Note(s):
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. Hence, caution should be exercised when interpreting the trend of diseases across 2000 and 2001.

Colorectal cancer corresponds to codes 153-154 in ICD-9 and C18-C21 in ICD-10.
