It found that children aged between seven and 16 now earn an average of Pounds 25.39 a week from their work, with the younger ones doing tasks for parents and friends.
Around 36 per cent of children in Northern Ireland have a part-time job, making them the most likely to work, followed by young people in the South-east at 34 per cent. However, just 19 per cent of children in the North-east and Scotland have a part-time job.
