The line chart below illustrates the trend of global population growth in millions from 1800 to 2100, while the bar chart details the distribution of this population in developed and developing regions between 2015 and 2040.
Overall, the world’s population has significantly increased until 2040, at which point it is projected that it will stabilize and moderately declined by the end of the period. Furthermore, each decade, residents in developing nations have consistently risen and it is predicted to continue rising.
At the beginning of the period in 1800, the global population stood at only around one billion, with a marginal increase to approximately 2 billion by 1920. From 1940 onwards, however, it rose dramatically, surpassing 7 billion by the early 21st century. Looking ahead, the population is projected to continue rising, peaking at around 10.5 billion near 2080 before gradually declining to roughly 10 billion by 2100.
In the year 2015, developing nations have a larger populations compared to developed ones, approximately 2.1 billion and 1 billion respectively. Approaching the present, growing regions’ population has consistently increased and is about to reach 3 billion, while less developed areas’ resident remained at 1 billion. Furthermore, in 2040, it is predicted that developing regions’ population will continue rise, reaching 4 billion, while population in developed areas, however, will stay constant.
