The total fertility rate in a economy is defined as :

1. A. the number of children born per 1000 people in the population in a year.
2. B. the number of children born to couple in their lifetime in a given population.
3. C. the birth rate minus death rate.
4. D. the average number of live births a woman would have by the end of her child- bearing age.

Answer: D

Explanation

The Total Fertility Rate (TFR) is a demographic indicator that represents the average number of children a woman is expected to have over her entire reproductive period (typically 15-49 years), assuming she experiences the current age-specific fertility rates. Option A describes the crude birth rate. Option B is too general and does not capture the statistical average across a population or the age-specific rates. Option C describes the natural increase or decrease in population, not TFR. TFR is a crucial measure for understanding population dynamics, growth, and replacement levels. This concept is fundamental to population geography and social studies, often discussed in the context of India’s demographic transition.
