USCollegeSearch.org, a fairly simple but good chart showing the relationship between unemployment rates and education levels. Although lacking a good title, this chart does a great job of communicating one message really well.
The Bureau of Labor Statistics has found that people who finish degree programs in college earn much more over the course of their lifetimes than those who only earn high school diplomas or drop out of college. Sometimes the difference can be over a million dollars before retirement. But even more interesting, it was noted that people with undergraduate and graduate degrees manage to stay employed for longer periods, but also find jobs they qualify for more quickly. They spend less time searching and more time working.
