Traditional factors are also important. The established female role in certain countries dictates that women will not fit into traditional roles if they become educated. There is a pervasive notion in some nations that educated females will not get married nor have children. Therefore, many families raise daughters solely to take over the household duties in order release the mother for paid labor. Such cultural practices restrict the education of females and promote child employment. The acceptance of social class separation perpetuates child labor as well. For example, people of India's lower castes are expected to perform manual labor and therefore are more apt not to attend school. Often parents in developing countries assign different roles to their children. This has been called child is specialization and may increase the number of working children. This phenomenon involves certain siblings going to school while others work. Many times this depends on the birth order where the oldest is the one who attends school.
