IV. Analyses by cause of death
1. Mortality probabilities by cause of death
Mortality probability by cause of death means the probability that a person at specific ages will die of specified cause of death in the future.
As for leading causes of death in 2001, the probability of malignant neoplasms is the largest for both sexes at age 0, followed by heart diseases, cerebrovascular diseases, pneumonia.
The mortality probability of three leading causes of death (i.e. malignant neoplasms, heart diseases and cerebrovascular diseases) accounts for over 50 percent for both sexes.

2. Potential years of life lost
Assuming that a certain cause of death is eliminated, a person, who should have died of the cause, would die of the another cause afterwards. As a result, one's life span would be extended. This extension, which is called the potential years of life lost, can be regarded as one's life lost by that cause of death, and it enables to estimate the effect of that cause to one's life expectancy.
In 2001, the order of potential years of life lost at age 0 and 65 is the 1st malignant neoplasms, the 2nd heart diseases, the 3rd cerebrovascular diseases, and the 4th pneumonia for both sexes.
Meanwhile, at age 80 malignant neoplasms shows the largest potential year for male and heart diseases for female.
Potential years of life lost by the three leading causes of death are 8.82 years for males and 7.95 years for females at age 0, 7.12 years for males and 6.61 years for females at age 65, 4.38 years for males and 4.95 years for females at age 80.
