That's what I did, you can expect that you will get a visit from a door to door canvasser. They will try to convince you that you must fill it all out in detail. You tell them to "get lost" and then they tell you there is a $250 fine for noncompliance (which is BS). they may come back two or three times, stick to your guns and they stop at three revisits. I know that is what happened ten years ago as I worked the 2000 Census and there was a lot of noncompliance back then as well.
I made a copy of section 1, article 2, paragraph 3 of the U S Constitution which authorizes an "enumeration" (a numerical count) of all free citizens and nothing more. I enclosed that with the form and said "sorry, that's all you get".
I expect that someone will come calling while I am "cleaning my shotgun".

PS Or you can avoid them by not answering the door, depends on how far you want to push them.
But back then there was no Obamao.
Things have ‘changed’ and all ‘hope’ is gone. IMO
