## How the Ballots are Counted: The Simple Way

## STV is a proportional system where voters elect a team of local

and regional MPs using a ranked ballot.

The easiest way to count the ballots is just like the run-off vote that

## political parties use to elect their leaders.

## Voters rank their preferred candidates - as few or as many as they

## wish. The candidate with the fewest first preferences is eliminated

## and those ballots transferred to the next choice on each ballot.

## This is repeated until there are only as many candidates left as

## seats.

In rural ridings electing just one MP, this is also how the votes

## will be counted.

##

## This simple method of using STV - multi-member instant run-off

## voting - produces the same results as the method below with the

## extra steps 97% of the time.

##

## How the votes are usually counted in a multi-member riding:

##

## To get elected to one of the seats on the team, a candidate would

need a certain quota of votes.

## This number needed to get a seat (the quota) will depend on how

many voters there are, and how many seats there are.

You can figure out the quota for your riding by taking the total

## number of ballots cast, divided by the number of MPs to be

## elected plus one, plus an additional one.

##

## So, if there are 100 voters and 4 candidates to be elected, each

## MP would need 21 votes. (100 / 4+1) + 1 = 21). Watch

## the videos above and try STV here..

##

## All you really need to know:

## In a five seat district, a candidate would need about 16% of first-choice votes to be elected, although in some cases the last MP to fill a seat will be elected with less than a full quota (as low as 10%). In a riding with more MPs, that threshold would be lower. In a riding with fewer MPs, that threshold would be higher.

Part Two Below:

From the perspective of the voter, STV is straightforward. Candidates are listed alphabetically on the ballot paper, and voters mark their first choice candidate with the number 1, and then continue to rank other candidates in order of choice (2, 3, 4...).

These preferences are transferred from one candidate to another as

the ballots are counted.

While each voter has one vote, by indicating a ranking of candidates, the voter is

in effect instructing the returning officer what to

do with that vote.

While voters have the option of ranking all candidates on the ballot paper, in practice the average number of preferences indicated is about four.
