Complex Bar Graph
What is shown?• Males and Females by age
Why?Demographers use age and sex to help predict info. about a country
How do population pyramids work?Wide base = high % of childrenNarrow base = low % of children
What is a Population Pyramid?

Making Predictions
Look at the shape of these charts, and think about them. Then try to answer these questions on a separate paper.
Which has a higher % of children?
Which is most wealthy, most poor?
Which has the most unemployed?
Which probably has best health care?
Which has most not going to school?
