India Is Ageing Faster Than It Is Getting Rich, and Its Pension System Isn't Ready

India likes to describe itself, accurately in aggregate terms, as the world's youngest large economy, with a median age around 28-29 years compared to over 38 in the United States and well above 45 in Japan and much of Western Europe. This demographic dividend, the economic boost a country can capture when its working-age population grows faster than its dependent population, has been treated as one of India's central long-term economic advantages, cited by officials, investors and commentators alike as a structural tailwind that other ageing economies would envy. The framing is not wrong, but it is incomplete in two ways that matter enormously for policy: the dividend is regionally uneven and time-limited, and India's institutional preparation for the ageing that will eventually follow it remains strikingly underdeveloped.

The dividend is not evenly distributed

Southern states, including Kerala, Tamil Nadu and Andhra Pradesh, alongside Punjab and Himachal Pradesh, have already completed much of their demographic transition, with fertility rates at or below replacement level for years and ageing populations that in some respects resemble middle-income East Asian economies more than the young-population image most associated with India nationally. Kerala's population aged 60 and above already exceeds 16 percent, a share that will keep climbing as its historically low fertility rate compounds over coming decades, while its working-age population growth has already slowed sharply. States like Bihar, Uttar Pradesh and Madhya Pradesh, by contrast, retain considerably younger population structures and higher fertility rates, meaning they will continue adding working-age population for a longer period.

This divergence creates a genuine policy tension: the states furthest ahead in their demographic transition, and therefore facing pension and eldercare pressures soonest, are frequently not the states receiving the largest fiscal transfers under the Finance Commission's population-weighted devolution formula, which has historically favoured, and continues to somewhat favour despite adjustments, states with larger and faster-growing populations. Southern states have periodically and publicly complained about this mismatch, arguing that their demographic success in stabilising population growth, itself partly a product of decades of investment in female education and healthcare that the devolution formula does not adequately reward, is now being compounded by inadequate fiscal support for the ageing population that success has produced.

Coverage: the number that should worry policymakers most

Far more consequential than the north-south demographic divergence is the near-universal absence of formal retirement income coverage across India's workforce. Estimates from the Ministry of Labour and independent researchers suggest fewer than a quarter of India's workforce, concentrated almost entirely in government employment and larger formal private sector firms covered by the Employees' Provident Fund Organisation, has access to any structured pension or retirement savings arrangement. The remaining three-quarters or more, overwhelmingly informal sector workers, self-employed individuals, agricultural labourers and workers in small unregistered enterprises, have essentially no institutional retirement income mechanism beyond whatever personal savings they manage to accumulate and whatever support family members, particularly adult children, are able and willing to provide in old age.

This matters enormously because India's traditional informal old-age security system, adult children supporting ageing parents within extended or joint family households, is itself weakening under the pressure of urbanisation, migration for work, smaller family sizes following decades of declining fertility, and the simple fact that a shrinking number of working-age children will eventually need to support a growing number of elderly parents as India's own fertility rate has fallen below replacement level nationally. The dividend that a young workforce provides today is, in an important sense, borrowing against a future in which today's workers will themselves need old-age income support that the current system is not building for them at anything like the scale required.

The OPS versus NPS debate and its narrow scope

The most politically charged pension debate in India in recent years has been the fight over whether states should revert from the National Pension System, a defined-contribution scheme introduced in 2004 covering government employees hired after that date, back to the Old Pension Scheme, a defined-benefit arrangement guaranteeing a pension equal to 50 percent of last-drawn salary regardless of how much was actually contributed or invested. Several opposition-ruled states, including Rajasthan, Chhattisgarh, Jharkhand and Himachal Pradesh at various points, announced reversions to the Old Pension Scheme, framing it as restoring dignity and security to government employees, while the central government and most economists have warned that the Old Pension Scheme's unfunded, pay-as-you-go structure creates enormous and growing long-term fiscal liabilities for state governments, with Reserve Bank of India and Comptroller and Auditor General analyses estimating the cumulative unfunded pension liability running into many lakh crore rupees if reversion spread more broadly.

Both sides of this argument have some merit, government employees under the National Pension System have faced genuine market-linked return uncertainty that a defined-benefit alternative would remove, while the states reverting genuinely are creating fiscal liabilities their successors will have to fund decades hence, but the debate's almost exclusive focus on the roughly one crore government employees affected has consumed enormous political and media attention relative to its scale next to the many tens of crores of informal workers with no pension arrangement of either kind.

What exists for the uncovered majority, and its limits

The government has introduced the Atal Pension Yojana, a voluntary contributory pension scheme aimed at informal sector workers with modest guaranteed monthly pension amounts after age 60, and the Pradhan Mantri Shram Yogi Maan-dhan scheme targeted specifically at unorganised sector workers. Enrolment in the Atal Pension Yojana has crossed several crore subscribers, a meaningful number in absolute terms but still a small fraction of the informal workforce it is meant to serve, and average contribution amounts remain low given the modest and often irregular incomes of the target population, meaning the eventual pension payouts, while better than nothing, will not come close to providing genuine retirement income security at the scale India's demographic transition will eventually require.

Closing the window that is already narrowing

India's demographic dividend has perhaps one more generation of favourable working-age population growth left in most states, and considerably less than that in the states furthest along in their transition. Converting that dividend into durable prosperity, rather than watching it dissipate into an old-age income crisis a generation from now, will require substantially scaling up informal sector pension coverage, well beyond the current voluntary, low-contribution schemes, potentially through mandatory small contributions linked to the same GST and digital payment data infrastructure now being used for credit assessment and welfare targeting. The political system's current preoccupation with the Old Pension Scheme fight, however genuinely important to the government employees involved, is a debate about the smaller and already better-protected slice of India's workforce, while the far larger and more urgent coverage gap facing everyone else receives a fraction of the policy attention its eventual scale demands.
