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
