That's exactly my problem with it. The questions they ask ARE none of their business. Originally, the census asked your name, where you live, names and ages of all family members or people living in your home. If you go into genealogy, you see that even back in the 1800s, the people didn't give out all the information that was asked. We filled it out, but only to keep them from coming to our door. And I heard, not sure it's true, that they'll go to your neighbor's house and ask questions about you. THAT would REALLY tick me off!
