Steps such as the abolition of school fees, investments in teaching infrastructure and resources, and school meals from the World Food Programme helped drive enrollment up by millions. Yet despite the significant progress of many countries, the world fell short of meeting its goal of Universal Primary Education (UPE). In sub-Saharan Africa as of 2013, only about 79% of primary school-age children were enrolled in school. 59 million children of primary-school age were out of school, and enrollment of girls continued to lag behind that of boys. Disparity between genders is partially due to females being excluded from school for being pregnant.
