Longevity Gains Slow: Generations Born After 1939 May Not Reach 100 on Average
For more than a century, each new birth cohort has tended to live longer than the one before. Yet a sweeping analysis of mortality across 23 wealthy nations finds that the pace of longevity gains has slowed dramatically. People born between 1939 and 2000 are unlikely to reach the century mark on average, a sharp turn from optimistic forecasts that long life would become even more commonplace. While individuals will still outlive their predecessors, the transformative jump in lifespan that defined the 20th century appears to be tapering off. This news matters far beyond Western capitals: Thailand and many other aging societies are watching closely as longer life spans collide with rising health and care costs, shifting the balance of family responsibilities and public budgets.
