Table 2 Total enrolment, medical schools in Mexico, 1990–2001. In general, enrolment in the career of medicine in Mexico has shown non-linear behavior for the past 25 years. It was at the beginning of the 1990s when it showed a downward trend, mainly because of the official policy implemented in the mid-1980s to halt the high demand to enrol that was evident at that time. Yet on average, enrolment increased by 22.8% during the 1990–2001 period.
