This paper, part of the Open Left project at Demos, aims to set out a picture of the country that will go to the polls this year. This forms a core part of Open Left’s aim to renew the ideas and agenda of the centre-Left, over a decade after Labour was first elected. The paper considers the ways in which the British electorate has changed over the last two decades and the potential political implications of these changes. While it would be an overstatement to claim that Britain is a fundamentally different country demographically compared to the early 1990s, there have been important shifts. The British electorate is older, better educated and more diverse. Its class, occupational and household structure is more complex. There is every indication that these changes will continue in the coming years.
