Population growth rate depends upon

Options

A. Birth rate
B. Death rate
C. Age-sex ratio
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding Population Growth Rate**: The population growth rate refers to the change in the number of individuals in a population over a specific period of time. It is a crucial metric for understanding demographic changes.

2. **Factors Influencing Population Growth Rate**:
- **Birth Rate**: This is the number of live births per thousand people in a given year. A higher birth rate contributes to a faster population growth rate.
- **Death Rate**: This is the number of deaths per thousand people in a given year. A lower death rate contributes to a higher population growth rate, as fewer individuals are dying.
- **Age-Sex Ratio**: This refers to the distribution of individuals of different ages and sexes within a population. A balanced age-sex ratio can influence reproductive rates and overall population dynamics.

3. **Interrelation of Factors**:
- The birth rate and death rate are direct indicators of population change. If the birth rate exceeds the death rate, the population will grow. Conversely, if the death rate exceeds the birth rate, the population will decline.
- The age-sex ratio affects the potential for future births. A population with a higher proportion of individuals in reproductive age will likely have a higher birth rate.

4. **Conclusion**: The population growth rate is influenced by the birth rate, death rate, and age-sex ratio. These factors interact to determine whether a population is growing, stable, or declining.

**Final Answer**: Population growth rate depends upon birth rate, death rate, and age-sex ratio.
