The document discusses the history and current state of literacy around the world. It notes that literacy has improved significantly since 1970, with the worldwide illiteracy rate decreasing by half between 1970 and 2000. However, a UN study from 1998 predicted illiteracy rates may start increasing in the 21st century if changes are not made, since only a quarter of children were in school by 2000. The document explores some proposed solutions such as increasing education funding and reforming education models.
