The "Current Term Enrollment Estimates Report" series is published every December and May by the National Student Clearinghouse Research Center. It provides national enrollment estimates by degree level, institutional sector, enrollment intensity, age group, gender, major field as well as state-level enrollment estimates. Starting in fall 2020, state-level enrollment data are also shown by institution sector. As with the previous reports, the "Spring 2021 CTEE" provides estimated postsecondary enrollment numbers based on the Clearinghouse universe of institutions, after accounting for data coverage rates. For spring 2021, overall postsecondary enrollment dropped by 3.5 percent, or 603,000 students. This one-year decline is seven times larger than the rate of decline reported in spring 2020 (-0.5%). Undergraduate students accounted for all of the decline, dropping 4.9 percent, or over 727,000 students, from spring 2020. In contrast, graduate enrollment jumped by 4.6 percent or more than 124,000 students over the same period. [For "Current Term Enrollment Estimates: Spring 2020," see ED609890.]
