How they going to know I am answering wrong? Oh wait, they can check such with the IRS. Oh double wait, why the frak am I filling out a census then if they can get what they need to know from their IRS databases? =.=
Because the people they really want to count are not in the IRS database. The welfare scum pay no taxes, but can be counted upon to vote for the Democrats and their welfare plantations that they have replaced our cities with.
They are counting illegals, too. It is very important to them that the illegals participate in the census count.
