Celebrity-inspired names are also high on the list, including reality show star Kourtney Kardashian’s baby's name, Mason (No. 2 for boys), and Britney Spears’s son’s name, Jayden (No. 4 for boys). Mason jumped to the top for the first time in 2011 and Jayden debuted in the top 10 in 2009.

The other top 10 names for boys were William, Noah, Michael, Ethan, Alexander, Aiden and Daniel. The other popular names for girls were Emma, Olivia, Ava, Emily, Abigail, Madison, Mia and Chloe.

Classic was in for girls' names last year: all of the most popular girls names for 2011, with the exception of Mia, appear in the top 20 most popular names of the decade.
