I answered number, sex, age - the rest I answered: “I prefer not to answer”
I received the short form. I went ahead and answered after reading the questions and deeming them relatively unintrusive. I would have had some serious problems with the “Community Survey” long form, however. You know, questions like “How many colon polyps do you get in a year?” and so on.
The question about whether I owned a home free and clear, or had a mortgage, was the most obnoxious one, but I figured, what would they do, drown me in a blizzard of Fannie Mae solicitations?
