I don't think putting a citizenship question on the census is a good idea. I worked for the census in 2010 when I was between jobs. Considering the community where I canvassed I undoubtedly spoke to illegal aliens, or at least households where illegals were living, even if the person at the door was not. On more than one occasion, I made it a point to mention that there were no questions about citizenship status on the census. As a low paid census taker I was not about to jeopardize my safety. Census takers are not ICE. And many illegals may very well be desperate enough to do something stupid.
