Just over 9% of all students attended more than one institution during the 2012-13 academic year. In each year studied, nearly three-fourths of all mobile students had at least one enrollment at a 2-year public institution. In each of the included years, students in the 20 and under age group had the highest mobility rates, followed by students in the >20 to 24 age group. In each of the years studied, the percentage of women attending more than one institution within a single year was one and a quarter percentage points higher than the rate for men. The following charts are presented in this report: (1) Postsecondary Student Mobility Rate: 2011-2013 (by sector of earliest enrollment within academic year); (2) Distribution of Mobile Students by Sector Combinations; (3) Mobility Trend by Age Group: 2011-2013; and (4) Mobility Trend by Gender: 2011-2013.
