Urban Local Bodies (ULBs) of India are the constitutionally provided administrative units that provide basic infrastructure and services in cities and towns. According to Census of India 1991, there are 3255 ULBs in the country classified into four major categories:
Large urban areas are governed by nagar nigams, often simply called corporations. The area under a corporation is further divided up into wards. Individual wards or collections of wards within a corporation sometimes have their own administrative body known as ward committees.
Smaller urban areas are governed by nagar palika, which are often referred to simply as municipalities. Municipalities are also divided into wards, which may be grouped together into ward councils. One or more representatives are elected to represent each ward.
