"Twenty years ago, a young girl starting school in sub-Saharan Africa could expect to receive about five years of education during her entire life – and part of that time might have been spent repeating grades. Today, she can expect to spend about eight years in a classroom. But the boy sitting next to her is likely benefit from an extra 18 months of instruction. This remarkable yet uneven progress comes to life in a new atlas on gender and education, released by UNESCO for International Women’s Day 2012, celebrated on 8 March."
