Irreligion in the United Kingdom has a history going back to approximately the 1700's, when the rejection of Christianity was first developed as a philosophical position. Irreligion is more prevalent in the UK than in other parts of Europe, with the term "secularism" first used in the mid-19th century. In 2021, the United Kingdom census showed less than half of the population declared themselves to be Christians in England and Wales, with those identifying as having "no religion" being the fastest-growing group. This has led to British institutions and legislative stuctures being criticised as increasingly unrepresentative of what is becoming a largely non-religious population.
