I suspect that was the annual American Community Survey.
I was selected twice in about four years. I declined to fill it out and had several calls and visits to my home.
There is no reason for the government to ask those questions.
I think we got this once. We just didn’t answer the questions we didn’t like. Never heard from it again.
(Though I may be confusing it with the regular census, which we also goofed with a little.)
