I love reading about the census figures. Such rich food for thought (especially a publisher in hopeful search of the zeitgeist.)
According to the Age based on the latest census figures the mainstream is shrinking. James Jupp is quoted as saying mainstream is British-Australian Christian, and we're down to two-thirds of the population - though I wouldn't claim to be a Christain and I prefer the term Anglo-Celt to British (there's enough rebellious Irish blood still flowing). And the average Australian is a 37 year old, mother of two, still paying off a mortgage.
&, if I read this right, Judaism disapproves of the census. Which surprised me, as it would have seemed to me a statistical rather than religious execise, but I am sure there is rich and logical Talmudic reasoning at work.
The data showed "a particular growth" in non-Christian religions. And the number of Muslims has been overtaken by the number of Buddhists.
There are nearly 400 languages spoken in Australian homes with Chinese (Mandarin and Cantonese) the most common language other than English, replacing Italian and Greeks. Cantonese, alone ties with Arabic (after Greek and Italian) as the most common language other than English spoken at home. But Mandarin and Hindi are the fastest growing languages.
