Courtesy of StratFor, I found an interesting piece of information.
The world population growth will stall this century, contrary to the ever growing population.
The maths are pretty simple as the reason behind it.
The replenishment level of the population is 2.1 children per woman.
In most of the Western world we are already under it.
In growth countries such as Mexico, Turkey etc we are close to 2.1 and decreasing (by 2040 it will be similar to the West)
In underdeveloped countries as Bangladesh, Bolivia 2.1 will be reached by 2060.
The reason behind is the passage from an agricultural society where children help is economically needed to an industrial society were children are an economical burden.
So the world human population will stall somewhere between the current 7 billions and 9 billions,
Again this will have profound long term implications- beyond the scope of this blog.
