(1) The Election Commission of India formed constituencies for Lok Sabha and Legislative Assembly.
(2) The Election Commission had decided upon the constituencies before the first election. As the years passed, there was a lot of migration of the people for business and other activities from the villages to cities.
(3) This changed the demography to large extent. Number of voters in some constituencies reduced while in some it increased to a very great extent. This disturbed the ratio of- seats allotted as compared to population in those constituencies.
(4) Hence, the need to readjust the constituencies arose. The Delimitation Commission of the election commission does the work of reorganising or restructuring of constituencies.
