This study is to investigate how major causes of death influence korean life expectancy. The causes of death analyzed are one of the following 7 categories, namely ; Infectious and Parasitic Diseases(001-139), Tuberculosis(010-018), Malignant Neoplasms(140-208), Hypertensive Diseases(401-405), Cerebrovascular Diseases(430-438), Chronic Liver Diseases and Cirrhosis(571), Accidents(E800-E999).
The major findings are as follows
1. Average ages of people died by cerebrovascular diseases, hypertensive diseases, malignant neoplasms are 68.3, 67.5, 62.1 respectively, and ages distribution of people died from all of seven causes of death show A-shape pattern in male and adverse Lshape pattern in female.
2. The probabilities of eventually dying of malignant neoplasms mask the peaks at 40 in male and 20 in female, and 60 in male and 50 in female in case of cerebrovascular diseases. Among the curve of eventual death probability, the curve of malignant neoplasms is higher than any other curve before 60 in male, and cerebrovascular diseases is the highest after 60 in female.
3. These life tables are reflecting accurately the effects of age distribution on the specific cause of death in the survival curves of these tables. It was observed that the survival curve of accidents is going sharply downward with aging while curves of cerebrovascular diseases and hypertensive diseases decline from the age of 50 in male and 60 in female. They are going sharply downward after 60 in age.
4. The life expectancy is prolonged by eliminating malignant neoplasms as causes of death ; 2.36 years in male and 1.96 years in female. Accidents is the top contributing cause of death in case of male which influence to the life expectancy. By eliminating accidents as a cause of death life expectancy gains 2.45 years in male.
