How does Vote Match work?

Vote Match is based on StemWijzer, developed by the Institute for Political Participation in the Netherlands. Vote Match is the official UK Partner of StemWijzer.

Choosing the statements

We identify what the top issues in the election are using polling data and advice from academics and experts. We then look at the parties’ policies and draft statements which distinguish between them. Every statement aims to have at least one party who agrees and one who disagrees.

Getting the parties to answer

All our information on party positions comes from the parties themselves. We fill out draft answers for the parties using publicly available material: speeches, policy statements and manifestos. We then give parties the opportunity to check our answers to make sure they reflect current party policy. If parties do not wish to participate, we use the draft answers instead.

Calculating the party match

Vote Match compares your responses to the statements with the responses of each of the parties to find out which party you are closest to on the issues that matter to you.

  • For each statement in which you and the party agree (e.g. you both either agree, disagree or are open minded about a statement), you score 0

  • For each statement in which and the party completely disagree (e.g. you agree and the candidate disagrees, or vice versa), you score 2

  • For each statement in which you partly disagree (either you or the party is open minded and the other either agrees or disagrees), you score 1

  • If you skip a statement, it is ignored and not included in the calculation

  • Statements which you choose as very important count double; statements which you choose as not important count half as much

This gives you a score which represents how much you disagreed with a party. This is subtracted from the maximum possible difference between you and the parties, which depends on the number of statements you skip and the number of issues you rank as important or unimportant, to give you a score which shows you how much you agree with a party.
