Africa in 2050: Young & optimistic...with a caveat

Africa, already the world's second most populous continent with more than one billion people, is experiencing a demographic shift unprecedented in it scale and swiftness, according to Generation 2030 Africa, a new report released by Unicef on the continent's child demographics.

Consider this: on current trends, in the next 35 years, 1.8 billion babies will be born in Africa; the continent's under-18 population will increase by two thirds to reach almost one billion; and Africa's overall population will double in size, reaching 2.4 billion.
