Step 1: Understanding the Concept:
India's demographic history is a classic example of the Demographic Transition Model.
Over the last century, India has passed through several stages where the relationship between birth rates and death rates has shifted, resulting in different growth patterns.
Step 2: Detailed Explanation:
Let's analyze the four demographic phases defined by Indian geographers:
Phase I (1901–1921): This is the "Stagnant Phase." During this period, growth was very slow and even recorded a negative growth rate in the 1911-1921 decade.
This was due to high birth rates being matched by extremely high death rates caused by poor medical facilities, lack of sanitation, frequent famines, and epidemics like the Spanish Flu.
Thus, Statement 1 is correct.
Phase II (1921–1951): This is the "Steady Growth Phase." After 1921 (known as the Year of the Great Divide), the death rate began to drop due to improved health services and better transport for food distribution.
However, the birth rate remained high, leading to a consistent and steady increase in population.
Thus, Statement 2 is correct.
Phase III (1951–1981): This is the "Population Explosion Phase." After independence, centralized planning led to rapid improvements in healthcare and sanitation.
The death rate plummeted while the birth rate remained very high, resulting in an annual growth rate of over \(2.2%\).
Thus, Statement 3 is correct.
Phase IV (1981–Present): In this current phase, the population is still growing, but the rate of growth is declining.
Contrary to Statement 4, the crude birth rate has decreased significantly due to rising female literacy, urbanization, and better family planning.
Thus, Statement 4 is incorrect.
As statements 1, 2, and 3 are correct, option (B) is the right choice.
Step 3: Final Answer:
Based on historical census data, the first three phases are correctly described, while the fourth phase incorrectly states that the birth rate is increasing.
Therefore, the correct answer is (B).
