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.

Connecticut’s 38.6% share of residents with at least a bachelor’s degree is the second highest in New England and fourth highest in the United States. In general, higher educational attainment leads to higher annual incomes and in Connecticut, a four-year college degree is more valuable than in most other states. The typical college educated adult in Connecticut earns $61,257 a year, more than in every other state except for New Jersey, and nearly $10,000 more than is typical nationwide.
