Brazil has the world's 7th largest Gross Domestic Product (GDP), with a population of around 195 million inhabitants, distributed in 27 states (more than five thousand cities). The country has a peculiar higher education system, with a relatively small number of public research universities and a large number of private institutions, both philanthropic and for-profit. Although the system has been growing substantially in the last 15 years, the number of young people attending the university has not exceeded 14% of the 18-25 age cohort eligible to pursue university level study. Approximately 6 million students attend a higher education institution in Brazil— 75% of these students are enrolled in private institutions (approximately half of them are for-profit institutions).
