Could you have a census taker at your door yearly even monthly (While they don’t say anything about monthly visits on their site I have heard that it could be monthly)? Yes you could. Sounds crazy right? Sad thing it isn’t. It’s called the American Community Survey. You can view it at the Census’s own Website here. What do they ask? You can view a general list here. You can view the full list of housing questions here. Population questions here. According to the website you must answer all the questions by law. If you don’t you are fined $100. This is based on Title 13 U.S.C. Section 221. which was passed in Jan 2011.
