The US has released their stats on names for 2005. I found a link there via some blog or other, and went back to check on my name the year I was born (I wasn’t born in the US, but I wasn’t born in Australia, either). I reckon from my own personal experience, that Jennifer was the most popular name in Australia in 1967. In my residential college at university, 8% of the women were called Jennifer (or Jenny or Jen). But in the US, Jennifer was only the 10th most popular name in 1967. It only became number 1 in 1970, and then stayed there for another decade.
Freakonomics has a interesting section on baby names, where he reckons you can trace the class system in action by watching a baby name move from the upper classes down to the middle classes, and to the working classes, and then out of fashion.
I wonder whether the names Australians are likely to choose (of all classes) are ahead of the US? Or am I guilty of over-analysing my (admittedly sparse) data. Strangely enough, we never managed to export Kylie to anywhere else.
