this is the voa special english development report.

soon, more of us will be living in cities than in rural areas. population experts at the united nations had thought that would happen by this year. lately their estimate is that in two thousand eight, for the first time in history, more than half of the world population will be in urban areas.

united nations report on world population

the united nations population fund just released its yearly "state of world population" report. researchers say three-and-a-third billion people will be living in urban areas next year. by two thousand thirty, the estimate is almost five billion. the fastest growth will be in asia and africa.
