In the 2001 United Kingdom Census, 71.6% of people in the UK described themselves as Christians, but only about 15% of these said they belonged to, or were active members of, a church.

That leaves a large number of people who identify themselves as Christian who aren't active members of a particular church. The Open University is interested in finding out what Christianity means to these 'missing' Christians - and, if you're one, we'd love to hear your views.

Please take a few minutes to fill out our online survey - your responses will be totally anonymous and help build a clearer picture of what faith means in modern Britain.
