* Directly related: Some studies look at whether a graduate's job directly aligns with their major. This often shows a lower percentage than expected, especially in fields with high competition or oversaturation. Many graduates end up in jobs that require some skills learned in college but aren't a direct application of their degree.
* Indirectly related: A broader definition includes jobs where skills and knowledge gained during college, even outside the specific major, are applicable. This would significantly increase the percentage. Critical thinking, communication, and problem-solving skills are examples of transferable skills.
* Definition of "use": Does using a degree mean working in a field directly related to the major? Does it mean leveraging skills learned during college? Does part-time use count? All of these factors influence the outcome.
* Data limitations: Surveys and studies on this topic have methodological limitations, including self-reporting bias and difficulty in accurately classifying job roles.
In summary, while you won't find a precise number, various studies suggest a significant portion of graduates work in jobs *somewhat* related to their degree, though a smaller percentage work in jobs directly related to their major. The percentage varies widely depending on the field of study, economic conditions, and the definition of "using" the degree.
