Where can I find a scholarly article on who doesn't go to college/ what their profile is?
On the library Research Station use the Search everything box. Try searching the keyword "educational attainment" using quotes "xxx xxx" around the phrase. Use the Refine options on the left side to select Scholarly/Peer Reviewed".
If you need more help, feel free to come to the Reference Desk on the floor. A librarian is available during these hours who can help you refine your search terms.
