An urban area is defined as an area with a population of more than 5000, a density of more than 400 persons per square kilometer, and with 75 per cent of its male workers engaged in non-agricultural profession. State governments have flexibility in defining urban areas for administrative purposes. It is not possible to give a precise figure of the degree of urbanization in the world, due to different definitions of the level of urbanization used by countries. However, what can be said with certainty is that the world will get increasingly urbanized, as most new manufacture and investment will take place in urban areas. In this paper we want to discuss the urbanization and development.
