In this vent, are you truly required by law to respond? Oh yeah, just like the Census. As they note:
Yes. You are legally obligated to answer all the questions, as accurately as you can.I suppose you can argue that you only want to obey the laws you like. Then again, how can you dislike us knowing as much about ourselves as is possible? The data are all made public, for crying out loud. It's not as if they're collecting secret data on you, though I suppose for some folks they also see black helicopters flying around their house at night.
The relevant laws are Title 18 U.S.C Section 3571 and Section 3559, which amends Title 13 U.S.C. Section 221.
Your answers are important. As part of a sample, you represent many other people. Find out how each question helps your community, your state, and the federal government in questions in the form and why we ask.
