The United Kingdom’s Office for National Statistics just released the results of the 2011 census and the results show that nearly 25% of the people in England and Wales profess no religion (PDF) — nearly 14,100,000 people.
Even more striking is the fact that, while the percentage of non-religious people has gone up from 15% in 2001, the percentage of Christians in England and Wales has dropped from 71.8% (2001) to 59.3% (2011):
The New Humanist blog reports that these numbers come despite a poorly-worded question that assumed people were religious to begin with:
The rise in the number of atheists comes in spite of a question widely believed to lead respondents towards selecting a religion instead of the “No religion” option. The Census asks, “What is your religion?”, and secular campaigners argue that this involves an assumption that those responding have a religion. In the run up to the 2011 census the British Humanist Association ran a high profile campaign to raise awareness of the fact that “No religion” can be selected by those with no religious affiliation.
For what it’s worth, the city of Norwich can boast the “highest proportion of the population reporting no religion” at 42.5%.
