The rapid and sustained increase in the number of young people in the global south is one of today’s most significant demographic trends. Around 90 percent of young people reside in developing countries (Shankar 2010).
By 2030 Africa is projected to have as many youth as East Asia and by 2050 could also exceed the youth population in South Asia (Garcia and Fares, 2008). Young people make up approximately 30 percent of the total population in African countries, and this is increasing fast (Panday 2006).
Growing numbers of young people entail a process of demographic change within societies; ‘rejuvenation’ in a literal sense. Thus, in 2005, 76 percent of the Zambian population were under 30 years of age, with those between 20 and 29 years accounting for a mere 18 percent.
