The charts illustrate the global population growth from 1800 to 2100 and the contribution of urban population across world region.
Overall, it can be seen that the global population rose gradually for more than a century before decreasing sharply at the end of the period. Besides that, urban growth is forecast to grow in developing regions than in developed regions.
Turning to the details, between 1800 and 1900, the global population increased slightly from 1000 millions to under 2000 millions. A rapidly rise began after 1940, with numbers climbing dramatically to 6000 millions by 2000. The figure is predicted to continue increasing, reaching a peak at about 8000 millions in 2050. Then, it fell by 2000 millions in the end of the period.
About urban population, developing regions are accounted to double from just over 2 billion in 2015 to almost 4 billion by 2040. In contrast, developed regions will remain relatively stable at just above 1 billion, with little change over the 25-year period.
