The correct Answer is:
To solve the question regarding the intrinsic rate of natural increase, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Concept**: The intrinsic rate of natural increase (often denoted as 'R') is a measure of how quickly a population can grow under ideal conditions. It is influenced by the birth and death rates within that population. 2. **Identifying the Formula**: The intrinsic rate of natural increase is calculated using the formula: \[ R = B - D \] where \( B \) is the birth rate and \( D \) is the death rate. 3. **Analyzing the Options**: The question provides multiple options. We need to determine which option correctly describes the intrinsic rate of natural increase: - Option 1: Incorrect (not specified) - Option 2: Correct (it is the difference between birth rate and death rate) - Option 3: Incorrect (it mentions immigration which is not part of the intrinsic rate) - Option 4: Incorrect (it incorrectly combines birth and death rates with immigration and emigration) 4. **Conclusion**: Based on the analysis, the correct answer is option 2, which states that the intrinsic rate of natural increase is the difference between the birth rate and the death rate. ### Final Answer: The intrinsic rate of natural increase is the difference between the birth rate and the death rate (Option 2). ---
