Where is the world's most "godless" city?

As sociology professor Phil Zuckerman pointed out in an essay in The Cambridge Companion to Atheism, even the terminology of religious belief can throw up roadblocks to understanding. If my idea of religious practice is a good deal looser than yours, can we have a meaningful conversation about which cities are godless and which are not?

Naturally, the methodological hurdles have not prevented researchers from making the leap. According to the 2011 Census of England and Wales, Norwich had the highest proportion of respondents reporting “no religion”. The city’s figure was 42.5% compared with 25.1% for England and Wales as a whole.

The survey revealed that Brighton & Hove came in a close second in the ‘godless’ stakes with 42.4% of residents describing themselves as having no religion. Local newspaper reports in both areas pointed to the relative youth of the population and the high number of students as being relevant factors. If you are young and bright, it seems, you are more likely to be irreligious.
