Millennium Development Goal #2 aims to achieve universal primary education by 2015. While progress has been made in some areas through targeted interventions and funding, 69 million children worldwide remained out of school in 2008. Sub-Saharan Africa and Southern Asia account for the majority of out-of-school children and dropouts. The poorest populations, girls, and those in rural areas face the highest risks of not completing primary education due to socioeconomic barriers and lack of access.
