The last census I just ignored the same survey. They kept sending different people to my house, I wouldn’t answer the door. One Saturday one of these ladies approached me while I was doing yard work in the front. I just pretended she didn’t exist; they had no training on how to deal with someone who wouldn’t even acknowledge their existence.
ROFL!! Excellent!
In depth in-person interview, with follow-up calls.
I also remember them complaining that a Census call center was bugging them after 9PM on a Sunday night.
We they told me, I told them that I think ACORN got a contract to do that. Having some knowledge of call centers, I'm guessing that at best, they didn't flag the time zone, and at worst, didn't care.
