You probably received in the mail a first notice from the Census Bureau, demanding that you complete an online questionnaire. I ignored that one, and received a follow-up questionnaire a few days later, which I will also ignore. But I did take the time to annotate the second notice for your amusement:
This is in keeping with my non-compliance with the desires of the census snoops in 2000 and 2010, as I relate here and here. The reason for my non-compliance is given in the post at the first link:
[T]he Constitution mandates the census, for the purpose of apportioning membership in the House of Representatives among the States. And it says in the Constitution that “the actual Enumeration . . . shall be made . . . in such Manner as they shall by Law direct.” But the operative word is “enumeration.” It follows that Congress’s power to direct the “manner” of the enumeration is restricted to such matters as when and at what cost the enumeration shall be made.
The census form (even the short one) has long since become intrusive and vastly overblown in relation to the constitutional purpose of the census. Now, as in 2000 and 2010, I refuse to violate the Constitution.
