The Christian population of London has declined to 49% from 61% 10 years ago. This means that a little under 4.2 million people describe themselves as Christian.
London is the only region in the UK where fewer than 50% define themselves as Christian.
Despite this decline in Christianity London remains the most religious region of the UK when all religions are included, as previously reported by Urbs.
Data from the Office for National Statistics shows that Christians are quite evenly spread throughout the capital. The outer borough of Bexley has the highest proportion. The lowest rate is in Tower Hamlets, which has the highest proportion of Muslims in the capital.
