The “Easiest” Seats

How to win a Parliamentary Election in Sri Lanka

Parliamentary Elections in Sri Lanka follow a Proportional Representation system. Hence, ideally, the number of seats a party holds in parliament should be proportional to the number of votes it wins.

However, in practice, seats are not proportional votes for the following reasons:

  • Bonus Seat: The winning party in each Electoral District gets one bonus seat.
  • 5% Rule: Any party getting less than 5% of the votes in a District does not qualify for seats.
  • Province Seats: Of the 196 seats allocated to districts, 160 are allocated proportionally, and the remaining 36 are allocated 4 each per province. Hence, districts in smaller provinces are favored over bigger ones.
  • Rounding errors

I discuss this in greater detail in (Not so) Proportional Representation.

Hence, some seats need fewer votes than other seats. This is what I mean by “Easiest”. Or what seats required the fewest number of votes?4

The List

Here is a list of the Sri Lankan Parliament’s 225 seats, based on 1,000,000 Monte-Carlo simulations of hypothetical elections.

It assumes the seat allocation to districts in the last (2020) Parliamentary Election.

The number of votes listed is the median cumulative number of votes in scenarios where the said seat was won.
