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
