I am surprised that happened more than ten years ago because, from having done research myself, I know it is almost impossible to compare like for like between the two censuses. Ongoing work needs to be done and it needs to be prioritised by the Government such that we all pull together in trying to enable the CSO to work with NISRA in that way. There is an added complication in that the statistics for the North are difficult because they are often not regionalised and there is more of a whole-of-the-UK approach. What agreement could there be between Great Britain, the North and the South to get that on a more level playing field in order that there will be more like-for-like comparisons and better congruence? Is that something we can look at or push in a way that is not ad hoc but more regularised, with a framework for continuous working relationships?
