Population Age Structure - Pyramids (30 pts) Your task today is to make use of the data provided by the U.S. Central Intelligence Agency to analyze and compare of two nations in the world. Two additional sites that will be useful in your Weekly Assignment next week are from the Population Reference Bureau and U.S. Census Bureau website. Get familiar with those as well, while you’re in the ETC.

PART I: After browsing around this CIA Link a little (there’s an amazing amount of information available!), pick TWO nations (that are fairly different in population measures), use this site or either of those given above, and your knowledge of populations, to complete the table below:

1 2 Population Measure ______Total Population Crude birth rate Crude death rate R-value (show your calculation!) Given rate Migration rate Infant mortality rate

2. Show a general sketch of the two population pyramids for the two countries chosen above. Country: Country:

PART II: 1. Find an example of the population pyramid types in 2012 (not examples from class or above, please): Expansive: ______Growth Rate: ______Stationary: ______Regressive: ______Questions- ANSWER for one of your two nations: ______

PLEASE answer these questions here and/or on a separate sheet of paper. (mostly 1 pt each) 1. Which gender has the higher population in the youngest age groups on your pyramid? Which gender has the higher population in the oldest age group?

2. What does the shape of your country’s histogram (pyramid) mean for your country? Is it increasing in population size, decreasing, or close to ZPG yes, BUT MORE IMPORTANTLY, compare the pyramid shape to the growth rate (with and without migration!) and say what’s happening now. (3 pts)

Look closely at the pyramid for your country to answer questions 3-5 SHOW SET-UP FOR YOUR MATH! 3. Determine the percentage of the population that is 65+.

4. Determine the percentage of the population that has yet to reach childbearing age (females below 14).

5. Determine the percentage of the population that is at post-reproductive age (females 50+).

6. What do these numbers say about the prospects for future growth?

7. What is the migration rate for your country? (Especially note if it’s positive or negative.)

8. What are some social/economic problems that might occur as a result of your population’s age structure?

9. Does your country have a baby boom in it? If so, in what years were the “boomers” born?

10. If you had a business and you wanted to capitalize (make $$) on your information about the population age structure, what would you sell? Why?

11. In one paragraph, compare and contrast your two nations. In what ways are their population’s age structures similar? How are they different? EXPLAIN WHY (culturally, historically) this might be. (3 pts)
