Notes:

*

Age-standardised rates are compiled based on the world standard population specified in GPE Discussion Paper Series: No.31, EIP/GPE/EBD, World Health Organization, 2001.

 

 

Data in the above charts from 1996 onwards are compiled based on the population estimates under the "resident population" approach instead of the "extended de facto" approach. Also, the 2016 Population By-census conducted from June to August 2016 provides a benchmark for revising the population figures compiled since the 2011 Population Census. Population-related figures from 2012 to 2015 have been revised accordingly.

 

 

Classification of diseases and causes of death is based on the International Statistical Classification of Diseases and Related Health Problems (ICD) 10th Revision from 2001 onwards. Figures from 2001 onwards may not be comparable with figures for previous years which were compiled based on the ICD 9th Revision.
