The given bar chart provides information about the proportion of population living in cities in six different areas in 1975 and 2020, with a prediction for 2050. Overall, it is clear that the percentage of population is increased in all the regions and will continue to grow, although in the various areas this index grow differently.
From 1975 to 2050, urbanisation increased from under 40% to 56% and will grow to under 70% by 2050. Africa and Asia recorded the lowest population in urban areas over the period and in 1975 made up of around a quarter and showed the same index. In 2020, this number reached to 45% and 50% respectively. By 2050, this figure will go up by 15%, but will still remain the least urbanised.
In comparison, regions like North and Latin America, Europe displayed the highest scale urbanisation and continue to grow in the future, but slightly. In 1975, around 65% people in Europe and 75% people in North America lived in towns and by 2020 this mark had gone by roughly 10%. A forecast for 2050, means that North America will remain the most urbanised region and will reach around 90%. Latin America was the lowest urbanised region between these three regions in 1975 and made up only 60%, albeit a projection for 2050 shows that the population in cities in Latin America overtake Europe and will reach 87%.
Oceania, remained stable over the period and expected to rise by 2050, maintaining an average of around 70%.
