7 Creating a Population Pyramid Take your Age-Sex Data Table and observe the population of Country A: 6,420,792Now look at the number of Males from the age of 0-4: 479,894479,894 / 6,420,792 = .0747, or 7.5%You multiply the product by 100 to achieve a percentage, then round up to the nearest half.Now take your Age-Sex Graph and draw a vertical line between 7 and 8 (7.5%) in the bottom left bracket (Males 0-4). Color the area from this line to the centerline blue to represent the percentage of the population which are males from the ages of 0 to 4. When you duplicate this process for the other side, use a pink or red color to represent females from the ages of 0 to 4.Continue repeating steps 1 through 5 all the way to the 100+ bracket using the data from your Age-Sex Data Table.
