With millions of Americans saddled with seemingly insurmountable levels of student debt, some are calling into question the practicality of obtaining a four-year college degree. Still, the share of Americans who have earned a bachelor’s degree rose last year. As of 2016, 31.3% of Americans age 25 and older had a bachelor’s degree or higher — up from 30.6% the previous year and 29.1% in 2012.

Better educated populations tend to benefit from a range of positive socioeconomic outcomes. American adults with a bachelor’s degree generally earn higher incomes, are less susceptible to serious financial hardship, and are more desirable candidates for employers.

Adults with college degrees are more likely to have higher paying jobs than those with only a high school diploma. In Colorado, 39.9% of the adults age 25 and older have at least a bachelor’s degree, well above the 31.3% share of American adults. Partially as a result, the typical Colorado household earns $65,685 a year, well above the $57,617 the typical American household earns.
