उत्तर और व्याख्या · explanation in English
Answer: (d) एक महिला की गर्भधारण आयु (चाइल्ड-बेअरिंग एज) के अंत तक उनसे जन्मे जीवित बच्चों की औसत संख्या
Total fertility rate (TFR) is the average number of children a woman would have by the end of her child-bearing years, given the fertility rates of a particular period. It is counted per woman, not per couple and not per 1,000 people.
- ✓ (d) The WHO defines TFR as the average number of children a hypothetical group of women would have at the end of their reproductive period if they experienced the fertility rates of a given period. NCERT reads a TFR of 1.7 as the average woman having 1.7 children.
- ✗ (a) Births per 1,000 people in a year is the crude birth rate, which is measured against the whole population, not against women.
- ✗ (b) TFR is measured per woman and is not a count of children per couple.
- ✗ (c) Birth rate minus death rate is the natural rate of population growth.
Remember · TFR = average children per woman over her child-bearing years; replacement level is about 2.1, and India's TFR fell to 2.0 in NFHS-5 (2019-21).
