First, we must understand the context of the delimitation process as stipulated in the constitution.  Some key principles of delimitation (as per 13th schedule):

  • -Constituencies should be delimited without crossing state boundaries
  • -To take consideration of existing administrative facilities for the establishment of necessary registration and polling machines
  • -Number of electors within each constituency in a State ought to be approximately equal (exception is given for districts with rural disadvantage)
  • -Maintenance to local ties
  • -Number of electors shall be taken to be as shown on the current electoral rolls

A you can see the map above, the large number of red and blue bubbles indicate there is a very big discrepancy in the value of voter between the urban and rural electors. This is in contrary to the spirit of Federal Constitution.


The histogram above shows the variation of total number of  electors  from one state constituency to another. EQ is the Electoral Quotient and it represents the ideal number of electors per constituency. Hence, your  voting value can differ in varying amount with your neighbour’s.


1/3 of the electors can select half the seats. Is that fair?
