"In recent years, Sub-Saharan Africa has recorded strong progress in universal primary education for children. The population of school-age children has increased by 20 million and the size of the out-of-school child population has been reduced by almost 13 million or 28 percent compared to the 1990s. International education aid efforts, such as the Education For All (EFA) initiative and the Millennium Development Goals (MDGs), combined with individual government strategies have been key drivers in improving universal primary education in Sub-Saharan Africa. Formulated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) in 1990, the EFA aims to help governments achieve universal primary education by 2015. Similarly, the MDGs, a set of time-bound development goals agreed upon by member states of the UN, prioritize the achievement of primary education for all."
