Introduction: India's Population — Scale and Significance

Scale of India's Population

India is home to one of humanity's greatest demographic stories. Covering only 2.4% of the world's land area, India sustains 17.5% of the world's population — a density paradox that defines its development challenges and opportunities alike.

At Census 2011, India's population stood at 121.09 crore (1.21 billion), growing from 102.87 crore in 2001. By April 2023, according to UN projections, India surpassed China to become the world's most populous nation (~144 crore), though this awaits confirmation from Census 2021 (still pending as of early 2026).

Why This Matters

India's population size creates both enormous pressures (on land, water, food, employment, urbanisation) and extraordinary opportunities (the demographic dividend — a young workforce that, if educated and employed, can drive rapid economic growth).

Relevance for RPSC

• PYQ 2023 directly asked about the 1981–2011 "high growth with declining trend" phase
• Census data (sex ratio, literacy, density, growth rate) is tested in both 2-mark and 5-mark questions
• The interaction of population with physiography and resources is a recurring theme (T089 covers Rajasthan specifically)
• Policy questions — National Population Policy, demographic dividend, urbanisation — are increasingly common
