Four Phases of Population Growth
- Phase I — Stagnant (1901–1921): high birth + high death rate; 1921 = "Year of the Great Divide"
- Phase II — Steady increase (1921–1951)
- Phase III — Rapid/Explosive growth (1951–1981)
- Phase IV — High but declining growth (1981–2011)
- 7
Most and Least Populous States (2011)

- 8
Population Distribution Pattern
- Northern Plains and Peninsular Coasts are most densely populated (>300 persons/sq km)
- Himalayas, Western Rajasthan, and northeast hilly states are sparsely populated (<50 persons/sq km)
- Distribution is highly uneven, driven by physiography, agriculture, and urban employment
- 9
Total Fertility Rate (TFR)
- TFR in 2011: 2.4 children per woman — declined to 2.0 (NFHS-5, 2019–21)
- Now below the replacement level of 2.1
- Indicates India is approaching demographic stabilisation
- 10
Urbanisation (2011)
- Urban population: 37.7 crore (31.16% of total) — up from 28.6 crore (2001)
- India has 7,935 cities/towns; Mumbai UA (~18.4 million) is the largest city
- Urban population share expected to reach 50% by 2050
- 11
Dependency Ratio and Demographic Dividend
- ~52% in working age group (15–64 years); 31% below 15; 5% above 65 (2011)
- Creates a demographic dividend opportunity
- Must be harnessed through education and employment
- 12
Census 2021 Status
- Census 2021 was delayed due to COVID-19; not yet completed as of 2026 exam context
- All official India population data refers to Census 2011 figures
- NFHS-5 (2019–21) provides some updated indicators
What makes India's population scale significant for development and RPSC exams?
India's population scale matters because a very large population concentrated on a small share of the world's land creates both severe development pressures and a rare demographic-dividend opportunity.
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, which is still pending as of the 2026 exam context. The United Nations Population Fund's India Population 2025 dashboard puts India's total population at 1,463,900,000, underlining why India now anchors most global population discussions.
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 on the National Population Policy, demographic dividend, and urbanisation are increasingly common

PREDICTED Predicted RAS Questions
Based on PYQ trends and 2026 syllabus analysis
1 5M Explain the phase of "high population growth with declining trend" in India (1981–2011). (PYQ 2023 style)
Model Answer
During 1981–2011, India's population growth rate declined decade by decade (23.79% → 21.54% → 17.64%) due to rising female literacy, improved contraceptive access, and government family planning. Yet absolute additions remained massive (~18 crore per decade) because demographic momentum — the large young cohort entering reproductive age — kept absolute growth high. This paradox: falling rate but large numbers = "high growth with declining trend" — a characteristic of Phase IV of India's demographic transition.
