Explanation & Answer

Here is your answer attached, it was great working with you. Let me know if you have any questions.

1. Total fertility rate (TFR) is defined as the total number of children born to a woman
during her lifetime. This value is what organizations like United Nations uses to
determine the future population size. The UN publishes a high/low projection for
population based on the TFR. The high estimate assumes the TFR will be more than
the current and the low estimate assumes the TFR will be less than the current. If
the TFR is lower, then the world population is projected to decline and vi...
