The institutional affiliation should be the location where the research was conducted, most often a college or university. In some cases, research may have been supported by more than one institution. For these instances, only include two affiliations if both schools offered substantial support to the research and only list two affiliations for every author. What should you do if you were not affiliated with an academic institution when the research was conducted? In this instance, the APA suggests listing your city and state of residence in place of the academic affiliation.
