APPROACH:
All over the world, there are two known criteria of general representation, namely, territorial or geographical division of constituencies and the functional or occupational basis for composing a constituency.
Territorial Representation
A widely prevalent form of representation in most democratic states is the territorial or geographic composition of constituencies. The total electorate of the country is divided into territorial constituencies, which elect one representative (if a single -member constituency) or more (in the case of the multi-member constituency). The entire population is divided into constituencies with a more or less equal number of voters. After every decade, the constituencies are delimited to accommodate the population change s, under the supervision and control of the delimitation commission established by an act of parliament.
Functional Representation
In this system, the citizens are divided into constituencies on the basis of their economic functions or occupational interests, which they represent in society. For instance, there would be separate constituencies for farmers, Industrial workers, traders, manufacturers, teachers, lawyers, journalists, and government employees. housewives etc.
The underlying assumption is that citizens' representation is more genuinely and directly assured if they are composed in specific functional units for elections, rather than in occupationally varied and functionally heterogeneous territorial units.
Merits of the system of territorial representation:
Limitations of functional representations:
There are several weaknesses in the system of functional representation.
Keeping all this in mind, therefore, the method of territorial representation is preferred in almost all democratic systems. However, the principle of functional representation is sometimes incorporated in the composition of the upper house in bicameral legislation like in the Rajya Sabha in the parliament of India.
