The illustrations show the changes in the global population from 1800 to 2100 and compare the distribution of this population between developed and developing countries for the period 2015 to 2040.

Overall, the graph forecasts that the global population will go up until 2045. The chart indicates that all of the world population growth between now and 2040 is attributed to developing countries. The growth rate in the developed countries is expected to be close to zero.

According to the first graph, in the beginning of the 19th century, the global population stood at just 1000 million. Over the period between 1800 and 1950, there was a slight rise in the world population, while the following 67 years saw a boom, reaching 7000 million. This upward trend is expected to continue till 2045 when the population will reach a peak of over 8000 million. However, the figure is predicted to fall to somewhere in the vicinity of 6000 million by 2100.

On the other hand, around 1200 million people inhabited in developed areas in the 2015s and the projection reveals that this number will remain stable till 2040. By contrast, the population of developing areas will climb gradually from over 2200 million to 4000 million by 2040.
