Starting with a hypothetical population of 14,000 people and an even age distribution (1,000 in each age group from 1-5 to 66-70 years), assume that the population initially has a total fertility rate of 2.0 and an average life span of 70 years. Using the spreadsheet for exercises 1-3, estimate how the population will change from this generation to the next under each of the following conditions.
a. Total fertility rate and life expectancy remain constant.
b. Total fertility rate changes to 4.0; life expectancy remains constant.
c. Total fertility rate changes to 1.0; life expectancy remains constant.
d. Total fertility rate remains at 2.0; life expectancy increases to 100.
e. Total fertility rate remains at 2.0; life expectancy decreases to 50.
F. Total fertility rate changes to 4.0; life expectancy increases to 100.
