how many cities in the world
There are about 27,000 places in the U.S. and 304 million people. Based on a world population of 6.7 billion, there are close to 600,000 cities, towns, villages, hamlets etc. in the world. There are 650,000 villages (towns and cities included) in India for a polulation of 1billion+. That is a sixth of world population. On the same scale, there should be 6 X 650,000 = 3,900,000 villages, towns and cities in world. The earth is not a mathematical problem.
