India’s demographic transition is no longer a future concern; it is an unfolding reality. By 2035, nearly 140 million Indians will be over the age of 60. By mid-century, that figure will approach 300 million—close to one-fifth of the population. For policymakers, this is not simply a social statistic. It is a structural variable that will shape labour markets, public finances, institutional capacity, and social cohesion for decades.
