They keep calling and leaving notes on my door. They claim by law I have to fill it out. However nothing by certified mail with my name on has shown up saying that I must do it. They should already know who lives here, our ages, and our social security numbers as I do file taxes. I spoke with an attorney acquaintance of mine and he said I do not have to respond to letters or phone calls. However if legal papers come with my name on them then I need to reply. These census people even call me on some of my renters who have not completed the form. They asked the ages and numbers of people living there. I told them I cannot give out the information they requested. They then said I would need to call them and tell them they must complete the forms. I told the census lady I would not be making any calls. Maybe I should just comply but I hate the government and all that goes with it.
