I would have thought census activity wasn’t expected for another five years.
We only answered two or three of our questions this past census and we never had a follow up letter or visit.
From what I’ve read, they have nothing to back gathering more than the most basic “number of residents” questions. If they kept showing up, I’d smile and say, “sue me.” There no authority for personal questions by any census worker and you’ll find no one ever gets fined.
We filled out and only answered the 2 or 3 also They sent someone out and I told them I had answered on the form and they left. No one followed up. I would have told them the same thing, anyway.
