Estimating life expectancy using an age-cohort model in Taiwan
Journal of Epidemiology and Community Health
|April 1, 1996
Summary
Calculating cohort life expectancy is crucial for public health. A new age-cohort model reveals life expectancy in Taiwan increased more steeply than previously estimated.
Area of Science:
- Demography
- Public Health
- Actuarial Science
Background:
- Life expectancy is a key public health and actuarial metric.
- Current life tables assume constant mortality, which is unrealistic.
- Cohort life tables require impossible individual follow-up data.
Purpose of the Study:
- To develop a method for calculating cohort life expectancy without direct follow-up.
- To address the limitations of current life table methodologies.
Main Methods:
- An age-cohort model was employed for estimation.
- Taiwan male mortality data from 1951-1990 were utilized.
Main Results:
- The increment in life expectancy over time in Taiwan was found to be steeper than previously reported.
- This finding contrasts with estimates derived from current life table techniques.
Conclusions:
- The proposed method is easy to implement using standard mortality data.
- The methodology warrants further investigation for broader application.
