Megacities
Examine the consequences of megacity growth for individuals and societies
2007 was the first year in human history when more than 50% of the world's population lived in urban areas. Urbanisation is happening at a faster rate than at any time in human history.
Asia accounts for over half of today's megacities. By 2030 nearly 9% of the world's population will live in 41 megacities, with India and China having 7 megacities each.
It is predicted that Africa will have some of the highest rates of urbanisation in the future. While European and North American megacities show limited growth, megacities in developing economies continue to grow rapidly.
