Child labour refers to the employment of children at regular and sustained labour. This practice is considered exploitative by many international organizations. In many developed countries, it is considered inappropriate or exploitative if a child below a certain age works (excluding household chores, in a family shop, or school-related work). An employer is usually not permitted to hire a child below a certain minimum age. This minimum age depends on the country and the type of work involved.
According to UNICEF, there are an estimated 250 million children aged 5 to 14 in child labour worldwide, excluding child domestic labour. Child labour accounts for 22% of the workforce in Asia, 32% in Africa, 17% in Latin America, 1% in US, Canada, Europe and other wealthy nations.
The incidence of child labour in the world decreased from 25 to 10 percent between 1960 and 2003, according to the World Bank.
