Appreciate your specific concerns Brian and I am sure there will be many inaccuracies, however, I guess it is no different than all the other census/record transcriptions where there is always this possibility.
As genealogists one of the things we must always follow up is the original source which most of us are aware of.
However gratitude must be expressed for the effort of getting this the first national census digitilised and online, even withstanding all the problems of the past few months.
I augurs well for future such projects and serves as a wonderful "starting-point" research source
