8. Compton, California
One of the oldest cities in the county but with a rather young population with an average age of 25, compared to U.S. median of 35. The city of Compton is an impoverished area, and this has its negative effect on the education in the city with only 48.0% of people having a high school education and only 5.9% have bachelor’s degrees.
