Using national data, the present study first investigated interstate college migration. Unlike existing studies of interstate college migration, this study also tracked students to college graduation to explore their post-graduation migration, such as leaving to other states after graduating from in-state institutions and returning to home states after graduating from out-of-state institutions. While a single equation approach has been widely used in migration research, this study used multi-level logistic regression that is rather new in the area of institutional research. In addition to states' economic conditions, certain institutional characteristics were found to influence differently depending of types of migration. States by Region are appended.
