Which compares to the age structure of less developed and higher developed countries, specifying the x and y axis. Give an example of natioins with these types of age structure diagrams. What does a high fertility rate tell you about the future of this population.
Given that fertility rate is defined as each woman producing exactly enough offspring to replace herself and her offspring’s father, if the fertility rate is sustained for a generation, then which of the following is true?
Select one:

b. 0 < r < 1
c. r = 0 and there is zero population growth
d. r = 1
