The fines for refusing completion of this document could be up to £1000.....this didn't deter 1.5 million households from not completing the last census........I haven't yet been able to find out how many of these were subject to legal intervention.

I am sure that I read somewhere that the information is being correlated by a US company, and that the EU would have access to the info......but looking at the website of the ONS, it says that it will be illegal for information from census forms to be used by anyone, either in the UK or outside the UK......and I know that it would probably be difficult for anyone to trace my own personal form......however, I still don't like to give personal/private information that is of no real use to anyone.
You should be able to put MYOB to questions that you consider to be intrusive, and of no value when commissioning infrastructure or services.
