Explanation: Population growth rate is a critical demographic indicator that measures the change in population over a specific period, typically expressed as a percentage. For Andhra Pradesh, the growth rate from 2001 to 2011 was 10.98%, which is the correct answer among the given options.
To understand this concept, it is essential to know how population growth rate is calculated. The formula for population growth rate is:
\[ \text{Population Growth Rate} = \left( \frac{\text{Population at the end of the period} - \text{Population at the beginning of the period}}{\text{Population at the beginning of the period}} \right) \times 100 \]
For the period 2001-2011, the population of Andhra Pradesh increased from approximately 7.62 crores in 2001 to 8.47 crores in 2011. Using the formula:
\[ \text{Population Growth Rate} = \left( \frac{8.47 \text{ crores} - 7.62 \text{ crores}}{7.62 \text{ crores}} \right) \times 100 \]
\[ \text{Population Growth Rate} = \left( \frac{0.85 \text{ crores}}{7.62 \text{ crores}} \right) \times 100 \]
\[ \text{Population Growth Rate} = 0.1115 \times 100 \]
\[ \text{Population Growth Rate} = 11.15\% \]
The actual reported growth rate is 10.98%, which is very close to the calculated value, indicating a moderate increase in population over the decade.
Understanding the population growth rate is crucial for planning and policy-making in areas such as healthcare, education, and infrastructure. It helps in assessing the demographic trends and planning for future needs. The growth rate of 10.98% for Andhra Pradesh reflects a balance between natural increase (births minus deaths) and migration patterns, which are key factors influencing population dynamics.
It is important to note that population growth rates can vary significantly between different regions and time periods. Factors such as economic conditions, healthcare improvements, and family planning policies can influence these rates. Therefore, it is essential to analyze the specific context and data for accurate interpretation and planning.
