Way to go, Aidan. You've held onto the number one spot for eight straight years.
Sophia, you're doing all right, too, with three years of bragging rights in the top position. We welcome Jack and Mia, new to the top 10 this year.

Today, BabyCenter released its annual list of top 100 baby names for 2012. The list is based on nearly half a million babies born this year to mothers registered with the BabyCenter website.

So why do these names have staying power? “Part of the reason it stays No. 1 is you can spell it in 45 different way,” BabyCenter’s global editor in chief Linda Murray commented on the name Aidan on TODAY today. “Moms love it.” Just last year, rocker Rod Stewart and his wife, Penny Lancaster Stewart welcomed their own little Aidan into the world.

After Aiden, the most-chosen names on the boy’s list are Jackson, Ethan, Liam, Mason, Noah, Lucas, Jacob, Jayden and Jack. As for the girls list, top picks include Emma, Olivia, Isabella, Sophia, Mia, Ava, Lily, Zoe, Chloe and Madison.

The authors of the study determined that the most likely cause for the wage bump was that physical and personality traits that make a person well-liked can also lead to more opportunity and wealth in the workplace.

Beyond the top 10, BabyCenter discovered name trends influenced by the Fifty Shades of Grey trilogy (Ana, Grey and Anastasia are up, while Christian is down), members of the English-Irish boy band, One Direction, and popular sitcom actress, Betty White.

Carrie Mazur of Gaithersburg, Md. chose the name Aidan for their son because she and her husband loved how it sounds.

"It also means 'little fire,' which sums up his in utero antics and life since birth," quipped the mother of two. “What's becoming more important to new parents is finding a name with meaning,” Murray was quoted, noting that Sophia means “wisdom."
