This report presents summary statistics on application and registration patterns of applicants applying for fall entry into full-time study in their first year of university programs. Those few students who applied directly to the institutions may not be included in these statistics. In 2001, there were 325,139 applications by 92,863 applicants, of whom 51,555 actually registered at an Ontario university. Tables present data about application and registration ratios, applicants and registered applicants by institution and institutional category, and student preferences and geographic origin. Three appendixes describe program groupings and geographic groupings and explain one table's headings in more detail. (Contains 15 tables and 13 figures.) (SLD)
