Youth unemployment has skyrocketed worldwide over the past decade to some 88 million, according to a new study by the International Labour Office (ILO), reaching an all time high with young people aged 15 to 24 now representing nearly half the world's jobless. "Global Employment Trends for Youth 2004", a new analysis prepared by the ILO's Employment Strategy Department, found that while youth represent 25 per cent of the working age population between the ages of 15 and 64, they made up as much as 47 per cent of the total 186 million people out of work worldwide in 2003.
