Child Labor

Child labor is the employment of children under an age determined by law or custom. This practice is considered exploitative by many countries and international organizations. Child labor was utilized to varying extents through most of history, but entered public dispute with the beginning of universal schooling, with changes in working conditions during industrialization, and with the emergence of the concepts of workers' and children's rights.
Child labor can be factory work, mining[ or quarrying, agriculture, helping in the parents' business, having one's own small business (for example selling food), or doing odd jobs. Some children work as guides for tourists, sometimes combined with bringing in business for shops and restaurants (where they may also work as waiters). Other children are forced to do tedious and repetitive jobs such as assembling boxes, polishing shoes, stocking a store's products, or cleaning. However, rather than in factories and sweatshops, most child labor occurs in the informal sector, "selling on the street, at work in agriculture or hidden away in houses — far from the reach of official labor inspectors and from media scrutiny."
According to UNICEF, there are an estimated 218 million children aged 5 to 17 in child labor worldwide, excluding child domestic labor. The most controversial forms of work include the military use of children as well as child prostitution. Less controversial, and often legal with some restrictions, are work as child actors and child singers, as well as agricultural work outside of the school year (seasonal work).
