Follow this link and go to a page at a site called flowingdata where data has been crunched on USA names born in different years in order to produce a search device that guesses your name based on what decade you were born in, whether you are male or female (or have a male or female name, I guess) and what letter(s) your name starts with.
I guess the names are pretty consistent from USA to Australia.
It’s pretty close.
Go see if you’re curious.
