therefore thought to be grossly undercounted because of the fear of compulsory recruitment in the army.^[3]

The census of 1941−42 was the fourth census of Nepal. It was the first census conducted by a permanent statistical office named Janasankhya Goswara (Department of Population), during the period of Prime Minister Juddha Shumsher. The department had attempted to improve census coverage by improving the schedule, by recruiting more enumerators and also by reducing the census areas.^[3]

This was the fifth census and first modern census conducted in Nepal. It was conducted after the advent of democracy in 1951. The census was conducted in two phases: the Eastern part of the country except Mahottari District was enumerated in 1952 whereas the Western part and Mahottari District were enumerated in 1954.^[3]

This was the sixth census conducted in Nepal. It was the first census conducted by Central Bureau of Statistics, established in 1958.^[3]

This was the seventh census conducted in Nepal. It was the first census conducted after the division of Nepal into 14 zones and 75 districts in 1962. It was also the first census to use computer for data processing.^[3]

This was the eighth census conducted in Nepal.^[3]

This was the ninth census conducted in Nepal.^[4] This was the first census to formally collect and publish data on caste and ethnicity.^[3]

This was the tenth census conducted in Nepal. Census enumeration was affected in different parts of the country due to then-ongoing Maoist insurgency.^[5][6]

This was the eleventh census conducted in Nepal.^[7] It marked the 100 years of census taking in Nepal.^[3]

This is the twelfth census conducted in Nepal. It is the first census conducted under the new federal structure of 7 provinces, 77 districts and 753 local bodies.^[8]
