I actually happen to be working for the Census Bureau at the moment, and this guy is a bit out of line. We're limited to 3 phone calls and 3 personal visits before we have to turn the case back in to our crew leader... I would suggest going to the Census Bureau's website and looking up your Local Census Office (LCO) and calling and complaining about him, especially if he happened to leave a Notice of Visit. This type of harassment should cost him his job if his bosses know about it... By the way, for a Census form to be considered 'complete' Only 3 of the following 5 are needed. Name/Age/Ethnicity/Hispanic Origin/Sex.
