The line graph illustrates how many people reside in urban areas in four countries namely The USA, Korea, China, and India since 1970, along with projections until the year 2030.
Overall, there are increases in the proportion of residents who lived in urban areas in the four countries examined, with the most significant rises being seen in the figures for Korea and China. It is also clear that the urban population in the USA is consistently the highest throughout the period.
The percentage of urban residents in the USA was by far the highest, at 70% in 1970, after which it saw a gradual rise to under 90% in 2020, and will be predicted to increase slightly to exactly 90% in 2030. Similarly, the share of Korean people living in the cities began at 40% in the first year, followed by a substantial growth to 98% after 50 years, and a projection of slower growth to the same amount as the USA (90%) by the end of the period.
Meanwhile, the proportion of urban inhabitants in China stayed unchanged at 20% in the first 20 years, with a subsequent sharp increase to nearly 60% in 2010, and a final prediction of slight rise to 65% in 2030. A similar change, but to a lesser extent, can be seen in the figure for India, remaining stable at 20% for the first decade, after rising considerably to over 30% in 1992, it is expected to experience a steady growth to 37% in the final year.
