:::: "Australain" is omitted from HighKing's synthesis, even though it's a synonym for "anglo-celtic" not that it would make Synthesis and using an unreliable source permisable, but it does make the logic even poorer. 
 :::: One of many sources that say census ancestry data is unreliable. http://www.springerlink.com/content/v30225143x313363/ "It looks at the collection of ancestry statistics as a bold attempt at an impossible task which has yielded results that are often inaccurate, sometimes misleading and liable to abuse in their interpretation." This is pertaining to ABS collection of ancestry statistics. 
 ::::If you look into the issue at all you'll see that census ancestry data is considered unreliable globally consider "German" being the largest white ancestry group in the USA for instance. Census ancestry shouldn't be in wikipedia at all without scholarly analysis, but the synthesis omitting the largest anglo-celtic group makes this by far the worst abuse of unreliable information.
