Answer to Problem 1TY

Correct answer: The average total fertility rate that is needed for zero population change across the world is 2.3. Hence, the correct answer is option d.

Explanation of Solution

Reason for correct answer:

For the determination of an average number of children produced by a woman across the world, the total fertility rate is used and it is the most common metric. At present, it has been calculated that the average fertility rate for zero population change is less than 2.5 children per woman. The correct value for the average total fertility rate is 2.3.

Option d. is given as “2.3”.

An average total fertility rate of 2.3 is required for zero population change across the world. Hence, the correct answer is option d.

Reasons for incorrect answer:

Option a. is given as, “1.7”.

An average total fertility rate of 1.7 can be defined as a sub-replacement fertility rate of children born per woman. Hence, option a. is incorrect.

Option b is given as, “1.9”.

An average total fertility rate of 1.9 can be defined as a sub-replacement fertility rate of children born per woman. Hence, option b. is incorrect.

Option c. is given as, “2.0”.

The average total fertility rate which is required for zero population change is 2.3 instead of 2.0. Hence, option c. is incorrect.

Option e. is given as, “2.5”.

The average total fertility rate which is required for zero population change is 2.3 instead of 2.5. Hence, option e. is incorrect.

Hence, the options a., b., c., and e. are incorrect.

Conclusion

An average total fertility rate of 2.3 can be defined as an average rate of production of offspring by a woman across the world for no change in the population.
