Interesting thread. I was just sitting down to look into the whole census malarkey and naturally looked here first ;-)
A few thoughts in no particular order:
I am a sovereign living human. What the hell are you asking me all this crap for and what LAWFUL (as opposed to "legal") reason could you have for wanting it from me? I do not contract with tosspots. I am beyond the stupidity of your small-minded blinkered constructs of who or what you think I am.
Thinkest thou that having a census during a plandemic with a prison mentality (Problem-Reaction-) "Solution" running concurrently is just a coincidence?
If anyone feels the need to fill in the form, remeber that they will usually ask you to state who is in your house on the DAY of the census. Why not get a critical mass of people to all include Dominic Cummings as being present? He does get around during lockdowns after all. LOL. Other candidates would be Martin Bormann, Lord Lucan, Enoch (whom God "took") etc. etc.
Liked Allya's response above. Answer idiots at your door with idiocy in kind. Insist they also keep their social distance if they do call and then claim that you can't hear them as you have poor hearing and have been locked down with a shit load of alcohol and Custard Creams. Ask them if they are Jehovah's Witnesses. If they say no, ask them if they'd like you to show them the way to being one. If they decline your kind offer, suggest a Custard Cream instead. If they ask you to complete it online, tell them your computer has a REAL virus but you can't get a technician to call as they are all locked down because of a make-believe one. You don't own a phone with internet capabilities (absolutely true in my case.... best "sacrifice" I ever made). Ask them continually to speak up and to wear a mask then complain you can't hear them through the mask at distance. If they speak louder, ask them to stop threatenng you simply because you aren't transgendered!
Etc.! Etc.!
