Each year, the Institute of International Education (IIE) conducts a survey of the number of foreign students studying in American colleges and universities and U.S. students studying abroad. The results of these surveys are reported in the publication Open Doors. All of the regionally accredited institutions in NCES's Integrated Postsecondary Education Data System (IPEDS) are surveyed by IIE. The foreign student enrollment data presented in the Digest are drawn from IIE surveys that ask institutions for information on enrollment of foreign students, as well as student characteristics such as country of origin. For the 2009–10 survey, approximately 63.0 percent of the 2,673 institutions surveyed reported data.
The flows of U.S. college students studying abroad have been surveyed since 1985–86. Surveys are sent to institutions asking them to provide information on the number and characteristics of the students to whom they awarded credit for study abroad during the previous academic year. Data was obtained from about 990, or 73.5 percent, of the 1,340 institutions surveyed.
