The decadal growth rate of population during 2001-2011 in India was :

Question

Accepted Answer

The decadal growth rate of population during 2001-2011 in India was +17.64%, which corresponds to Option 3. Here is a detailed explanation justifying why Option 3 is correct and why the other options are incorrect:

1. **Explanation for Option 3 (+17.64):**
   - The decadal growth rate is calculated by comparing the population at the beginning and end of the decade. According to the Census of India 2011, the population growth rate from 2001 to 2011 was indeed +17.64%. This figure is derived from the official census data, which is the most reliable source for demographic statistics in India. The growth rate reflects various factors, including birth rates, death rates, and migration patterns during that decade.

2. **Why Option 1 (+21.54) is incorrect:**
   - A growth rate of +21.54% would imply a significantly higher increase in population than what was recorded. The actual growth rate was lower, as confirmed by the census data. This option overestimates the population growth and does not align with the official statistics.

3. **Why Option 2 (+20.54) is incorrect:**
   - Similar to Option 1, a growth rate of +20.54% is higher than the actual recorded growth rate. While it might seem plausible, it does not match the official census data, which clearly states the growth rate as +17.64%. This option also overestimates the growth.

4. **Why Option 4 (+18.64) is incorrect:**
   - Although +18.64% is closer to the correct figure than Options 1 and 2, it still does not accurately reflect the official growth rate. The census data specifies the growth rate as +17.64%, making this option slightly higher than the actual figure.

In conclusion, Option 3 (+17.64) is the correct answer as it accurately represents the decadal growth rate of the population in India from 2001 to 2011, based on the official census data. The other options do not align with the documented statistics and therefore are incorrect.
