Book excerpt: Enrollment in graduate and first-professional education in the United States has increased in recent years--from about 2 million students in fall 1995 to more than 2.6 million students in fall 2007 (Snyder, Dillow, and Hoffman 2009, tables 206 and 207). Increasing enrollments overall raise questions regarding the types of students entering graduate and first-professional schools: is the profile of the typical graduate or first-professional student changing too? One example of such change is the rising enrollment of female students: from 1995 to 2007, the percentage of women among all graduate and first-professional students rose from 54 to 59 percent (Snyder, Dillow, and Hoffman 2009, tables 206 and 207). The Web Tables presented here use data from the 1995-96, 1999-2000, 2003-04, and 2007-08 National Postsecondary Student Aid Study (NPSAS) to examine trends in the profiles of graduate and first-professional students from 1995-96 to 2007-08. These tables group students by their graduate degree level: master's, doctoral, and first-professional, and examine how their demographic and enrollment characteristics have changed over time. Table 1 provides an overview of change in the distribution of graduate and first-professional students by graduate level and degree program. Table 2 examines trends in graduate and first-professional enrollment in different types of institutions. Tables 3 through 8 illustrate trends for selected student demographic characteristics such as age, sex, race/ethnicity, marital/dependent status, citizenship, and parental education. Tables 3 and 4 focus on master's students, tables 5 and 6 on doctoral students, and tables 7 and 8 on first-professional students. Tables 9 through 14 show trends for student enrollment characteristics including time of entry into graduate education, attendance status, enrollment in distance education courses and degree programs, and employment intensity while enrolled. Tables 9 and 10 focus on master's students, tables 11 and 12 on doctoral students, and tables 13 and 14 on first-professional students. A glossary is included. (Contains 28 tables and 3 endnotes.).
