For the past 10 months, children in Indonesia’s Banten province have been commuting to school on narrow bamboo rafts—along a river best known to tourists for its whitewater rapids—because local authorities still haven’t fixed a bridge that collapsed in January in a flood. In China, a group of children in Guangxi province, some as young as four years old, also travel to school along a river on flimsy rafts because other routes to the school, along a flooded mountain path, are even more dangerous.
Progress has slowed most in Sub-Saharan Africa, home to more than half of the world’s out-of-school children. In countries like Nigeria, the population is outpacing the build-up of needed infrastructure. Only 62 percent of children in the Philippines attended high school between 2007 and 2008. In India, the number of out-of-school children fell 67 percent from 2003 to 8.1 million in 2009.
