Detailed Solution:
The correct answer is “2.1”.
The total fertility rate (TFR) of a population is the average number of children that would be born to a woman over her lifetime if:
1) she was to experience the exact current age-specific fertility rates (ASFRs) through her lifetime.
2) she was to live from birth until the end of her reproductive life.
TFR of about 2.1 children per woman is called Replacement-level fertility.
