the graph below shows the percentage of population in cities since 1970s with projections to 2030

The line graph illustrates the changes in the urban population in four countries in the 1970s with projections to 2030. As transparent from the statistics, the four countries exhibit an upswing trend during the 4-decade period [starting from = commencing] 1970, and the projected figures are upward over the remaining

years

.

Also

noteworthy is the fact that the urban population of the USA and

Korea

significantly dwarfed that of the remaining countries. In 1970, the percentage of urbanists in the USA was [ a big figure of = a staggering] 70%, being 30% higher than the figure for

Korea

. The following 40

years

witnessed a substantial rise in the USA’s urban population, [increasing to = jumping to] 90%. The same but more dramatic pattern took place in

Korea

in which the figure rocketed to 85%, narrowing the gap between the two nations. The percentage of city dwellers in China and India sustained a period of stability for 20

years

and 10

years

, respectively. By 2010, the former had undergone a sharp increase to 60%

while

the latter rose gradually but slightly to reach 35%. By 2030, the proportion of citizens dwelling in cities in

Korea

is predicted to equal that of the USA at 90%.

By contrast

, there will be a moderate rise of 5% in the percentage of those city inhabitants in China and India.
