Discussion Questions
Now that we know what this is, what does it tell us about a country’s population?
Why might this information be important to a leader of a country?
Do you think population pyramids for all American cities would look the same as the United States
population pyramid? Why or why not?

A population pyramid shows the size of age groups by sex within a population. Look carefully at the four population pyramids below. They show information from the 2000 Census about four American cities.
Think about the people who live in each of these cities. Suppose you took a photograph of a group of people in each city. What might they look like? What type of clothing might they be wearing? Your teacher is projecting four photographs. Try to match each one to one of the pyramids below.

Analyzing Population Pyramids
1) What is Demography?
How might demographers use population pyramids?
2) What are total fertility rate and replacement rate?
Why would the bottom of the pyramids be the best place to apply these terms?
Which pyramids represent countries at or about replacement level?
Which pyramids represent countries below replacement level?
3) What is life expectancy?
Why would the top of the pyramids be the best place to apply this term?
Which pyramids represent countries with higher life expectancy?
Which pyramids represent countries with lower life expectancy?
4) What is dependency ratio?
How might the three shades of color (light, medium and dark) on the pyramids help you figure out dependency ratio?

1. Locate the cohort in the data table and on the pyramid grid.2. If the cohort is already drawn, color it in. Use blue on the left ide for males.
Use red on the right side for females.3. If the cohort is missing, complete it. Use blue on the left o draw in the percent
of the population that is male. Use red on the right to draw in the percent of thepopulation that is female.
