Over the years, we have made multiple visualizations that focus on how people are different based on their age. It has been awhile though since we updated our visualization that looks specifically how old people are in the United States.
You can use the visualization below to answer the question of what is the average age in the United States, and every state. This year, we have set it up so the different visualizations interact with each other and you are able to more quickly find estimates broken out by sex. Check out the new visualization below.
I used the 2018 U.S. Census Bureau Population Estimates to create this visualization. The data can be found on the Census Bureau website. I then utilized Tableau to visualize the data.
