London - Almost 170 million youth are trapped in child labour, deprived of education and facing a life without decent jobs, says the International Labour Organisation.
From India's brick kilns to the cotton fields of Uzbekistan and Bolivia's sugar plantations, child labourers are more likely to have to settle later in life for unpaid work for the family or low-paying jobs, the ILO said in its annual "World Report on Child Labour".
"Children who drop out of school and join the labour force early are more disadvantaged later in life because of a lack of education and basic skills," aid Patrick Quinn, a senior ILO advisor.
Protective environment
Despite an overall decline in child labourers by one-third since 2000, about5 million children remain in slavery-like conditions, making up a quarter of the world's modern-day slaves, the ILO said.
The Asia-Pacific region has the largest number of child labourers with almost 78 million, or 9.3%, while sub-Saharan Africa has the highest rate with 59 million or more than 21%.
Many of them are working under conditions that deprive them of a nurturing and protective environment and expose them to stress and trauma, the ILO said.
More than half of all child labourers - 85 million - put their health at risk by working in hazardous jobs, such as mining and construction, said the report, released ahead World Day Against Child Labour on Friday.
Rising youth unemployment, which stands at 75 million globally, can also drive child labour as poor job prospects may stop parents from investing into their children's education, the report said.
The ILO urged world leaders when they decide on new development goals in September to come up with a coherent policy to tackle child labour and the lack of decent jobs for youth.
Decent work means employment that is productive and delivers a fair income, job security, social benefits and equal opportunities.
Forced to work
A global push for access to primary education as part of the United Nations Millennium Development Goals has helped to push the overall child labour numbers down, Quinn said.
The number of child labourers aged five to 14 dropped to 120 million in 2012, from 186 million in 2000, he said.
The decline has been less rapid among older children, as many leave school early and are forced to work to make money for their impoverished families, particularly in rural areas.
Between 20 to 30% of children in low-income countries are working by the age of 15 and even more leave school before that, the report said.
"It will not be possible to achieve overall child labour elimination without addressing child labour among older children," the report said.
