The Total Fertility Rate (TFR) indicates the average number of children that would be born per woman during her childbearing years. Generally, countries with higher TFRs are expected to have faster-growing populations, as more children are born per woman.
Based on the data you provided:
- Niger: 7.75
- Kenya: 4.56
- Iraq: 3.86
- Venezuela: 2.48
- United States: 2.05
- Vietnam: 1.83
- United Kingdom: 1.66
- Italy: 1.31
- South Korea: 1.21
Among the options given:
A. South Korea (1.21) has a very low TFR. B. Iraq (3.86) has a moderate TFR. C. Kenya (4.56) has a fairly high TFR. D. Niger (7.75) has the highest TFR of all the countries listed.
Given that Niger has the highest TFR, it is most likely to have the fastest-growing population. Therefore, the best answer is:
D. Niger
