The average age in sub-Sahara Africa is still under 20.

The average age in sub-saharan Africa is still under 20 - that's compared to 40 in the UK or 48 in Japan. And the number of young people in Africa is growing as the population continues to rise. So what could all this mean for the continent? That's the topic of this week's BBC Africa Debate. Will Africa's young population drive growth and bring about change - or could it be a problem to have so many young people, without enough work? Tell us what it is like to be young where you are?
