Contains academic data on 384 four-year colleges and universities in the United States. Includes longitudinal and cross-sectional data from multiple sources. The collection is organized into 9 datasets based on the unit of analysis and whether identifiers linking the data to particular institutions are present; 7 of the datasets can be linked by a common identifier variable (PROJ_ID), and 2 cannot be linked due to confidentiality agreements. The 7 identifiable datasets contain information on institutions, university systems, programs and academic departments, earned degrees, graduate schools, medical schools, and institutional academic rankings over time. Data regarding student enrollments, average SAT and ACT scores, and tuition and fees has been recorded, as well as institutional information concerning libraries, research activity, revenue and expenditures, faculty salaries, and quality rankings for program faculty. The identifiable datasets also include census information for neighborhoods surrounding IDA colleges and universities. The 2 non-identifiable datasets contain confidential survey responses from IDA institution presidents, chancellors, provosts, and academic vice presidents; survey questions pertained to governance structures, institutional goals and achievements, and solicited opinions on current and future issues facing the respondent's institution and higher education in general.
