Answer 2

I did find a few things for you:

1)World Population Becomes More Urban Than Rural

http://news.ncsu.edu/releases/2007/may/1...

Working with United Nations estimates that predict the world will be 51.3 percent urban by 2010, the researchers projected the May 23, 2007, transition day based on the average daily rural and urban population increases from 2005 to 2010. On that day, a predicted global urban population of 3,303,992,253 will exceed that of 3,303,866,404 rural people.  

2)UN says half the world's population will live in urban areas by end of 2008

http://www.iht.com/articles/ap/2008/02/2...

... She said more than 70 percent of the population in Europe, North America, and many other richer developed countries already live in urban areas.

But only 39 percent of Africans and 41 percent of Asians lived in urban areas last year ...

... "During 2008, for the first time in history, the proportion of the population living in urban areas will reach 50 percent,"...

3)Urban population trends

http://www.peopleandplanet.net/doc.php?i...

Thus, whereas in 1950, 30 per cent of the world population lived in urban areas, by 2000 the proportion of urban dwellers had risen to 47 per cent and is expected to reach 60 per cent by 2030. The number of urban dwellers will for the first time have overtaken the number of rural dwellers in the world in 2008.
