Multi-annual or annual work program
The Official Statistics Programme provides the framework for official statistics that will be produced on subjects required at national and international level. Censuses and surveys are carried out within the framework of this Programme.

Taking into account the existing resources, the burden on the respondents and the cost-benefit relation, the Programme covers statistics needed to determine and monitor the status of the country in the fields of economy, social issues, demography, culture, environment, science, technology, etc.

The Programme is drafted by the Turkish Statistical Institute for a term of five years in line with the advisory comments of the Statistics Council and presented to the Council of Ministers. The Programme is put into practice upon the publication of the related decision of the Council of Ministers in the Official Gazette. When needed, amendments to the Programme may be introduced, again by soliciting the opinion of the related organisations, upon the proposal of the TURKSTAT and decision of the Council of Ministers and will be published in the Official Gazette. The TURKSTAT is in charge of implementing the Programme.

In relation to the implementation of the Programme, the TURKSTAT prepares annual monitoring reports to be submitted to the Statistics Council and informs the public with appropriate media.
Main duties
The Turkish Statistical Institute is a technical and scientific institute which produces publications to fulfill Turkey's information needs on social, economic, and cultural subjects. The main function of TURKSTAT is to comprehensively determine information needs, collect and compile data, and finally, to present information to its users according to the highest international standards.

Brief history and other relevant background information
Brief history and other relevant background information
Collecting statistics has a considerably long past in Turkish history. Historical documents show that the Seljuks and the Ilhanids collected information regarding population. Statistical studies began in the early years of the Ottoman Empire. Special importance was given to collecting information on agriculture and land. For this purpose, between the years of 1326-1360 and 1360-1389, several land population censuses were carried out. Later, between 1512-1520, Sultan Selim initiated a general census and had it written into the constitution that it should be repeated every 100 years. The first population census completed during the era of the Ottoman Empire was taken in 1831, during the time of Mahmut II.

From the beginning of the 19th century statistical offices were opened with a centralized system in every ministry in Istanbul and in every province and district. Additionally, a committee was formed to control and follow their studies. All statistical duties and services were brought into legal status by the formation of a central statistical council at Bab-i Ali (the Central Office of the Imperial Government). In 1918, a statistical department was established through a new law, and separate statistical activities were combined within the same office. A year later, however, with the cancellation of that law, the old system was maintained until the period of the Turkish Republic.

The foundation of the present statistical services began with the establishment of "The Central Statistical Department" in 1926 after the founding of the Republic and functioned as partially centralized system. In 1930, the title of the department was changed to "The General Directorate of Statistics", and "The National Statistical System" became centralized. Between the years 1926-1960, this directorate conducted 11 censuses and surveys; we publish many titles on economic, social and cultural subjects.

Due to the need for improvements in the statistical system of the country, Law No:53 was enacted in June 1962 to set up the State Institute of Statistics under the Office of the Prime Minister. In democratic forms of government, information systems facilitate the transmission of verifiable information. It is this characteristic of widely accessible in formation that allows states to integrate into the world system and function effectively. Because of the almost universal recognition of the importance of statistics and the subsequent demand for them, the State Institute of Statistics (SIS) and its functions were further reorganized and rearranged by legal decrees no.219 and no.357 in 1984 and 1989 respectively, taking into consideration Turkey's newly emerging needs and circumstances.

In the context of compliance to European Union requirements, a new Statistics Law was enacted in November 2005, and the name of the State Institute of Statistics has been changed to “Turkish Statistical Institute” (TURKSTAT). This new law increased the coordinating role of the Turkish Statistical Institute within the Turkish Statistical System, and strengthened the coordination power of TURKSTAT.

Other producers of official statistics
Other producers of official statistics
Examples of data compiled by other institutions are: data on the banking sector by the Central Bank, data on government budget and debt by the Undersecretary of Treasury and State Planning Organization.

Official statistics are produced, disseminated and published by the Turkish Statistical Institute and institutions and organisations specified in the Official Statistics Programme. The programme clearly defines the duty realms of these institutions and organisations together with their duties and authorities in the compilation, evaluation and publication of data relating to official statistics in their respective areas. Such institutions and organisations are obliged to submit to the TURKSTAT any compiled data on time upon request. The principle of confidentially including those specified by other legislative arrangements is duly observed in the maintenance and protection of data and information submitted. The TURKSTAT is authorised to publish and disseminate official statistics compiled by institutions and organisations.

Work conducted by institutions and organisations in statistical areas not covered by the Programme and outcomes of censuses or surveys administered by real persons and legal entities under special law are not considered as official statistics.

Real persons or legal entities under special law who conduct surveys entailing statistical outcomes are obliged, in case they make their findings public through the media, to inform the public also about the coverage, sampling method used, sampling volume, data compilation methods and time of the survey concerned.
