Up until the millennium, the number of students enrolled at the university rose exponentially. In 1992, UiO implemented a restriction on admissions for all of its faculties for the first time. A large part of the explanation for the high student numbers was thought to be found in the poor job market. In 1996, there were 38,265 students enrolled at UiO. This level was approximately 75 per cent above the average during the 1970s and 1980s. The strong rise in student numbers during the 1990s was attributed partially to the poor labour market.
