Indicators derived from population forecasts

Derived indicators	Definitions	Forecast changes
Old age dependency ratio (OADR)	Ratios of older populations to working age populations	Serious increase in ratios in future Shifts upwards in threshold ages for retirement
Labor force dependency ratio (LFDR)	Ratio of older retired population to employed population at all ages or ratio of inactive population to active population at all ages	Increase in ratios diminishes Older population needs support to continue working
Productivity weighted labor force dependency ratio (PWLFDR)	Ratio of inactive population (all ages) to active population (all ages), weighted by productivity for education grade	This measure remains relatively constant for 2020−2070 in China
