Welcome to "Cities of Today, Cities of Tomorrow!" The Cities project is an interactive programme brought to you by the United Nations CyberSchoolBus. Its six intense units of clear writing, exciting information and great images give you the best overview of urbanization-its history, its potential, its problems... You can focus on just one part of the curriculum-say, the profiles of major cities, or an activity on population density-or you can take all 6 units as a whole. Just make sure you enjoy it all.
The world's urban population is currently
growing at four times the rate of the rural population.
