Proportional representation (PR) using the In Place method does not require the use of assigned multiple-member voting districts but uses the current riding districts. These interactive pages may be accessed with the Apple iPad in portrait mode.
Each voter has one vote, which produces a Party Elected List . This is essentially the 'normal' election results. In this method, this initial list will determine which party may get 'added seats'. This is an additional member system.
A party will get onto this list in one of two ways. Either by winning at least one seat, in the first-past-the-post way, or by gaining 1% (this is arbitrary) of the popular vote. For the Canadian election of 2015 the Total Votes of 17,569,634 votes gives the Threshold Votes to be 175,696 for a party to be added to this list. The largest party not on the list is the Libertarian Party with 20% of the Threshold Votes needed.
There is a Navigation Panel that allows the Difference Limit to be varied from -0.00 to a value where no seats are added. Note that the Difference Limit is critical to the number of seats that are added. A value of -0.00% may give the best overall proportional representation, however, or just opt for, say -3.00% , which for each party will decrease, the difference between the %Seats and the %Votes, to within this Difference Limit. To vary this limit, link to one of the two Difference Limit values.
This method produces a Resultant Party Elected List that is now more fully representative of the wishes of the electorate. All voters will be able to more easily have their parliamentary representative advocate for them as they are from their own constituency. All candidates will have a strong link to those who voted for them.
The third list is the Candidate Non-elected List (i.e. not first past the post). This candidate list is sorted in descending order by the number of votes received. For each party, the Difference Limit is used to determine if this candidate will be considered for an added seat in parliament, changing the overall Least Square Index. For each row, the party which is increased, the riding, the candidate votes, the added member as well as the first past the post winner for that riding, will be displayed. There would be only a marginal increase in the number of parties, if at all.
This method requires candidates to be with a party, unless they choose the 'independent' option effectively removing them from this seat increase method. All votes contribute to the election of a candidate so parties need to campaign in all ridings, not just those where they have the most advantage. Aware that each vote can make a difference, voters are more likely to cast their vote.
