The Scottish National Party completely botched Scotland’s census, and it did so because of its ideological obsession with diverging from the rest of the United Kingdom. It will therefore be more difficult to plan for the delivery of public services. National Records of Scotland says that lessons will be learned from this fiasco. Surely there is one main lesson to learn, which is that, in 2031, the census should be UK-wide. Will it be? I am looking for a yes or a no.
