These Web Tables provide comprehensive information on undergraduates who were enrolled in U.S. postsecondary institutions during the 2011-12 academic year. Estimates for enrolled students are presented by attendance status, degree or certificate program, undergraduate major field of study, average grades, student demographic characteristics, financial aid status, credit card debt, work, disability status, and distance and remedial education. These tables are similar to those produced for the 1995-96, 1999-2000, 2003-04, and 2007-08 National Postsecondary Student Aid Study (NPSAS) undergraduate profiles, and they are grouped into six sections: Section 1 focuses on postsecondary enrollment and attendance, displaying estimates for all undergraduates by level, control, and type of institution; student class level; attendance pattern; distance from home; and participation in distance education. Section 2 provides percentage distributions of all undergraduates by degree or certificate program, undergraduate major field of study, and average grades. Section 3 presents estimates by student demographic characteristics, including sex, race/ethnicity, age, dependency status, income, marital status, responsibility for dependents, high school completion status, local residence while enrolled, citizenship status, and parent education level. Section 4 looks at financial aid and credit card debt. These tables summarize financial aid among all, dependent, and independent undergraduates, as well as the percentage of students with credit cards in their own name and, among those who carried a balance, the average and median monthly amount. Section 5 examines students' work experiences while enrolled. Estimates are reported by undergraduates' work intensity while enrolled and, among those who worked, the average and median hours that they worked per week and whether their primary role was work or study. Section 6 presents estimates of undergraduate enrollment by students' disability status and remedial education coursetaking.
