Abstract

Aim
The aim of the study is to improve the measurement of ageing taking into account characteristics of populations and in particular changes in life expectancy.

Method
Using projected life tables, we calculate prospective old age dependency ratios (POADRs) to 2060, placing the boundary to old age at a moving point with a fixed remaining life expectancy (RLE) for all countries of East Asia.

Results
POADRs grow less rapidly than old age dependency ratios (OADRs). For example, in the Republic of Korea, the OADR is forecast to increase from around 0.1 in 1980 to around 0.8 in 2060, while the POADR is forecast to increase from around 0.1 to 0.4 over the same period.

Conclusion
Policy makers may wish to take into account the fact that the increases in measures of ageing will be slower when those measures are adjusted for changes in life expectancy.
