The graph below shows the percentages of population living in the towns and cities in 4 different countries from 1970 to 2030.

The given line chart illustrates the percentage of the population in the cities among four different nations, namely the USA, South Korea, India and China since 1970, and forecast trends until 2030. Overall, it is salient that there were upward trends in all four countries and they are expected to reach the highest percentages in 2030. More specifically, the USA experienced a stable trend from approximately 75% in 1970 to just over 80% in the estimated 2030, remaining to occupy the first position in the given years. South Korea, on the other hand, saw significant growth in the population from 1970, started at 40% in the beginning, drastically mounted to nearly 80%, and has presented a fairly identical figure with the USA since 2010. Last but equally crucial, it is striking that there is a statistical intersection between India and China at roughly 25% in around 2000. India fluctuates between 20% and 40% over the period given. In stark contrast, however, China observed a slight increase, eventually replacing the proportion of India, being likely to reach 40% in the future.
