Key Highlights
- India is projected to reach 1.46 billion people in 2025.
- Population will peak at about 1.7 billion in the early 2060s before gradually falling.
- The total fertility rate has slipped to 1.9 births per woman, below the 2.1 replacement level.
- Approximately 68 % of the populace is in the 15‑64 working‑age bracket, creating a potential demographic dividend.
- Life expectancy stands at 71 years for men and 74 years for women, with an ageing cohort already at 7 %.
Detailed Insights
India’s demographic trajectory has shifted dramatically since the mid‑20th century. When the nation had just 436 million people in 1960, the usual family size was close to six children per woman, largely due to limited schooling and reproductive options.
Over the past six decades, increased female literacy, improved access to healthcare and reproductive autonomy have brought the average down to roughly two children today.
With the total fertility rate now at 1.9—below the self‑sustaining benchmark of 2.1—future generations will, without migration, see the population plateau and then ease.
The UNFPA 2025 State of World Population report warns against an alarmist reaction to falling fertility. Instead, it stresses enabling every individual to realise their desired family size.
India’s age structure exhibits 24 % children aged 0‑14, 17 % aged 10‑19, 26 % aged 10‑24, and 68 % within 15‑64, granting the nation a window where a larger working‑force could propel economic growth if supported by job creation and policy.
Meanwhile, the elderly (65 +) fraction climbs from 7 % now, and life expectancy—71 years for men, 74 years for women—indicates a steadily ageing society.
Key Concepts
- Total Fertility Rate (TFR): the average number of children a woman is expected to have in her lifetime.
- Replacement Level: the fertility rate—typically 2.1—needed for a population to maintain its size over generations without migration.
- Demographic Dividend: an increase in the ratio of the working‑age population to dependents, providing potential for economic advancement.
- Life Expectancy: the average period a newborn is expected to live under prevailing mortality conditions.
- Fertility Crisis: a context where fertility falls significantly below replacement, raising concerns about future population sustainability.
