Number of registered deaths by leading cause of death, 2001 - 2025

Number of registered deaths by leading cause of death, 2001 - 2025

Since 2001, the classification of diseases and causes of death has been based on the International Statistical Classification of Diseases and Related Health Problems (ICD), 10th Revision.  The disease groups used for ranking causes of death have also been redefined according to the ICD-10, with new categories added.  As a result, figures from 2001 onwards may not be directly comparable with those for earlier years, which were compiled using the ICD-9.  Therefore, figures prior to 2001 are presented in a separate table.

Notes:
The figures are based on deaths registered under the Births and Deaths Registration Ordinance (Cap. 174, Laws of Hong Kong) during the specified period.

The corresponding disease codes are shown in brackets.

† According to the ICD 10th Revision, when the morbid condition is classifiable under Chapter XIX as "Injury, poisoning and certain other consequences of external causes", the codes under Chapter XX for "External causes of morbidity and mortality" should be used as the primary cause of death.
