Data and metadata are transmitted to Eurostat by the Member States in the framework of the Unified Demographic Data Collection which is in accordance with Regulation (EC) No 862/2007 and Regulation (EU) No 1260/2013 and their implementing regulations. This Euro SDMX Metadata Structure is used for the purpose of quality reporting. The definition of the quality concepts and guidelines are described in the European Statistical System Handbook for Quality Reports. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
3.2. Classification system | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
The regional breakdown of the Member States in the regional demographic tables is done under the most recent NUTS classification. There are agreements between Eurostat and Candidate countries as well as between Eurostat and EFTA countries, for which statistical regions have been coded in a way that resembles NUTS. For more information on the versions in force, please see: https://ec.europa.eu/eurostat/web/nuts/. The Nomenclature of Territorial Units for Statistics (NUTS): It was defined in order to collect regional statistics, to analize the socio-economic structures of regions, to set the frame of regional politics and to constitute the comparable statistical database which is convenient to the EU Regional Statistical System. In this system, provinces are defined as “Level 3”; closer provinces which are similar by their economic, social and geographic structures are grouped in hierarchy as “Level 1” and “Level 2” by considering their regional plans and population size.
International Standard Classification of Education (ISCED): ISCED is designed to serve as an instrument suitable for assembling, compiling and presenting comparable indicators and statistics of education both within individual countries and internationally. It presents standard concepts, definitions and classifications. ISCED covers all organized and sustained learning opportunities for children, youth and adults including those with special needs education, irrespective of the institution or entity providing them or the form in which they are delivered. In international migration statistics, TurkStat Classification Server and country list of the Ministry of Foreign Affairs are used for country names. |

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 10 November 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. 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 establish the Address Based Population Registration System (ABPRS) in 2007. The aim of this study was to develop existing administrative records based on addresses. Population Services Law No. 5490 dated 25 April 2006 was the legal base for the ABPRS. One of the purposes of the ABPRS were 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 Türkiye, to match the address information and the Central Civil Registration System-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 of 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-3 level since 2009. |
|||
6.2. Institutional Mandate - data sharing | |||
According to the Turkish Statistical Law with Article 12, access to statistical results are given as follows: Article 12 - 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. The statistical information compiled by the TurkStat cannot be given to any person or authority before this information is made open to public. *Programme: The Official Statistics Programme Population Population Services Law No. 5490 charged TurkStat for establishing the ABPRS, and Ministry of Interior, the General Directorate of Civil Registration and Citizenship (GDCRC) of the Ministry of Interior for developing and maintaining the system. Changes in usual residence addresses are entered to the system by the Provincial and District Directorates of Population of the GDCRC. Updated information on population size and the basic characteristics of population is obtained from the system and announced by the TurkStat.Governmental organizations and establishments access the registers in the system for their administrative works by a protocol with GDCRC according to the Law. International Migration Statistics Annual immigration and emigration flow statistics were calculated based on Address Based Registration System, where the records of Turkish Republic (T.R.) citizens and foreigners residing in Türkiye are kept, and the database on T.R. citizens living abroad. Both these two systems are updated by the Ministry of Interior General Directorate of Civil Registration and Citizenship (GDCRC). The main data sources are ABPRS, records of Turkish Republic citizens living abroad, residence permits, work permits, Central Civil Registration System (MERNIS) records dated 31 December, and birth/death records. |

13.1. Accuracy - overall | ||||||||||||||||||||||||||
For both migration stocks and flows, some foreigners have unknown citizenship. Although it is known that these persons are foreign citizens, their country of citizenship is unknown. Likewise, but much more than the country of citizenship, the data includes nationals and non-nationals with unknown place of birth. In the births particularly information about foreign mothers taken from Central Civil Registration System and in the marriages and divorces information of the foreign partner taken from Central Civil Registration System are lack. Also, other information of foreign persons added to main birth and main death data are in line with the criteria used for determination of foreign population in the ABPRS. For deaths which covered in the Central Civil Registration System, but not covered in Death Notification System (yet or will never be transferred to the TurkStat) are published as ‘Unknown’, but not ill-defined, in terms of causes of death. The coverage and timeliness of civil registration is more comprehensive than MoH. That’s why there are records (given “unknown”) in the statistics (comes from civil registration) as a deceased person which they cannot be assigned an underlying cause of death since it’s not included in the Death Notification System (MoH). |

18.1. Source data | ||||||||||||||||||||||||||||
Address Based Population Registration System (ABPRS) In order to obtain up-to-date information on population size of localities and monitoring the population movements, ABPRS was established in 2007 by the Turkish Statistical Institute and subsequently transferred to the General Directorate of Civil Registration and Citizenship (GDCRC) which is the responsible institution for maintaining and updating the system. The legal base of ABPSRS is the Population Registration Law No. 5490. In the establishment process of the system, addresses of the Turkish citizens and foreigners residing in Türkiye, of which were identified in the National Address Database (NAD), were obtained and this information were matched, for Turkish citizens, with the registers of the MERNIS database by using the Turkish Republic identification numbers. For foreign citizens, usual residence addresses were matched by using passport numbers. Annual information on population size and basic characteristics (i.e. age and sex structure, legal marital status, province of civil registration, internal migration, place of birth, foreign population, household size and type) of the population are produced by localities. For foreign citizens, usual residence addresses were matched by using passport numbers. ABPRS is also used as a base for population projections, life tables and international migration statistics. National Address Database (NAD) Database that covers all address components within the borders of the country. Numbering study, which was the source for the NAD, was carried out by municipalities in localities having municipal organizations, and by special provincial administrations in villages. Later on, by entering address information to the system via a web-based program developed by the Turkish Statistical Institute, NAD was established in 2006 and subsequently transferred to the GDCRC. Municipalities are obliged to enter the address changes into the system regularly, and to give construction and occupancy permits through this system by using the database. Administrative attachment, name and legal entity changes of provinces, districts, towns, villages and quarters (including small areas connected some villages) are reflected to the NAD by the GDCRC. In the NAD, name and/or number of square, avenue, main street, street, building and dwelling (dwelling unit, office, etc.) are updated by municipalities and special provincial administrations. On the other hand, changes in usual residence addresses of persons are entered in the system by the local population registration offices according to the declarations of the persons. Updated information from the ABPRS and other administrative registers is published annually by the TurkStat. The Central Civil Registration System (MERNIS) It is a database within the Ministry of Interior, General Directorate of Civil Registration and Citizenship (GDCRC) which includes population registers in the form of family ledgers. Birth, death, marriage and divorce events, citizenship and other vital events are registered by local population directorates of the GDCRC. Population registers are kept in the form of family ledgers which is arranged according to the father for each family.

Population Statistics: Address Based Population Registration System (ABPRS) was established in 2007 by the Turkish Statistical Institute and subsequently transferred to the General Directorate of Civil Registration and Citizanship (GDCRC) which is the responsible institution for maintaining and updating the system. 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. Annual ABPRS results by the end of the year (31 December) have been announced to the public in February with a press release. International Migration Statistics: International migration statistics are produced based on ABPRS annually beginning from 2016. The main data sources are ABPRS, records of Turkish Republic citizens living abroad, residence permits, work permits, Central Population Administration System (MERNIS) records dated 31 December. Vital Statistics: Vital statistics are also produced from this system annually. |

18.3. Data collection | ||||||||||||||||||||||||||||
National Address Database (NAD): It covers all addresses within the boundaries of the country. Numbering studies, which were the source for the NAD, were carried out by municipalities in localities having municipal organizations, and by special provincial administrations in villages. After infrastructural studies of the NAD were implemented by the TurkStat, the database was established in 2006. Addresses on the NAD are controlled and problems related with addresses which are wrong or not found in the field or are not present in the NAD are solved and corrections are done on the database. In this manner, the NAD and addresses in the field are compatible. While addresses in the NAD are updated by municipalities, changes in administrative units are updated by General Directorate of Civil Registration and Citizenship (GDCRC). Address Based Population Registration System (ABPRS): ABPRS was established in 2007 by the Turkish Statistical Institute and subsequently transferred to the General Directorate of Civil Registration and Citizenship (GDCRC), which is responsible for maintaining and updating the system. In the establishment process of the system, addresses of the Turkish citizens and foreigners residing in Türkiye, of which were identified in the National Address Database (NAD), were obtained and this information were matched, for Turkish citizens, with the registers of the MERNIS database by using the Turkish Republic identification numbers. For foreign citizens, usual residence addresses were matched by using passport numbers. Address Based Population Registration System is updated by the following three ways:
The Central Civil Registration System (MERNIS): It is a database within the Ministry of Interior, General Directorate of Civil Registration and Citizenship (GDCRC) which includes population registers in the form of family ledgers. Birth, death, marriage and divorce events, citizenship and other vital events are registered by local population directorates of the GDCRC. Population registers are kept in the form of family ledgers which is arranged according to the father for each family. Causes of death data: Death certificate is filled out by the physicians in the hospitals, family health centers, institutions of municipal medicine, institutions of forensic medicine and other health institutions via Death Notification System (DNS). Coding the diseases at the sections for the determination of causes of death are done according to International Classification of Diseases (ICD-10) and underlining causes of death are determined in TurkStat Regional Offices. Residence/work permits: In terms of international migration, records of residence permits are kept by Ministry of Interior Presidency of Migration Management and records of work permits are kept by Directorate General of International Labour Force. Records of foreigners and Turkish Republic citizens living abroad: Records of foreigners and Turkish Republic citizens living abroad are kept and maintained by GDCRC. These records are transferred to Turkstat simultaneously. |
