The line graph provides the data on the proportion of people who live in cities in four countries, namely the US, South Korea, India, and China, over the period of 60 years between 1970 and 2030.
Overall, it is clear that the percentage of urban population in the US was leading in the past and is predicted to remain the highest among the figures for other countries in the future. Despite increasing slightly at the beginning, the figure for the US remained steady and is expected to stay stable, unlike those for India and China that fluctuated over the given period. Additionally, the share of people residing in urban areas in South Korea witnessed a gradual increase and may level off in the future, coming a close second to the US.
Regarding leading countries, the figure for the US increased from around 75% in 1970 to nearly 80% in 1990, staying constant after. Notably, the share of urban population in this country was the highest in the past and may stay that way for the rest of the given period. As for South Korea, it made up around 40% at the beginning of the period, gradually increasing to just under 80% in 2010 and leveling off afterwards. Additionally, the figure for South Korea came a close second after reaching the period of stability.
As for other countries, in 1970, the proportion of people living in cities in China was slightly lower than that in India, accounting for approximately 20%. Afterwards, both countries experienced an upward trend, with India moderately decreasing after around 1994 until 2010 and China overtaking it as the latter continued to rise. The figure for China is predicted to achieve roughly 40% by 2030, which is almost half the share of urban population in the US and South Korea in the same year, while that for India may be slightly lower.
