If you answer online can you skip questions or does it have a bunch of annoying must fill answer fields that you can normally skip on the paper census.
The online form is the same as for paper and phone ... and it's quite short and basic.
You can complete it in 5-10 minutes.
The long-form doesn't exist anymore in the 10-year census and was replaced by the annual American Community Survey, which only a handful of US households answer each year (= sample).
I did it online. I did get to skip questions but only after clicking through twice. The Census was very short and I hope this means I'm not bothered with any followup.
