From the World Development Report 2013
621 million young people are “idle”—not in school or training, not employed, and not looking for work. Rates of idleness vary across countries, ranging between 10 and 50 percent among 15- to 24-year-olds.

Was there any consideration in this study for discouraged youth who have stopped searching for employment due to lack of success in their job searches?
These are really shocking numbers, but honestly: I can't really beliefe this is true.
Worldwide, we count 1.2 billion young people. 621 million are "idle" (51.75 %).
So how can then rates of idleness range "between 10 and 50 percent"?
This measure shown here includes both youth who are actively searching for work and youth who have become discouraged from seeking employment.
