The bar graph delineates the proportion of inhabitants residing in metropolises across the globe and various continents.
From a general perspective, it is evident that there has been a gradual increase in the urban population worldwide, with Asia and Africa showing the most significant growth. Conversely, Europe and North America have seen a relatively stable trend.
In detail, the global urban population in 1950 was approximately 30%, which more than doubled to around 70% by 2007. This trend is predicted to continue, reaching nearly 80% by 2050. The urban population in Asia and Africa mirrored this global trend, with an increase from just over 20% in 1950 to almost 60% in 2007, and it is projected to reach nearly 70% by 2050.
On the other hand, the percentage of urban dwellers in Europe and North America has remained relatively constant, with a slight increase from 1950 to 2007, and it is expected to remain stable at around 80% until 2050. This suggests that urbanisation in these continents had occurred earlier, and is now at a saturation point.
