The present research is aim to examines the ageing in the context of mortality selection in India. The study uses two indicators of ageing: demographic ageing and biological ageing. In order to examine the effect of early life mortality selection on ageing, I plotted the age-specific mortality rate from ages 0-1 to 80-84 for selected Indian cohorts born during 1900-2005. Finding shows that later cohort have lower young-age mortality rate and lower old age mortality rate than earlier cohorts, which support the cohort evolution hypothesis. Moreover, I observed that in spite of lower young-age mortality and old age mortality of later cohort, the rate acceleration of mortality after age 40 is steeper for later cohort than earlier cohort, which indicates the presence of mortality selection mechanism. Preliminary findings on effect of mortality selection encouraging me to examines whether the current old age mortality is real or artifact of mortality selection.
