The New South Wales Blues are first class cricket team based at the Sydney Cricket Grounds. According to Wikipedia, they compete in most of the major cricket tournaments in the country. There is a small community interested in the team on LiveJournal and its clones with 17 people list the NSW Blues as an interest and 2 on JournalFen. This isn’t particularly big for LiveJournal, 101 people list the Sydney Swans as an interest and 100 people list the West Coast Eagles as an interest in comparison. The teams sits between the Carlton Blues at 18 and the Cronulla-Sutherland Sharks at 16.
Of the two people on JournalFen, only one lists their year of birth: 1975. Of the 17 on LiveJournal, ten list their year of birth. On LiveJournal, the mean year of birth is 1986.4, median is 1987.5 and mode of 1992. This is pretty close to the Sydney based Canterbury-Bankstown Bulldogs community on LiveJournal where mean is 1985 and median is 1987. No other Sydney based teams where I have this data for other networks are as close to the team age wise.
Most fans are Australian with both JournalFen people listing the country as their place of residence and 14 of the 17 on LiveJournal being from Australia. Of the other three, one does not list a country, one is from Canada and one is from New Zealand. Of the Australians on JournalFen, one is from New South Wales and one is from the ACT. On LiveJournal, 2 are from the ACT, 8 are from New South Wales and 2 are from Victoria. All but one of the people from New South Wales list themselves as being from Sydney; the one who doesn’t is from Gosford, which isn’t that far from Sydney.
