Answer 1

Hint:The general fertility rate of a populace throughout a given time span tells about the proportion of the quantity of live births throughout that time-frame to the quantity of ladies who are in their childbearing years during that time-frame, and furthermore divides by the length of the period.

 Complete answer:
Following fertility takes into consideration more productive and helpful arranging and resource allocation in a particular area. By any chance a nation encounters surprisingly high fertility rates, it might need to construct extra schools or extend admittance to moderate child care. This happened in the United States during the post second world war time when birth rates reached an all time high. During this period, the Total Fertility Rate (TFR) crested at about 3.8, generally double the normal twenty-first century rate in the United States. The bizarrely high number of youngsters conceived during this period left networks ill-equipped. On the other hand, supported low fertility rates may connote a quickly maturing populace, which may put an unnecessary weight on the economy through expanding medical care and government backed retirement costs.

Despite the fact that fertility rates stay well over the replacement rate in numerous parts of the world, the worldwide TFR has declined essentially since 1970. Around then, the world's TFR was generally 4.5, however by 2015 it had plunged to 2.5. In the twenty first century, developed nations by and large had lower fertility rates than developing countries, as the previous would in general have lower childhood mortality rates and more prominent access to contraceptives. Higher fertility rates in non-industrial nations mirrored the requirement for kids to participate in agriculture and other monetary interests as well as the lack of contraceptive access.

Hence, the correct answer is option (B).

Note:The difference between Total Birth Rate (TFR) and General Fertility Rate (GFR) is that TFR is the total of age-specific fertility rates and it weighs the birth cohort for each year with a weight of 1 per birth cohort, the GFR is the average of age-specific fertility rates weighted by the population sizes for the ages.
