From the first page of the Census:

Yes. Unfortunately, this is in the middle of a long document that strongly resembles the "Terms Of Service" formality which... I dare say most of us routinely scroll to the bottom of without reading, just so we can click on "I agree" and get on with it.
Then, on the next page, we read this:
"Your survey responses will not be saved until you have completed the survey, clicked "Submit," and reached the thank-you page that confirms submission.
If you are somewhere with inconsistent internet access or do not have time to complete the entire survey now, please come back later when you will have time to complete the survey uninterrupted."
Between these two, there is not one word to point out that partial responses will still be recorded. Rather, I interpreted it to be highly likely that partial responses would not be recorded.
Especially, this phrase is unclear:
"You may choose not to answer any question...."
Much better would be...
"You may choose not to answer any one question or several questions. The answers you have given will still be recorded."
In which case I would have completed the census with roughly 75% of the questions answered.
