Swing in United Kingdom

Uniform national swing Meaning in Politics

Description of Uniform national swing published by Mona Chalabi: This is a type of calculation that has been used for decades to predict how a party’s share of the national vote will translate into the number of seats it will have in the House of Commons. It’s now considered quite dated and quite useless. See, swing assumes that changes will be consistent in each constituency, but the actual dynamics of each electoral district can vary a lot. With better constituency-level data, election forecasters have become less reliant on uniform swing.
