From 1995-96 to 2007-08, the number of students enrolled in undergraduate education in the United States grew from about 16.7 million to 21 million. These Web Tables provide information on undergraduates during the 1995-96, 1999-2000, 2003-04, and 2007-08 academic years. Estimates are presented for all undergraduates and for undergraduates who attended public 2- and 4-year, private nonprofit, and for-profit institutions by student and enrollment characteristics, hours worked while enrolled, and community service activities. The tables are grouped into three sections. Section 1 presents estimates by selected student characteristics. The tables look at undergraduates' enrollment by age, gender, race/ethnicity, dependency status, marital status and parenthood, income, citizenship, type of high school attended, and parent education. Section 2 focuses on undergraduates' postsecondary enrollment and attendance. The tables display estimates by institution and program level, attendance intensity, in-state attendance, participation in distance education, remedial coursetaking, and attendance at more than one institution. Undergraduate major fields of study are presented for undergraduates who attended public and nonprofit 4-year institutions or were in an associate's degree program at a public 2-year institution. Section 3 looks at undergraduates' work and community service. The tables provide information about students' work intensity while enrolled, average and median hours worked per week, primary role as a student or an employee, participation in community service activities, and the average and median hours volunteered per month. A glossary is included. (Contains 30 tables and 2 endnotes.)
