The word urban underlies a basic theme. One that its population size is larger than its rural counterpart, two that its size is definitely larger and three that its functions are varied. Function is probably the most important criterion to define a town. The other criteria are population size and population density. Different countries have different parameters to explain an urban space. India has one too.

In India, the criteria for identifying urban places kept changing with time. The frequent changes in the criteria reflected the basic problem of identifying urban places and the issue could not be settled till 1981.

In India, urban areas are given different administrative status by different state governments. The conferring of this status depends on the state-level Municipal and Local Bodies Acts. A place has to satisfy all the three Census criteria in order to be designated as an urban place even if the requirements are criticised by some to be vague, rigid and conservative.

At present, we have 35 million cities (2001 census) in India and 27.8 percent of our people live in the towns and cities.

Many eminent scholars have studied the intricacies of a city and have proposed some unique findings. It was J. Gottman who first coined the term Megalopolis. This city was envisaged to have a population size over 35 million people. G. Sjoberg in his book ‘The Pre-Industrial City’ examined the structure of urban settlements both in Europe and elsewhere in the world, prior to the impact of large-scale industrialization. Then there were many more like Harvey, Peet, Pred etc. who went to make our understanding of cities more lucid.

Building a city isn’t an easy job. The site factors have to be taken into account so that the city is provided with its basic amenities. Then comes several others factors that depend upon what the city’s basic function is to be.
