Question
Consider the following demographic parameters :
1. Average number of daughters born to a woman
2. Sum of age-specific fertility rates
3. Magnitude of completed family size
Which of the above parameters reflect/reflects total fertility rate?
The correct answer is
2 and 3
Demographic Parameters and Total Fertility Rate
This question requires identifying which demographic parameters accurately reflect the Total Fertility Rate (TFR). We need to analyze each listed parameter.
Understanding Total Fertility Rate (TFR)
The Total Fertility Rate (TFR) is a demographic indicator representing the average number of children a woman would have if she experienced current age-specific fertility rates throughout her reproductive years.
Analysis of Demographic Parameters
- 1. Average number of daughters born to a woman: This metric focuses specifically on daughters, not the total number of children. It is related to the Net Reproduction Rate, not the Total Fertility Rate.
- 2. Sum of age-specific fertility rates: This is the standard definition and calculation method for TFR. Age-specific fertility rates (ASFRs) for women within reproductive age groups are summed up to estimate the total fertility.
- 3. Magnitude of completed family size: TFR is used as a measure to estimate or predict the average completed family size. It reflects what the final family size would be based on current fertility patterns.
Conclusion on TFR Reflection
Based on the analysis:
- Parameter 2 is the direct calculation basis for TFR.
- Parameter 3 represents the expected outcome or implication of TFR.
Therefore, parameters 2 and 3 reflect the Total Fertility Rate.
