3.1. Data description | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
POPULATION Indicators related to the population are based on Address Based Population Registration System (ABPRS). All Turkish citizens and foreigners residing in Turkey are covered in the ABPRS. Legal residence population (de-jure) definition is used. Foreign population covers individuals:
In addition to Syrians under temporary protection, foreigners holding visas or residence permits shorter than 3 months with the purpose of training, tourism, scientific research, etc. are not covered in the ABPRS. Population statistics are produced from this system annually since 2008 with the reference date December 31.
INTERNATIONAL MIGRATION (Immigration and Emigration) Turkish Statistical Institute (TurkStat) produced information on immigration and emigration, namely annual migration flow statistics, for the first time based on administrative registers in 2018. Immigration and emigration statistics for the reference year 2022 will be announced via press release on 24 July 2023. Annual migration flow statistics are calculated based on Address Based Population Registration System, where the records of Turkish Republic (T.R.) citizens and foreigners residing in Turkey are kept, and the database on T.R. citizens living abroad. Both these two systems are updated by the General Directorate of Civil Registration and Citizenship Affairs (GDCRC) affiliated to the Ministry of Interior. International migration statistics are being produced annually starting from 2016 based on consecutive two ABPRS dated December 31. Immigration and emigration statistics are calculated in line with the criteria used for determination of foreign population in ABPRS. Immigration covers Turkish Republic (T.R.) citizens and foreigners who are present in the reference year ABPRS but not in the previous year ABPRS. Emigration covers Turkish Republic citizens and foreigners who are not present in the reference year ABPRS while present in the previous year ABPRS.
VITAL STATISTICS Vital events including births, deaths, marriages and divorces are obtained from the central civil registration system-MERNIS database, which is kept and updated by the General Directorate of Civil Registration and Citizenship Affairs (GDCRC) affiliated to the Ministry of Interior, and statistics are produced. Vital events including births, deaths, marriages and divorces are obtained from the central civil registration system-MERNIS database, which are kept and updated by the General Directorate of Civil Registration and Citizenship Affairs (GDCRC) affiliated to the Ministry of Interior, and produced statistics.

6.1. Institutional Mandate - legal acts and other agreements | |||
Turkish Statistical Institute The compilation and dissemination of the data are governed by the Turkish Statistical Law No. 5429 of November 10, 2005. The purpose of this law is to determine basic principles and standards concerning the production and organisation of official statistics; and to regulate the formation, duties, and authorities of the Turkish Statistical Institute (TurkStat) which is to compile and assess data and information, produce, publish, and disseminate statistics on the areas that country needs, and to ensure coordination among institutions and organizations that are involved in the statistics process prescribed in the Official Statistics Programme (Article 1). The Official Statistics Programme establishes the framework for official statistics that shall 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 analysis, the Programme covers statistics needed to determine and monitor the situations of the country in the fields of economy, social issues, demography, culture, environment, science, technology and any other required areas (Article 3). The Presidency, institutions and organisations taken part in the Programme shall take the measures to ensure the easy and equal access to the official statistics by all users by obeying the standards and release calendar specified in the Programme. Population Data on population and housing are compiled according to the responsibilities stated in Paragraph (a) of Article 29 of the Turkish Statistical Law on collecting the required statistical information on population, housing, education, culture, tourism, health, sports, justice, media, politics and other social subjects, analyzing them and calculating related indicators. TurkStat carried out the field application in order to develop the ABPRS. The aim of this study was to develop existing administrative records based on addresses. Population Services Law No. 5490 dated April 25, 2006 is the legal base for the ABPRS. Purposes of establishing the ABPRS are to establish National Address Database (NAD) that covers all addresses within the boundaries of the country, to obtain the address information of Turkish citizens and foreigners living in Turkey, to match the address information and the population registers (MERNIS) by using the Turkish Republic identification numbers for Turkish citizens, to match the address information and passport numbers of foreigners and to keep this information in a separate database. Vital Statistics Vital events including births, deaths, marriages and divorces are obtained from the central civil registration system-MERNIS database, which is kept and updated by the General Directorate of Civil Registration and Citizenship Affairs (GDCRC) affiliated to the Ministry of Interior, statistics are produced. MERNIS was converted to the online system in 2001. After that, birth statistics has been produced since 2001 from population registers. While birth statistics has been published according to the place of event (the place of birth occurred) in 2001-2008, it has been published according to the usual residence after 2009. Death statistics has been produced from MERNIS database since 2009. Death data taken from MERNIS database are matched with the causes of death data of TurkStat. So, death events not included in MERNIS database are added to the statistics. Main fertility and mortality indicators have been produced by NUTS-III level since 2009. |

Population Statistics: Address Based Population Registration System (ABPRS) was established based on existing administrative registers. Changes in usual residence addresses are entered to the system by the Provincial and District Directorates of the GDCRC. ABPRS is updated by the following three ways:
Updated information on population by localities and the basic characteristics of population are obtained from the system annually by the TurkStat. ABPRS results by the end of the year (December 31st) have been announced to the public in January/February with a press release. Vital Statistics: Vital statistics are also produced from The Central Civil Registration System (MERNIS) annually. International Migration Statistics: International migration statistics are produced annually based on ABPRS. Annual migration flow statistics are calculated based on ABPRS, where the records of Turkish Republic (T.R.) citizens and foreigners residing in Turkey are kept, and the database on T.R. citizens living abroad. Both these two systems are updated by the General Directorate of Civil Registration and Citizenship Affairs (GDCRC) affiliated to the Ministry of Interior. In addition to the ABPRS and records of Turkish Republic citizens living abroad, residence permits, work permits, MERNIS records dated 31 December, and birth/death records are used. |
