Census Bureau data shows 34.4% of adults age 25 to 34 have a bachelor’s degree. It’s also becoming more common for jobs to require a four-year degree. Among more than 800 careers tracked by the Bureau of Labor Statistics, 275 require at least a bachelor's degree. Those jobs are also higher paying. People with a bachelor’s degree earn $1,173 per week, compared to the $907 median weekly earnings for all workers. (We previously looked at the 10 highest paying jobs you can get with a bachelor's degree.)

To understand what college students are studying, we looked at data on the most popular bachelor’s degrees attained by adults age 25 and older in every state, including Washington, D.C. We used Census data, which look at broad degree categories, rather than specific majors. So a degree in business administration and international business would both fall into the category of “business” in the Census data.

A bachelor’s degree in business is the most popular by far. About 14.4 million people in the U.S. have a business degree, which is 20.3% of all people with a bachelor’s degree. In every state, business is either the first- or second-most popular field of study.

A business degree could also be handy later in life. More than one quarter of new entrepreneurs are between the ages of 55 and 64.

The second-most popular degree was in the field of education (8.6 million people nationally), followed by science and engineering related fields (6.8 million people across the country).

The least common field for a bachelor’s degree was in multidisciplinary studies, at just 516,502 people in the U.S. (0.7% of all people with a bachelor’s degree). The next least popular degrees were in physical sciences and communications. Both of those fields account for less than 4% of all people with a bachelor’s degree.
