How Christian upbringing divides the religious nones in Britain: exploring the imprints of Christian upbringing in the 2016 EU referendum

Over the last few decades, Britain has witnessed a significant decline in Christian affiliation and the corresponding growth in the number of religiously unaffiliated individuals. Relatively little attention has, however, been paid to 'former Christians' who were brought up in a Christian household but now identify as having no religion. This study focuses on the effects of Christian upbringing on the voting behaviour of religious nones in the EU referendum of 2016. Using data from the 2016 British Social Attitudes survey, the empirical analysis in this article examines the socio-cultural characteristics of Anglican, Catholic, and 'Other Christian' households as well as their role in shaping the voting turnout and the voting intentions of individuals who are religiously unaffiliated. The results suggest that Anglican upbringing and Catholic upbringing serve as salient proxies for national identities among the secular groups. Additionally, in the EU referendum, the voting behaviour of religious nones with different kinds of Christian upbringing was very distinct. This reveals that religious upbringing is a source of within-group variety among British religious nones and that Britain's Christian heritage still has important socio-political implications despite the decrease in the country's Christian population.
