Population Profiles are graphs that show data collected from a specific population based on certain variables such as age, race, income, and sex. Typically the chart will have two categories on the x-axis and one on the y-axis. These charts are often used to show population growth in Human Geography. This chart shows the population by sex and age in the District of Columbia in 2010. It can be determined that the largest group are females from the age of 20-30.
