Conclusion • Population willincrease & then stabilize • Proportion & number of elderly willincrease • Ageing: a challenge in coming years • By late 2020s one-quarter will be elderly • “Old Old” category willincrease • Females & widows among the elderly willincrease
Conclusion • Most elderly don’t have any retirement income • Large numbers will be retiring: They need to have pension or other scheme • Elderly can live about 2 decades of retirement • Demographic environment is conducive for economic takeoff: Presently lowest level of dependency
