The two graphs illustrate how urban and rural populations from less developed and more developed regions changed from 1950 to 2010, with projections until 2050.
Overall, the urban population from both regions tends to increase, while the rural population from both regions tends to decrease over time.
Firstly, the urban and rural populations from less developed regions saw different changes. The urban population experienced noticeable changes, rising from 500 million in 1950 to 1100 million in 1990, then slightly went up in pace, reaching 2500 million in 2010, while the rural population surged at a moderate and continuous pace from 1200 million in 1950 to 300 million in 2010. In the future, it is expected that the urban population will surge at the same pace and reach 5000 million in 2050, while the rural population will slightly decrease down to 2800 million.
Secondly, the urban and rural populations from more developed regions experienced moderate changes. The urban population climbed at a minimal pace from 490 million in 1950 to 1 billion in 2010, while the rural population saw a slight continuous reduction, going down from 490 million in 1950 to 250 million in 2010. In future years, the urban population is going to rise, peaking at 1.25 billion in 2050, while the rural population is expected to continue the pace, reaching 200 million in 2050.
