In 2000, the 25 countries with the most out-of-school primary-age children were home to 66 million out-of-school primary-age children. By 2012, they had reduced this number by 42% to 38 million.

India, Bangladesh, Uganda, Zambia and Tanzania all reduced their out-of-school populations by more than 60%, collectively reducing the number of out-of-school children by more than 20 million.

However, progress was uneven. In seven countries – Nigeria, Indonesia, the Philippines, Eritrea, Cote d’Ivoire, Madagascar and Chad, the number of out-of-school children increased. In Nigeria, it increased by more than 60% to 11 million.

The graphic below shows the out-of-school population in 2000 and 2012 for the 25 countries with the largest out-of-school population in 2000. The area is proportional to the number of out-of-school primary-age children.
