West Bengal Municipal Act, 1993 specifies a set of criteria for the constitution of new
municipal area. Such criteria are, however, subject to
relaxation for constitution of Notified Area Authorities.
The criteria are:
Population of the area should not be less than 30,000.
Density of the population should not be less than 750 inhabitants per square kilometre of area.
One half of the adult population should be chiefly engaged in pursuits other than agriculture, and
Income from taxation and other sources should likely to be adequate for the discharge of municipal functions under the Municipal Act.
