In many countries of the developing world, and especially in rural areas, girls who attend school do so for only a few years, often dropping out when they are in their early teenage years.
The reasons for school dropout vary. Education for girls is not considered important or is actively opposed in some societies. Often girls are expected to marry at an early age; few stay in school afterward, especially if they have children. Economic factors can be just as important because families sometimes cannot afford school fees for any or all of their children. When decisions must be made among siblings in regards to education, boys nearly always are given priority.
