Marginal seat

A marginal seat or swing seat is a constituency held with a small majority in a legislative election, generally one conducted under a single-winner voting system. In Canada, they may be known as target ridings.[1] The opposite is a safe seat. The term ultra-marginal seat refers to a constituency with a majority of single digits, usually within a percentage of 2%.[2]

Examples of traditionally marginal seats in the United Kingdom include Broxtowe, Watford, Bolton West and Thurrock. In Australia, marginal seats include Lindsay in New South Wales, Bass in Tasmania, Longman in Queensland and Corangamite in Victoria. Ultra-marginal seats in Australia include the federal seat of Gilmore in New South Wales and the state seats of Bundaberg in Queensland and Kogarah in New South Wales.
