India Population Growth: Trends and Phases
Four phases of demographic change, natural growth, migration and demographic transition
What Does ‘Growth of Population’ Mean?
Definition
Growth of Population: The change in the number of people living in a particular area between two points of time, usually expressed as a percentage. Growth has two components — natural (the difference between birth and death rates) and induced (in-migration minus out-migration).
While natural growth is calculated through the crude birth rate? and crude death rate, induced growth depends on inward and outward population movement. In this chapter the focus is on India's natural population growth, which has been very high and increasing for much of the last century. According to the 2011 Census, the annual growth rate of India's population was 1.64 per cent.
Population Doubling Time
Population doubling time is the time taken by a population to double itself at its current annual growth rate. At a 1.64% growth rate, the doubling time is about 42 years. As India's growth has slowed, doubling time has lengthened.
Decadal Population of India (1901–2011)

Four Phases of India's Population Growth
India's population growth over the last century falls into four distinct phases, each shaped by birth rates, death rates, public health, food security and migration patterns.
Phase I (1901–1921)
Stagnant / Stationary Growth
Both birth and death rates were very high, leaving net growth negligible. The decade 1911–1921 even recorded negative growth (−0.31%) due to famines, plague and the Influenza Pandemic of 1918–19. Poor health, illiteracy and inadequate distribution of food and basic necessities sustained both high mortality and high fertility.
Phase II (1921–1951)
Steady Growth
An overall improvement in health and sanitation reduced mortality, while crude birth rates remained high. The result was a steady, moderate increase. This was achieved against the backdrop of the Great Depression (1929) and World War II.
Phase III (1951–1981)
Population Explosion
A rapid fall in mortality rates combined with a high fertility rate? created a demographic explosion. The annual growth rate reached 2.2%. Post-Independence development plans, modern medicine, and immigration of refugees from neighbouring countries fed the surge.
Phase IV (1981–present)
High Growth with Declining Trend
Growth rate remains high in absolute terms but is now slowing. A downward trend in the crude birth rate — caused by rising age at marriage, female education, contraception and improved quality of life — explains the deceleration. India's Total Fertility Rate has now reached the replacement level (~2.0).
Demographic Transition Theory
The four phases of India's growth align broadly with the Demographic Transition Theory?, which describes how societies move from high birth and death rates to low birth and death rates as they develop. The theory has four classic stages.

Birth rate (red), death rate (blue) and total population (purple). India is currently moving from Stage 3 to Stage 4.
| Stage | Birth Rate | Death Rate | Population Growth | India phase |
|---|---|---|---|---|
| 1. High Stationary | Very high | Very high | Negligible | 1901–1921 |
| 2. Early Expanding | High | Falling | Rapid increase | 1921–1951 |
| 3. Late Expanding | Falling | Low | Slowing growth | 1951–1981 (peak), 1981+ |
| 4. Low Stationary | Low | Low | Stable / near zero | India approaching now |
LET'S EXPLORE — Decadal Growth Decoded
L3 Apply
From the table of decadal population (1901–2011), identify:
- The decade with the highest percentage growth rate.
- The decade with the only negative growth rate.
- The first decade in which India's population crossed the one billion mark.
Guidance
(1) 1961–1971 registered the highest rate at 24.80%, closely followed by 1971–1981 (24.66%). (2) The negative growth occurred in 1911–1921 (−0.31%), mainly because of the 1918 influenza pandemic and famines. (3) India's population crossed one billion at the 2001 Census (1,028 million).
THINK ABOUT IT — The 1918 Decline
L4 Analyse
Why was the decade 1911–1921 the only decade in modern India to show a fall in population? List three contributing causes.
Guidance
(i) The 1918 influenza pandemic killed an estimated 12–18 million Indians. (ii) Famines across northern and central India linked to crop failure. (iii) Poor public health, including epidemics of plague and cholera and very high infant mortality.
Regional Variation in Population Growth
India's growth rate is not uniform across its states. Census data show clearly different patterns by region:
Low-Growth Belt (South)
Kerala, Karnataka, Tamil Nadu, Andhra Pradesh, Odisha, Goa and Puducherry recorded growth rates below 20% per decade. Kerala (9.4%) registered the lowest rate in the country.
High-Growth Belt (NW & N)
A continuous belt from Gujarat through Maharashtra, Rajasthan, Punjab, Haryana, UP, Uttarakhand, MP, Sikkim, Assam, WB, Bihar, Chhattisgarh and Jharkhand averaged 20–25% growth per decade.
Slowing Trend (2001–2011)
Almost every state registered lower growth in 2001–2011 compared to 1991–2001. Andhra Pradesh fell by 3.5 percentage points; Maharashtra fell by 6.7 percentage points.
Exceptions
Tamil Nadu and Puducherry showed a small increase in growth rate during 2001–2011 over 1991–2001 — the only major exceptions to the national slowdown.

Kerala has the slowest growth, while Meghalaya and Bihar show the highest rates.
MAP ACTIVITY — Belts of Growth
L3 Apply
On an outline map of India, prepare a composite bar graph for selected districts/states using total male and female population growth between 2001 and 2011.
Guidance
Locate the high-growth contiguous belt across northern India and shade it. Mark Kerala, Tamil Nadu, AP and Karnataka as low-growth. Use composite bars showing male and female components side-by-side; in many districts you'll find male growth slightly higher in northern states and female growth slightly higher in southern states — reflecting differences in sex ratio and migration.
Adolescents and Youth: A Demographic Frontier
An important aspect of India's population growth is the share of adolescents — those aged 10–19. According to the 2011 Census, adolescents formed about 20.9 per cent of the population, with male adolescents at 52.7% and female adolescents at 47.3% of this group. While this youthful population is regarded as full of potential — the foundation of the demographic dividend? — it is also vulnerable to multiple challenges.
Challenges Faced by Adolescents
Lower age at marriage; illiteracy (especially female illiteracy); school dropouts; low intake of nutrients; high maternal mortality among adolescent mothers; high rate of HIV/AIDS infections; physical and mental disability; drug abuse and alcoholism; juvenile delinquency and involvement in crime.
Government Policies
- National Youth Policy (NYP) 2014: Defines ‘youth’ as persons aged 15–29 years and aims to empower them to realise their potential.
- National Policy for Skill Development and Entrepreneurship 2015: Provides an umbrella framework for skilling activities, aligning them with industry demand.
- Beti Bachao Beti Padhao — gender-sensitive nationwide campaign for girls' education and survival.
DISCUSS — Population Projections
L5 Evaluate
The World Development Report has projected that India's population will touch 1,350 million by 2025. UN estimates suggest about 1,668 million by 2050, after which India's numbers may begin to stabilise. Discuss in groups: what challenges and opportunities does this trajectory pose for India?
Guidance
Challenges: pressure on land, water, food, jobs and infrastructure; rising old-age dependency after 2050. Opportunities: the demographic dividend — a large working-age population that can drive growth, manufacturing, services and global skill exports, provided education, health and employment policies keep pace.

Frequently Asked Questions
What are the four phases of India's population growth?
India's population growth is divided into four phases: Phase I (1901–1921) stagnant or stationary growth; Phase II (1921–1951) steady growth; Phase III (1951–1981) rapid ‘population explosion’; and Phase IV (1981 onwards) high growth with signs of slowing down.
What is demographic transition theory?
Demographic transition theory describes how a country's population moves through three stages: high birth and death rates, then declining death rates with high birth rates causing population explosion, and finally low birth and death rates with stable growth, mirroring economic development.
What is the natural growth rate of population?
Natural growth rate is the difference between the crude birth rate and crude death rate of a population, expressed per thousand people. It excludes the effects of migration.
Why was 1921 called the ‘year of great divide’ for India?
The year 1921 is called the ‘year of great divide’ because before 1921 India's population either declined or grew very slowly due to famines and epidemics, but after 1921 the population began to grow continuously and never decreased again.
What is doubling time of population?
Doubling time is the number of years a population takes to double itself at a given annual growth rate. It is calculated approximately by dividing 70 by the annual growth percentage.
How does migration affect India's population growth?
Migration alters the size and composition of regional populations. International migration is a small share for India, while internal migration (rural-to-urban, inter-state) reshapes density without changing the country's total population.
What is the difference between Phase III and Phase IV of India's population growth?
Phase III (1951–1981) saw a 'population explosion' driven by sharp falls in death rates while birth rates stayed high. Phase IV (1981 onwards) shows continued high growth, but with the annual growth rate beginning to decline as birth rates fall.
