Surprised. I expected a Tower Hamlets ward up there.
Tower Hamlets' most heavily Muslim ward (St Dunstans and Stepney Green, 48.7% Muslim) is only no. 41 on the list. Your surprise is due to the fact that even though Tower Hamlets' Muslim population is almost twice that of Bradford's (in percentage terms), Bradford's Muslims are heavily concentrated in a few central-city wards, while the (mostly Bangladeshi) population of Tower Hamlets is spread relatively evenly throughout the borough. Due to white flight and the legacy of post-industrialism, many Northern cities have huge racial, religious and linguistic disparities between homogeneous populations living in very close proximity to each other.
Yes. Also, it's worth remembering that the "City of Bradford Metropolitan District" contains a lot of areas no-one really thinks of as part of Bradford: the Muslim population of Bradford proper will be higher than that in the district (even taking Keighley into account).
Someone come up with a reasonable definition of
Bradford, London proper by wards. It might be more Islamic than Tower Hamlets.
