Future world population
The graph shows the three possible results for the future of world population growth from 2000 to 2050. It tells us what will mostly going to happen by 2050 we have high, medium or low fertility rates.
If the world wide kept going on high fertility rate of 2.5 children per women, we can say that population of almost 11 billion. The rate in India is 2.72 and this is very high and up to 1 billion. On other hand, Arab countries rate is high for example in the UAE its 2.42 and in Egypt is 2.66. However, if we have countries with medium fertility rate as in USA, the world rate will be 8.9 billion by 2050. With low fertility countries such as Europe and Japan, the world figure in 2050 will be about 7.3 billion.
In conclusion, if this some of high fertile counties will stay at the same rate we will see a world population more than 10 billion by 2050and is it was like low fertility countries we will see a population of around 7 billion.
