This new tradition of modernization is prompting people to leave their homes and to get exposure to the world. As everything comes naturally with positive and negative impacts, one wants to see how this big change is affecting our world. Asia, in particular is the most affecting continent where one can see the rapid growth of urbanization. This paper examines various aspects of urbanization in Asia region and taking Pakistan as prototype of urbanization phenomena.
