Child labor refers to work performed by children that deprives them of their childhood and interferes with their education and development. Poverty is a major driver of child labor, as families force their children to work to earn money for basic needs. During the 18th century Industrial Revolution, child labor increased as factories needed more workers and parents sent their children to work for cash. In recent years, conventions and agreements like ILO 138 and 182 have aimed to eliminate the worst forms of child labor and set minimum ages for employment through free, compulsory education. Organizations like UNICEF also work to address the needs of children worldwide.
