The median age of India is about 29.2 years in 2026, according to the medium-variant projection of the UN World Population Prospects (WPP) 2024. Half of India’s roughly 1.48 billion people are younger than this and half older. India is still one of the younger large countries, but it is ageing steadily: the median age was about 20 years in 1950 and is projected to reach about 39 years by 2050.
Quick Answer
Median age of India (2026): about 29.2 years (UN WPP 2024, medium variant). 2025: about 28.8 years. 1950: about 20 years. 2050 (projected): about 39 years. 2100 (projected): about 48–49 years. World median age: about 31 years. Meaning: the age that divides the population into two equal halves. Why it matters: India is in its demographic dividend phase, with about two-thirds of people of working age (15–64).
What Median Age Means
The median age is the middle value when everyone in a population is lined up by age. It is not the same as the average (mean) age. A low median age means a young population with many children and young adults; a high median age means an older population with fewer births and longer lives.
Two forces push the median age up:
- Falling fertility: fewer births shrink the youngest age groups. India’s total fertility rate is now below the replacement level of 2.1.
- Rising life expectancy: more people survive into old age.
How India’s Median Age Has Changed
| Year | Median age (years) | Stage |
|---|---|---|
| 1950 | about 20 | High birth and death rates |
| 1990 | about 21–22 | Fertility starts falling |
| 2010 | about 25 | Working-age bulge forming |
| 2026 | about 29.2 | Demographic dividend phase |
| 2050 | about 39 (projected) | Ageing accelerates |
| 2100 | about 48–49 (projected) | Older, shrinking population |

India Compared With Other Countries
| Country | Approx. median age (mid-2020s) |
|---|---|
| Japan | about 49–50 |
| China | about 40 |
| United States | about 38–39 |
| India | about 29 |
| Bangladesh | about 26–27 |
| Pakistan | about 20–21 |
| Niger | about 15 |
India is much younger than China, so its working-age population will keep growing after China’s has started shrinking.
Variation Across States
India’s states are at different points of the demographic transition:
- Older states: Kerala, Tamil Nadu, Himachal Pradesh, Punjab and Andhra Pradesh have low fertility and longer lives, so their median age is well above the national figure.
- Younger states: Bihar, Uttar Pradesh, Jharkhand, Madhya Pradesh and Rajasthan still have higher fertility, so their median age is lower.
This gap shapes debates on migration, the use of population in delimitation and the Finance Commission’s devolution formula.
Demographic Dividend and Ageing
The dividend
With about 68% of the population aged 15–64, India has a large working-age share and a falling dependency ratio. The dividend is not automatic: it pays off only if young people get education, skills, health and jobs, and if more women join the workforce.
The ageing challenge
The share of people aged 60 and above is rising quickly and is expected to roughly double by 2050. That raises questions about pensions, old-age healthcare and care for the elderly, especially in the older southern states. See our note on Population Ageing and the Dependency Ratio.
