India’s latest National Family Health Survey reveals striking progress in maternal and child well-being: institutional deliveries have surpassed 90%, full vaccination among toddlers has reached 87.1%, and early breastfeeding is nearly universal. Viewed from New Delhi, the numbers signal a young nation reaping the rewards of sustained public health investment. Yet this advance stands in sharp contrast to the demographic stagnation gripping much of the developed world. Across Europe, natural population growth has stalled. France’s 2025 data mark a symbolic tipping point as births no longer offset deaths, while Germany—where the death rate has exceeded the birth rate since 1972—now counts over 22% of its population as aged 65 or older. The continent’s demographic engine is sputtering, forcing an ever-heavier reliance on immigration to sustain labour forces.

The pressures of demographic transition are not confined to Europe. In North Africa, a region once synonymous with high fertility, birth rates have plummeted. Morocco recorded a historic low of 1.97 children per woman in 2024, down from over seven in the 1970s; Tunisia’s rate has slipped to 1.53, well below replacement. Analysts in Rabat warn that the coming years will bring a shrinking workforce and rising old-age dependency, echoes of European anxieties. Further east, Iran faces a different facet of the same challenge: a marriage crisis. Officials report that over 18 million Iranians have never married, with economic insecurity—jobs, housing, credit—cited as the principal brake on family formation. Without swift intervention, the country risks a deepening baby bust.

Indonesia’s demographic outlook is bifurcated. Health authorities estimate that 4 to 6 million couples suffer from infertility and need medical assistance, even as the government confronts a rising tide of non-communicable diseases. The deputy health minister recently flagged colorectal cancer as an emerging threat, pushing for enhanced screening and management. These strains come as Indonesia, like much of Southeast Asia, navigates its own fertility transition. While the nation’s youthful profile remains an asset, the growing burden of chronic illness and the need for assisted reproduction underscore the complexity of maintaining a healthy, productive population.

Taken together, these snapshots reveal a world where demographic destinies are diverging sharply—but all are converging on a common challenge: adapting social and economic systems to new population realities. For India, immediate success in maternal health must be sustained as the country undergoes epidemiological transition. For aging societies from Berlin to Casablanca, the imperative is to redesign pensions, immigration, and labour markets. The North African fertility plunge, in particular, serves as a warning that the demographic dividend can evaporate faster than policymakers expect. As demographers in London note, the 21st-century state will be defined less by its borders than by its capacity to manage the lifecycle of its citizens—from birth, through health, and into a dignified old age.
