For most people, a college degree is helpful for flourishing in the labor market. College graduates earn more than workers with less education--on average, about $600,000 more over their lifetimes than workers with only a high school education. College graduates also have much lower levels of unemployment, enjoy better health, and have lower mortality rates. However, not all college experiences have the same benefits. At the high end of the earnings distribution are graduates who majored in fields emphasizing quantitative skills, such as engineering, computer science, economics, and finance. At the low end are graduates who majored in fields that emphasize working with children or providing counseling services, including early childhood education, elementary education, social work, and fine arts. This economic analysis examines how students' career paths after college explain earnings variation "within" majors. To provide college entrants and graduates, as well as career-switchers, with more information about earnings profiles and the diversity of career paths people have pursued with their major, an accompanying interactive is offered (accessible through the full text). Users can view the most common occupations for a given major, comparing earnings by occupation at different stages in the life cycle and for men and women separately. To implement these analyses, the authors use the American Community Survey (ACS) 2011-2013 3-year sample, which contains information about detailed major, occupation, earnings, hours, and demographic variables. This sample is very large, at 3 percent of the U.S. population, which allows for estimating outcomes even for relatively uncommon majors (171 in total) and occupations (217 in total). The findings of the analysis are detailed herein.
