Problem 2

"Doubling time" is the number of years it would take a population to double in size at its current growth rate. The doubling time is found by dividing 69.3 by the growth rate. Calculate the doubling time for the following countries:
a) Afghanistan: growth rate 3.5 percent
b) Belgium: growth rate 0.2 percent
c) Canada: growth rate 1.0 percent
d) Bangladesh: growth rate 1.6 percent

Problem 5

Suppose that fruit flies on Kiwi Island live for three days. On their first day they are considered young and reproduce with a TFR of 2 . Half of their offspring are female. On the second day the flies are middle-aged and cannot reproduce. On the third day they are considered old and they cannot reproduce. All fruit flies live to old age. Indicate the number of fruit flies on Kiwi Island on days 2, 3, and 4 under each of the following scenarios:
a) On day 1 there are equal numbers of males and females in each age category, including six old flies, four middle-aged flies, and two young flies.
b) On day 1 there are two males and two females in each age category.
c) On day 1 there are 100 young male flies and 100 middle-aged female flies.
d) On day 1 there are equal numbers of males and females in each category, and there are six young flies, four middle-aged flies, and two old flies.

Problem 6

Starting with the situation in Part (d) of Problem 5, on what day would the population stabilize, in the sense that it would be the same as the day before, in each of the following situations:
a) With no change from the scenario in Problem 5.
b) Fruit flies increase their life span by one day, but can still only reproduce on their first day.
c) One young male and one young female fruit fly die each day before reproducing.

Problem 7

Income and education levels are on the rise in many parts of the world.
a) How do you think your own postcollege boost in income (after you land your first "real" job) will affect your consumption behavior?
b) How do you think your decision to attend college will affect the timing of any children you might have relative to if you ended your schooling after high school?
c) Doyou think most people would provide similar answers? What does this suggest about policy and preparation for related demographic changes?
