Brief history and other relevant background information
Brief history and other relevant background information
Civil Registration Department was established in 1918 to register vital events. Registration of birth, death, marriage and divorce by the Department required the establishment of an organization responsible for collection of information on the country's population. This led to the approval of a regulation in 1924, the department responsible for statistics and its duties was determined and responsibility for collection and centralization of necessary statistics was entrusted to the Ministry of the Interior.
In June 1939, the first census law was approved by National Council Parliament. Based on the law, put into effect from March 1940, the population census was taken only in Tehran, and in 1940 and 1941, 33 cities were gradually enumerated. In March 1952, Cooperation Organization of Public Statistics was established. Statistics and census law was approved in April 1958. In that year, Department of Statistics and Census seceded from the General Department of Statistics and Civil Registration and joined the Cooperation Organization of Public Statistics. Thus, for the first time, an organization, exclusively responsible for collection of statistics, was established and was renamed Department of Public Statistics affiliated to the Ministry of the Interior in 1956.
The Department implemented the first national census of population and housing in 1956. Upon establishment of the Department of Public Statistics, statistical activities entered a new stage and different kinds of surveys were annually executed in different socio-economic areas the most important of which are as follows:
- Agriculture Survey in 1960
- Population Sample Survey in 1963
- Manufacturing Establishments Census in 1963
- Household Budget Survey in 1963

According to the 1965 Law and due to increasing requirements of planning organizations for information and statistics as well as the necessity of very close collaboration of main organization producing statistics with the planning organizations, the Department of Public Statistics was detached from the Ministry of the Interior and transformed into the Statistical Center of Iran (SCI) affiliated to the Plan and Budget Organization.
In 2000, the Plan and Budget Organization and the State Organization for Employment and Administrative Affairs merged together into Management and Planning Organization, to which the SCI is now affiliated. In 2007, Organization of Management and Planning changed to Vice Presidency of Planning and Strategic Supervision At present, Statistical Centre of Iran is depended on Vice Presidency of planning and Strategic Supervision.
