I found this amazing interactive map of the U.S. labor force from 1950 to 2000. Each delineation on the graph shows a different occupation, as well as the percentage of the labor force that occupation makes up. As you move to the right or left, you can see that percentage change for each decade. This would be a fantastic resource for U.S. history classes and could provide some interesting discussions about why certain jobs gained in popularity while others declined (the most obvious example being the decline of farmers).

Happy infographing, y’all!
