As of the autumn of 2013 only the most basic data on religious identity from the 2011 census are available and it is not yet possible to explore the correlations (for example, place of birth and religion) that would help explain changes since 2001. The 2011 census asked only for current religious identity. Dropping the ‘religion of upbringing’ question means that some reasons for changes are obscured. It also means that even when all the data is released we will not be able to address questions (such as the links between religion and social mobility) where how people were raised may be more important than what they became possibly half a century later. A further problem is that a small but vital part of the 2001 data – the ‘Other religion’ and ‘No religion’ categories – has been recoded so that some responses which were then coded as ‘Other religion’ have now been shifted to the ‘No religion’ set. A final reason for not replacing the 2001 figures in the text with those for 2011 is that the 2001 census coincided with an edition of the national Scottish Social Attitudes Survey and a large survey of Glasgow, both of which were concerned primarily with religion and supposed associated characteristics. The three sources together allow for considerable depth of analysis and adding the 2011 census figures would have made parts of them even more complex than they are now.
