Today's theme in English class is megacities. First of all, what is a megacity? To become a megacity, there has to be more than 10 million inhabitants. In our English book, that we use in class, there is a text about megacities including a quote by Kofi Annan who where the UN secretary-general. Kofi Annan speaks about the problem about people moving from the country and into the cities. The rural population is decreasing while the urban population is increasing. Cities are having challenges accommodating new inhabitants.
Beneath the quote there are three statics. The first one is illustrating the percentage of the growth of the urban population . As we can read from these diagrams, in 1800 there was a growth of 2% which have increased to 47% percent in 2000. The diagram is also foreseeing the percent in 2015 and 2030. In 2015 it's foreseen that the percent of urban population growth in the world has increased to 52% while it's 60 percent in 2030. That's a huge increase.
In the next diagram we're shown the statics of the rural and urban population percent in different regions in the world. We can see the population statics in 1995 and 2015, a twenty year difference. As we can read from this diagram, the region with the widest rural population is Asia with 2249 million people in 1995 and it's foreseen that this will increase to 2380 in 2015. In 1995 they had an urban population corresponding 1180 million people and 1970 by 2015. As we can see, both the urban and rural population is foreseen to increase. After Asia with the largest rural population there is Africa, and then Europe. In Europe the urban population were 518 million people in 1995 and foreseen to increase to 532 million in 2015, while the rural population which were 209 million will decrease to 188 million people. After Europe there is South America and on top, with the lowest rural population, and urban population matching Africa's there is North America. In 1995 the rural population were only containing of 67 million people and the urban had 231 million people(Africa: 247mill.) In 2015 it's foreseen for the rural population to have decreased to 59 million and the urban to have increased to 301 million people.
What we can see from this diagram is that the rural population in the developing countries is increasing as well as the urban is, while in Europe and America the urban population is increasing and the rural decreases.
This is of course a global challenge because the developing countries has the biggest population increase and then will get, as Kofi Annan said, problems hosting their new habitants, both immigrants and natives.
The third static is showing a rank of the world's biggest megacities. The three biggest cities is Tokyo with 33.4 million people, New York with 24.1 million and Mexico City with 21.7 million people.
