Population Growth Rate of India from 2001 to 2011: 17.64%

The population growth rate of a country is a measure of how the population changes over a specific period of time. In the case of India, the population growth rate from 2001 to 2011, as per the Census 2011, was 17.64%.

Factors Influencing Population Growth:
There are several factors that influence population growth, including birth rate, death rate, and migration. Let's examine each of these factors in detail:

1. Birth Rate: The birth rate refers to the number of births per thousand individuals in a population. A high birth rate contributes to population growth, while a low birth rate leads to population decline.

2. Death Rate: The death rate represents the number of deaths per thousand individuals in a population. A high death rate can result in population decline, while a low death rate contributes to population growth.

3. Migration: Migration refers to the movement of individuals from one place to another. It can be internal (within the country) or international (between countries). Migration can impact population growth by increasing or decreasing the population size.

Population Growth Rate Calculation:
The population growth rate is calculated using the following formula:

Population Growth Rate = ((Population in Year 2 - Population in Year 1) / Population in Year 1) * 100

In this case, the population in 2001 was compared to the population in 2011 to calculate the growth rate.

Explanation of Answer:
According to Census 2011, the population of India in 2001 was approximately 1.028 billion, while the population in 2011 was around 1.21 billion. Plugging these values into the population growth rate formula, we get:

Population Growth Rate = ((1.21 billion - 1.028 billion) / 1.028 billion) * 100
= (0.182 billion / 1.028 billion) * 100
= 0.177 * 100
= 17.64%

Therefore, the correct answer is option D) 17.64%.

It is important to note that population growth rates can vary over time and are influenced by various socio-economic factors. Understanding population growth rates helps policymakers and governments plan for the needs and challenges associated with a growing population.
