Surely we should be focusing on the important issues - making sure that the census continues, and getting the law changed so that we can access the historic England & Wales BMD registers online?
It is interesting to me as a family historian with almost uniquely Scottish records that those with English records are so fixated on the census. Now don't get me wrong I can understand fully why that is when you don't have any online records for BMDs and are forced to rely on indexes and very expensive certificates. A census to my Scottish research is important but far less so that a marriage or death certificate (births almost always simply confirm what you already know). Marriage certificates are the most valuable as they give the names of all four parents including the mothers maiden names, and death certificate gives father and mothers names of the deceased (where known). The census is a lot less important as it simply confirms family groups.
So I'd echo Peter's call for more focus on getting the bread and butter data of actual BMD registers online. Whilst you'll never have the richness of data that was collected for the Scottish records, mainly because of the English tradition of the wife losing all her former identity on marriage, you would at least have original source documents to go on without having to purchase an expensive certificate.
For the record the difference in Scotland is that you can view/print/save a scan of a certificate for £1.20 to use as you wish for your own research. However you can still get an official printed certificate as per the English ones for £8 the difference is the former has no legal standing the latter is acceptable proof in a court of law.
