1. Population Pyramids Or
Age /Sex Graphs

2. Population Pyramids
These are illustrations divided into male/female columns that show the distribution of various age groups in a population

3. Patterns of Population Pyramids

4. Rapid Growth Pyramids Pyramids shaped like this illustrate: Poverty
No Birth Control
3rd World Econ.
Low Health Care

5. Slow Growth Pyramid
Slow Growth have: Some health care Good food supply Technology Good living standards

6. Negative Growth Negative Growth has: Great health care
Extensive Birth Control
Educated population
High living standards
High cost of living

7. Creating your Population Pyramid
Take your “Age/Sex Data Table” and divide the total population into the Male 0-4 population
479,894 divided by 6,420,792.
The big number goes into the small to give you a percentage
The answer is: 7.47 which equals 7.5
Use your Handout 1. Age/Sex Graph. You would draw a line half way between 8 and 7 to create a 7.5 space and color that space blue from the bar to the center. When you figure the female population on the other side, you will color it red or pink for female.
Continue the process all the way on both sides to create your population pyramid
