It's pretty clear that it's a substantially longer document than the 1966 document. I can table them for the committee to look at.
I notice that in the second clause of your bill you say:
(5) In this section, the term “long-form census questionnaire” refers to a census questionnaire that conforms substantially, in length and substantive scope, to the long-form census used to take the census in 1971...
Why did you choose 1971 and not the more recent long-form census of 2006, for example?
