I must say that I am underwhelmed by the census. It's probably because many of us who are of a certain age know where everyone was, etc. and the 1911, 1939, subsequent deaths, marriages and births are already collected. I'll store them for my records to pass on but ....
Sadly, this is the last UK census that I'll see as the 1951 is probably too late, unless I live to be into my 100s.
PS - to me, the 1911 was far more informative.
