If I'm not mistaken, I believe the censuses in 1971 and 1966 were both public documents, but we would have no problem tabling a copy of them.
The 1966 long-form census that we have here is two pages long. The back page--just for clarification, the second page--is for names five through ten, so it would only apply to families who had more than four members. It's a letter-size sheet. In 1996, if you have a family of four, you can fill out the entire census on the front page—what you referred to as the long-form census.
I would say that there was a substantial difference between the long-form census in 1971 and what Ms. Bennett referred to as the long-form census that only existed prior to 1966.
In terms of your bill, I want to ask questions--
