- Currently, more than \(50\)% of the world’s population lives in urban areas.
- It is expected to have about\(70\)% of the world’s population live in urban areas by \(2050\).
- Over\( 3/5th \)or 60% of the land projected to become urban by \(2030 \)is yet to be built.
- Africa is likely to reach a 50% urbanisation rate only in \(2035\).
- In \(1970\), Tokyo and New York were the only megacities. But today, there are 23 megacities, 13 in Asia, 4 in Latin America, and 2 each in Africa, Europe and Northern America.
- Megacities account for a small but increasing proportion of the world urban population: 9.9% in \(2011 \)and 13.6% in \(2025\).
- Over half (50%) of the urban population lives and will continue to live in small urban centres with a population of less than half a million.
- In 2011, Northern America experienced the highest level of urbanisation (\(82.2\) per cent), followed by Latin America and the Caribbean (\(79.1 \)per cent).
- Africa and Asia are expected to have the highest rate of urbanisation in the coming decades.
- The urban population is likely to treble in Africa and increase by 1.7 times in Asia over the next four decades.
- Between 2018 and 2050, just 3 countries – India, China and Nigeria – together are expected to account for 35% of the growth in the urban population of the world.
