How are people identified in a census - I've forgotten? Is it just by
name or does each person in a household have to give a unique ID such as
National Insurance number? If they gave NI number, it would make it much
easier for genealogists to trace the correct John Smith as he moves from
house to house between one census and the next.

I've heard it said that most Americans (land of the free) know their
social security number. I've always thought that the NI number had some
merits as a potentially unique identifier. There are places that use it
as your login ID on the computer system.
