Abstract

We propose a new measure of population ageing, and introduce a new condition called the working-age principle, which is a sensitivity condition to the “thickness” of the working-age population. Then, we characterize our measure by working-age principle and the other standard axioms. We also applied our measure to compute the degree of ageing in China, Japan, Niue, and Singapore, highlighting its importance in capturing the thickness of the labor force.
