Contributions of various major causes of death to life expectancy in Singapore, 1980-1990.

This paper considers the contributions by age of the various major groups of deaths to the increase in life expectancy at birth between 1980 and 1990 for both sexes in Singapore. Sixteen cause groups were used in the study. The data were analysed using LIFETIME, a personal computer package with a wide variety of methods for mortality investigations. Respiratory diseases made the largest contribution to the increase in life expectancy for both sexes. In contrast, ischaemic heart disease made a negative contribution of 1% in the gain in female life expectancy but contributed 12% improvement for males. Life tables for Singaporean males and females in the year 2000 were projected by extrapolating the mortality trends observed in earlier periods. The calculations show that the life expectancy at birth in the year 2000 to be 74.72 years for males and 79.48 years for females.
