There is a wide variety of guess estimates as to the number of working children under 15 years of age, ranging from 200 to 400 million worldwide. Even if such estimates were to be regarded as realistic, more global totals do not provide insight into the various forms of the practice and the problems associated with child labour. According to ILO's Bureau of Statistics, there are at least 120 million children between the ages of five and 14 who are fully at work in developing countries alone.
In the just concluded 92nd session of the ILO in Geneva, Switzerland, report has it that about 700,000 children are found in domestic labour in Indonesia, 559,000 in Brazil, 250,000 in Haiti, 264,000 in Pakistan, 200,000 in Kenya and 100,000 in Sri Lanka. If those for whom work is a secondary activity were included, the total working children in this age group would be more than 250 million.
Lack of reliable data makes it difficult to know the problem and can be counter-productive when it comes to setting national priorities for urgent action. However, following experimental work in the early 1990s, the ILO has developed statistical survey methodologies to assist countries in the collecting and improving information base on child labour.
So far Child Labour Surveys based on recently developed methodologies by the ILO have been carried out in selected areas in several countries of the world, while child labour surveys are yet to have impact in Nigeria amongst other countries in the developing world. Child labour by definition refers to work that is mentally, physically, socially, morally dangerous and harmful to children.
