Since reaching a peak of 2,2% in 1962/63, the growth rate of the human population has decreased worldwide
In 2009 the estimated annual growth rate was 1.1%
The world population will reach as estimated 9,1 billion in 2050
The growth rate in less developed countries is higher than in more developed countries, therefore almost all of the estimated growth by 2050 will take place in less developed countries
With a growth rate of about 0,1% in more developed countries, the population figures will show little growth over the next 40 years and remain stable
Worldwide the fertility rate is decreasing, with the more developed countries nearing the replacement level (2 parents, 2 children to replace them) while the figures in less developed countries are still significantly higher
