I understand the reason behind a census (required for determining proper representation), however there is some information that is not necessary for the purpose in which it was originally intended.
The video was annoying because he kept using the words "no answer" listing each of his questions.
By the way, you do not have to give the Census taker any information at all if they come to your door. You do not have to open the door at all, to my knowledge. They do not have the authority to force that, not to obtain any of the information other than number in household. So, really... I'm not sure why this guy is so upset. If it's not required by law then why is he so angry?????????????????
