In the 2011-12 academic year, about 4 million students were enrolled in graduate degree programs in the United States. These students were pursuing a wide variety of degrees in many different fields, both academic and professional. These Web Tables use data from the 2011-12 National Postsecondary Student Aid Study (NPSAS:12) to present estimates on the demographic and enrollment characteristics of students in graduate-level programs and how they financed their graduate studies. The tables in Section 1 (tables 1.1 to 1.4) provide percentage distributions of graduate students by graduate degree program and demographic, institutional, and enrollment characteristics, including distributions by sex, race/ethnicity, age, attendance status, marital status, citizenship, employment, and income. The tables in Section 2 (tables 2.1 to 2.3) present these demographic and enrollment distributions for students in master's degree, academic doctoral, and professional doctoral degree programs and within broad groupings of field of study. The tables in Section 3 (tables 3.1 to 3.10) first focus on average tuition and costs of attendance by enrollment and institutional characteristics. The final series of tables distinguish financial aid by source and by type, providing the percentage of students receiving each kind of aid and the average amounts received. These financial aid estimates are disaggregated by selected enrollment and institutional characteristics.
