Why in News?

Data on median age across world regions (2000 vs 2023) shows Europe has the oldest population (median age 42) and Africa the youngest (19), a 23-year gap. India's median age stands at about 28.4 years.

Key Data

•       Europe: 37 → 42 | Northern America: 34 → 38 | Oceania: 30 → 33

•       Asia: 25 → 32 | Latin America: 23 → 31 (fastest increase, 8 years) | Africa: 17 → 19

•       Median age is the age that divides a population into two equal halves, one younger and one older.

Causes of the Divergence

•       Fertility rates: Africa's Total Fertility Rate (TFR) is high (about 4+); Europe's is far below the replacement level of 2.1.

•       Life expectancy: Higher in Europe because of better healthcare and living standards, which pushes the median age up.

•       Demographic transition stage: Africa is in an early-to-mid stage (high birth rate, falling death rate); Europe is in a late stage (low birth and death rates).

Implications

•       Youthful societies (Africa, India): a potential demographic dividend, but only if backed by education, skilling and jobs. Otherwise it becomes a demographic burden or unrest.

•       Ageing societies (Europe, East Asia): a shrinking workforce, rising pension and health costs, and a dependence on immigration.

•       For India: the dividend window is open until roughly 2040s. States differ widely (Kerala is ageing, while Bihar and UP are young).

Way Forward

•       Invest in health, education and skills (human capital); raise female labour force participation.

•       Prepare for ageing through social security, geriatric care and a silver economy.
