Here's an interesting little interactive poll yokey-ma-bob from the Irish Times website where you can look up the frequency of first names given to kids in the last ten years.
A quick check shows that we have now gotten past the bleak, bleak years of naming young wans Britney and Shakira, also the number of Rihannas have been falling since there 2007-08 peak. The name Mary appears to be in serious decline
As for the boys, I'm truly horrified that any one would call their young fella Brooklyn or Braxton!!! The number of Johns remains relatively constant, but David is in sharp decline.
