The first Household Socio-Economic Survey was conducted by the National Statistical Office (NSO) in 1957, known as " The Household Expenditure Survey". This name was changed to the Household Socio-Economic Survey in 1968 - 1969 and the survey was conducted every five years. Due to the rapid economic expansion and the importance of the survey in order to set the anti-poverty policy, the Ministerial Cabinet had passed an approval on September 8, 1987 for the NSO to carry out the survey every two years. The 2000 survey is the fifteenth survey of this kind. (The 1999 was conducted special periodic survey by the cabinet assignment.)
