How will the world be different in the 2050-2060 timeframe in terms of wealth and people?
The wealth will double over the next forty years. This will be like the average moving from Romania to Czech Republic. Asia will get close to the per capita levels of Europe today. Asia will still have a broad range of income but Europe currently has a broad range of incomes.
The population will be added in the cities.
The population split would be more like more than doubling Africa and adding half of the population of China in Asia.
We will shift from 7.6 billion people to 9.8 billion in 2050 and 10.2 billion in 2060.
This is an increase of 2.2 billion by 2050 and 2.6 billion by 2060.
The population increase by 2060 is almost like adding another India and China.
However, the population split would be more like more than doubling Africa and adding half of the population of China in Asia.
Asia’s population will go from 4.5 billion now to 4.92 billion in 2050 and 5.2 billion in 2060.
Africa will increase from 1.3 billion now to 2.9 billion in 2060.
The world should get twice as rich by 2060 after adjusting for inflation.
Asia will get four times as rich by 2060.
The world will have gone from 55% urban now to 68% in 2050 and over 70% in 2060.
The world will go from adding 78 million people every year to cities and slow down to 45 million per year. All of the young people and some of the old people will move off of farms and villages and into cities.
The rural population will decrease from 3.4 billion to 3.2 billion in 2050.
There are about 400 million people in megacities now.
There will be almost 900 million in megacities in 2050.
There will be about 1.1 billion in megacities in 2060.
There will be about 2.1 billion in megacities in 2100.
Currently global nominal per capita income is about $11,000 and on a purchasing power parity basis it is $18,000.
The middle countries are countries like Romania.
Doubling income and increasing urbanization means the average countries in the 2050s would be equivalent to the people of Czech Republic, Portugal or Spain of today.
