The Demographic Transition Theory (DTT) is highly relevant for India, providing a framework to understand the country’s evolving population dynamics and the interplay between development, economic growth and demographic changes.
Let’s examine India’s Growth trends in the context of DTT.
India’s demographic growth can be classified into three phases.
Phase- I: Pre-Independence (High stationery)
- Before 1921, India’s population growth was almost stagnant, marked by high birth rates and high death rates (Synonymous to Stage 1 of the DTT). The country faced frequent famines, epidemics, wars, and poor healthcare, resulting in high mortality rates that offset the high birth rates.
- The Year of Great Divide (1921) is considered a turning point, after which population growth began to accelerate due to improvements in healthcare and sanitation, setting the stage for India’s population growth in the post-independence era.
Phase II: 1947–1971 (Early Expanding)
- In the decades following independence, India transitioned, which is (Similar to Stage 2 of the DTT) marked by a significant decline in death rates due to improved medical care, public health measures and better sanitation.
- However, birth rates remained high, leading to rapid population growth, characteristic of Stage 2. India’s population increased from 361 million in 1951 to 548 million in 1971, reflecting the population explosion.
- This phase also saw economic challenges, as rapid population growth strained resources and hindered the country’s development.
Phase III: 1971–2001 (Late Expanding)
India transitioned to the next phase with the introduction of national family planning initiatives in 1952. There was growing awareness about contraception and family planning, which helped lower birth rates.- The decline in fertility rates was driven by increased literacy, urbanization, and better healthcare, leading to slower population growth.
- The Total Fertility Rate (TFR) started declining, and the population growth rate peaked at 2.22% per annum in the 1970s.
- By 2001, India’s population had crossed the 1 billion mark, reaching 1.02 billion.
| Fertility rate is a demographic measure that indicates the average number of children born to women of reproductive age (typically 15-49 years) in a given population. It is often used to assess population growth and can provide insights into social, economic and health conditions within a society. |
Phase IV: 2001–Till Now (Slowing Growth Phase)
- India entered a slowing growth phase in the 21st century, where both birth rates and death rates have dropped significantly. The population growth rate slowed to 0.88% in 2023 according to the World Bank, with TFR decreasing to 2.0 by 2021, approaching replacement level (2.1).
- This phase saw increasing urbanization, improved education, and greater access to healthcare, especially for women, all contributing to the decline in fertility.
- However, there remain regional disparities, with northern states like Bihar, Uttar Pradesh, and Madhya Pradesh continuing to experience higher growth rates compared to southern states like Kerala, Tamil Nadu, and Karnataka, which achieved population stabilization earlier due to better education, healthcare, and family planning.
Population Projection for India
India’s population pyramid will undergo a dramatic transformation from 1950 to 2100, reflecting shifts in fertility rates, mortality rates, and life expectancy. These changes will have significant implications for the country’s demographic structure, economic dynamics, and social policies.
Population Pyramid Shift from 1950 to 2100
| 1950 (Past) | 2025(Current) | 2100 (Future Projection) |
|
Shape: Broad at the base, tapering quickly toward the top. Characteristics:
|
Shape: Still broad at the base, but the middle (working-age population) starts to widen. Characteristics:
|
Shape: More column-shaped or top-heavy, with a smaller base. Characteristics:

Government Initiatives to Control Population Growth and Mitigate Consequences
- National Population Policy (2000): Aims to stabilize the population by 2045 through improved healthcare, education, and family planning.
- Family Planning and Reproductive Health: Programs like the National Family Planning Program and Mission Parivar Vikas promote contraception access and reproductive health education, targeting high-fertility areas.
- Economic and Employment Policies: Initiatives like Skill India and MGNREGA create jobs, provide vocational training, and alleviate poverty, reducing pressure on resources.
- Health and Public Welfare: Schemes like Ayushman Bharat and Janani Suraksha Yojana improve healthcare access, maternal and child health, and reduce mortality rates.
- Infrastructure Development: The Smart Cities Mission focuses on urban growth management through improvements in housing, transportation, and sustainable development.

Solutions to Tackle Population Growth and Population Explosion
- Promote Family Planning: Access to affordable contraceptives and sterilization programs.
- Improve Education: Especially for women, to delay marriage and reduce fertility rates.
- Enhance Healthcare: Reducing infant and maternal mortality rates.
- Empower Women: Economic and social empowerment to reduce dependence on large families.
- Increase Employment Opportunities: Reducing poverty to lower fertility rates.
- Cultural and Behavioural Change: Addressing cultural and religious resistance to small families.
India’s huge population (now the world’s largest at 1.42 billion!) provides a massive workforce and market — a key economic driver. But it also puts pressure on resources, cities, and infrastructure. Understanding this dual nature is essential for policy-making and exams. Our upsc notes pdf explains this balance clearly with facts and examples.
The DTT tracks how countries move from high birth/death rates to low ones. India’s journey fits perfectly into its stages — from stagnant growth pre-1921 to declining fertility in recent decades. We break down each phase and India’s transition in our upsc notes pdf, making it super easy to revise.
Right now, India has a youthful structure, but by 2100, the pyramid is projected to flip — more elderly, fewer children. That means rising healthcare needs and a shrinking workforce. It’s a classic demographic shift and crucial for UPSC. Visuals and pyramid analysis are available in our upsc notes pdf.
From the National Population Policy (2000) to family planning programs, and even schemes like Ayushman Bharat and Skill India, there’s a multi-pronged approach. These initiatives aim to reduce birth rates and support sustainable development. You’ll find all key policies listed in our upsc notes pdf on population.
