An Investigation of Population Entropy

Population entropy was introduced to measure the effect of changing mortality on the life expectancy. Employing Keyfitz’s (1977) formulation, Nagnur (1986) found the entropy decreased while the life expectancy increased, signifying a process of convergence. Hill (1993) employed Demetrius’ (1976, 1979) formulation and stressed the variance of d(x) function as a measure of population entropy but found it remained almost constant while the life expectancy increased. This project proposed to examine and compare the composition of both Keyfitz’s and Demetrius’ entropy measures, and study the process of convergence in Taiwan.
