The data for this visualization comes from the Current Population Survey which is conducted by the U.S. Census Bureau. It uses estimates from 1983-2018. The high and the low for each sex and age group are provided on the lines. More information about this topic can be found here. I used Excel to make get the data in a usable form and Tableau to create the visualization.
