I'm doing a paper on Cardiff. Can you teach me about it? 
 That's all I need right now. Thanks! 
 You're welcome! 
 66.9% of Cardiff's people describe themselves as Christian (2001 census) which was a percentage point below both the Welsh and UK averages. 
 Thanks. What else can you tell me about its demographics?
