Definiton of data: Death certificate which 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) include information on causes of death  which coding process of the diseases at the sections for the determination of causes of death are done according to International Classification of Diseases (ICD-10) and underlying causes of death are determined in TurkStat Regional Offices. 

COD data are derived from death certificates. The medical certification of death is an obligation in Türkiye. The information provided in the medical certificate of cause of death into ICD codes according to the rules specified in the ICD. Data on causes of death (CoD) provide information on mortality patterns and form a major element of public health information. CoD data refer to the underlying cause which - according to the World Health Organisation (WHO) - is "the disease or injury which initiated the train of morbid events leading directly to death, or the circumstances of the accident or violence which produced the fatal injury".

Since 2020 (2019 ref. year) COD data are eventually linked and combined with death registers which are mainly derived from Central Civil Regisration System (MERNİS) and are broken down by sex, 5-year age groups, cause of death and by residential province of deceased person. For stillbirths and neonatal deaths additional breakdowns might include age of mother, which the data are derived directly from Minidtry of Health (MoH), Death Notification System (DNS), as done in the past, previously.

Since 2020, death and causes of death statistics have began to be disseminated in a single press release and kept together in one table. Annual national data are provided in absolute number which is equal with death statistics.

Coverage of deaths which is published according to civil registration uses also MoH data as a secondary source, but stillbirths came only from MoH data. So while GEN file was created according to the published data in the frame of death statistics, SBN file was created from MoH data just using the same roadmap/codes as previous years. Since 2020, the coverage has been changed for deaths but this is not possible for those stillbirths.

SBN file has been driven from the Death Notification System and GEN file from MERNIS (Central Civil Registration System). So, the former includes only cases occurred in Türkiye with also residents abroad, while the latter includes only residents of Türkiye with also cases occurred abroad until 2021. Since, the sources and their coverage are different, infants are not consistent in the two files which the discrepancies are not errors and are due to the different sources. Since reference year 2022 non-residents derived from Death Notification System has been included in the aggreagated GEN file with residents of Türkiye. 

Adding a break in series flag to 2018 is appropriate because of changing coverage. Actually, it's taken (join by a unique ID) the ICD codes from MoH (Death Notification System), all other information are taken from civil registration (MERNIS) for deaths (not stillbirths). The coverage of civil registration is more comprehensive than MoH, since the deaths in the areas have been notified quickly in civil registration system by kin of the deceased but later in MoH where a physician was absent in such places. That’s why there are records (given “unknown-R99”)  in the statistics (comes from civil registration) as a deceased person which an underlying cause of death cannot be assigned since it’s not included in the Death Notification System  (MoH). Technically, it’s not possible to give different codes to the same record.

In 2025 (Reference Year 2023), the consistency between the GEN and SBN files have been provided by harmonizing neonatal deaths (0-27 days) part of SBN data deriven from Death Notification System with the same group of GEN (published mortality) data deriven from Central Civil Registration System. 

25 December 2025

Concepts and definitions are described in the Commission regulation (EU) No 328/2011 in articles 2 and 3.

Cause of death: These statistics are based on underlying causes of death.

Coding the diseases at the sections for the determination of causes of death are done according to International Classification of Diseases (ICD-10) and underlying causes of death are determined according to same classification. Then, data are disseminated by grouping. 

"O00-O99" code known as "Complications of pregnancy, childbirth and puerperium" covers following categories: "Death occured at the pregnancy period", "Death occured at the childbirth process", "Death occured within 42 days after the birth" and also "Death occured between 42 days and 365 days after the birth".

The statistical units are the deceased persons and the stillborns, respectively.

The statistical unit is the deceased person. The reporting unit is the certifier. This is in most cases a physician. In the case of non-natural deaths, the certification could be made by forensic physicians.

Deaths occured in Türkiye and which their death certificates have been filled out by physicians are covered who were residing in Türkiye in the reference year.

Mid-year population (of residents) which are estimated from Address Based Population Registration System (ABPRS).

In national population which is called Address Based Population Registration System (ABPRS) and in national vital statistics, Turkish Republic citizens and foreign nationals residing within the boundaries of the country are covered.

Foreign population covers individuals who are holding a valid residence/work permit at the reference day and individuals who have a valid address declaration at the reference day while holding an identity document equivalent to residence permit such as international protection identity document and the individuals who have already renounced his/her Turkish Republic citizenship and who have a valid address declaration at the reference day. 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.

Before 2008 and previous It was used the International Classification of Disease (ICD-8) containing 50 and 150 diseases as required by the World Health Organization which only covered province and district centers. Since 2009 geographical coverage is Whole Türkiye, while data of 2009-2017 years covers deaths occured in Türkiye and their death certificates are filled out by physicians published by residing provinces, data since 2018 covered deaths who residing in Türkiye before dying in a certain year published by Statistical Regions Classification.

For the main source (Death Notification System) on causes of death; All death events occured in Türkiye are included in the national database except for death events not certified by physicians.

For the national death and causes of death statistics published since 2018; usual residents of Whole country including foreigners are covered. 

Causes of death data;

From 2018 onwards, are available for the province and districts according to the usual residence of deceased person.

Geographical coverage: Between 2009 and 2017 deaths occured in Türkiye and their death certificates are filled out by physicians are covered while 2018 onwards deaths are covered who residing in Türkiye before dying in a certain year.

Data are available at national level and NUTS 1-2-3 level.

Deaths transferred from the Ministry of Health (MoH) Death Notification System (DNS) within the reference year (between January 1 and December 31) are covered, and in order to capture the scope, deaths from the previous year transferred within the first 3 months (January, February, March) following the reference year are also included in the publication period. In addition, cause of death data were revised 1 year retrospectively due to delayed registrations originated from judicial process etc. to the administrative records and registers added/updated later for the revised ones are also included in the publication period. The 2024 press release has been published including 2024 reference year and revised 2023 reference year in CoD Statistics.

Death events of foreigners are included. They are included in line with the criteria used for determination of foreign population in Address Based Population Registration System (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).

Causes of Death data are checked with administrative data sources such as Address Based Population Registration System (ABPRS), Ministry of Health (MoH) Death Notification System and Birth Notification System (for infant deaths which has not been registered in death records yet) and Central Civil Registration System (MERNIS).   

Death events of foreigners in the Death Notification System (DNS) are included in the statistics in line with the criteria used for determination of foreign population in Address Based Population Registration System (ABPRS).

Cause of death statistics have been compiled and coded in accordance with International Classification of Diseases (ICD-10) of the World Health Organization (WHO). The "Death Notification Form". For accuracy and checks in this regard, ACME (Automatic Classification of Medical Entry) documents in accordance with international methodology are used.

The data are published in absolute numbers which is collected at individual level. 

Diagnoses are coded according to ICD 10 and underlying causes are found by means of ACME decision tables and rules.

Ministry of Health (MoH), Death Notification System (DNS); Medical and non-medical information of deceased person are collected.

Causes of death data are collected from; Hospitals, family health centers, institutions of municipal medicine, institutions of forensic medicine and other health institutions. 

The collected data is transferred to TurkStat through the Ministry of Health Death Notification System.

Annual.

Year Number of months between the end of the reference year and the publication at national level
2012 4 months
2013 3 months
2014 3 months
2015 3 months
2016 4 months
2017 4 months
2018 4 months 
2019 6 months
2020 6 months
2021 6 months
2022 6 months
2023 6 months

From data collection with reference year 2011 onwards, Eurostat asks for the submission of final data for the year N at N+24 months.

For the causes of death statistics between 2009 and 2017 deaths occured in Türkiye and their death certificates are filled out by physicians are covered while 2018 onwards deaths are covered who residing in Türkiye before dying in a certain year. In this context, the causes of death statistics have been internationally comparable according to provinces of residence since 2009, and have been differentiated in terms of coverage in 2018 and later. Deaths and causes of death of deceased persons who are not residents of Türkiye since 2018 are not included in the national statistics. 

Comparability processes are performed between geographical areas (only provinces and districts) for death and causes of death statistics.

 

Beginning from the year 2018, causes of death data are given by usual residence of deceased person covering only residents including foreigners as time-series. Between 2009-2017 causes of death data had been published by usual residence of death events which occured in Türkiye including non-residents.

Since 2009, the causes of death statistics compiled from the Ministry of Health Death Certificates and since 2013 from the Death Notification System (DNS) have been comparable. Before 2009, causes of death statistics were not internationally comparable in terms of disease classification and geographical coverage.
