The Government Census takers will be knocking on your door in the very near future. The census takers will be armed with a battery of questions they will ask you to answer under penalty of fine if you refuse. While our Constitution allows the Federal government to conduct a census it is limited purely to a head count of people. This was devised so  as to determine the number of representative that could be elected from each state. Nothing More or nothing less. The Federal Government as NO authorization under the constitution to do or ask anything more than that.

Article I Section II of the Constitution

Representatives and direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers, which shall be determined by adding to the whole Number of free Persons, including those bound to Service for a Term of Years, and excluding Indians not taxed, three fifths of all other Persons. The actual Enumeration shall be made within three Years after the first Meeting of the Congress of the United States, and within every subsequent Term of ten Years, in such Manner as they shall by Law direct.
