Turnout in the 2017 General Election

Why is turnout important?

If turnout is high it means more people have been involved in making the decision about who represents their local area in Parliament, and the person elected will likely be more representative of the people living there.* A high overall turnout also arguably gives greater legitimacy to the result and provides your MP with a mandate to serve.

Turnout can have a big impact on the result. While it is true that some campaigns do better if turnout is low in particular demographics, in other seats the candidates’ votes are very close (see here), and the result is decided by just a handful of voters! So a large turnout across the whole constituency has the potential to swing the vote significantly.

It is also an unfortunate truth that politicians will sometimes look at voter turnout before making key policy decisions. If a certain demographic‘s turnout is high then politicians may be more likely to make policy that benefits that demographic in order to please them and subsequently win their votes or retain their support.
