Examining Age/Gender Distributions with Population Pyramids

Population pyramids provide a data visualization often used in demographic analysis because they provide a condensed but powerful illustration of a population’s age distribution by gender. You can use the ChartGraphics tool to create population pyramids for the U.S., states, counties and other areas as reviewed in this section. For example, examine Census 2020 population by 5-year age group by gender for your area of interest.

A population pyramid is essentially two bar charts, one for the male population on the left and the other for the female population on the right. The base of the pyramid, or bottom of the chart, has the youngest population (ages 0-4) and the top has the oldest (ages 85 and older). The following pyramids illustrate how Orange County, CA has changed from 2000 to 2020.
