According to an education for all global monitoring report published by Unesco in October, 71 million adolescents of lower secondary school age were out of school in 2010, with three out of four living in south and west Asia and sub-Saharan Africa. The last of these regions has doubled the number of students enrolling over the period, yet has the world's lowest total secondary enrolment, at 40 per cent in 2010. Private schools have stepped in to plug the gap.
