Megatrends: Demographic Change & Urbanization
The megatrends “demographic change” and “urbanization” will bring even greater challenges in the future. The population will grow from today 7,6 to almost 10 billion people in 2050. 70 % of them will live in cities.
While in Europe, America and Oceania the population will remain almost the same, it will increase rapidly in Asia and Africa. By 2100, Asia and Africa will account for over 80% of the world’s population.
This also leads to a change in the megacities. Today, the world’s largest cities are in America and Asia, and in the future they will be in Africa and Asia. The following graph shows the megacities today (green) and in 2100 (yellow). Most of these cities will be located in Africa and much larger than today’s megacities.
