New arrivals: The most popular baby names of 2015

Story highlights

  • Noah and Emma are the most popular baby names for a second year in a row
  • Benjamin and Harper are new additions to the top 10 list

(CNN)Now you're just showing off, Noah and Emma.

For the second year in a row, they are the most popular baby names in the United States, according to the Social Security Administration. 2015 is actually the third consecutive year at the top for Noah.
    We said our farewells to other perennial favorites -- Daniel for boys and Madison for girls -- as two new baby names reached the Top 10: Benjamin for boys and Harper for girls. This is the first time either name has cracked the list of most popular names.
    The lists for boys and girls haven't changed much, with only a few shifts up and down. Perhaps Charlotte, a newcomer to the list last year, is a more popular name after the birth of British royal baby Princess Charlotte Elizabeth Diana in May 2015. James and Michael also swapped places, with the former growing in popularity.
    The boy names are a mix of classics and nods to popular actors and pop culture. The name Liam has steadily been on the rise in the top 10 since 2012, when the first "Hunger Games" film, starring Liam Hemsworth, premiered.
    The Social Security Administration is able to share the ranking because parents provide the names of children when they apply for Social Security cards. The agency started releasing its popular baby name list by gender in 1997 but has collected names dating back to 1880.
    Beyond the top 10, less-traditional names are also on the rise. For girls, Alaia spiked from No. 2,676 in 2014 to No. 664 in 2015. Perhaps this can be traced to Alaia Baldwin, a model and the daughter of actor Stephen Baldwin, or fashion designer Azzedine Alaia, the Social Security Administration noted.

    Meilani, Adaline and Zelda are also growing in popularity. Meilani is the name of Jersey Shore star Jenni "JWoww" Farley's daughter, born in 2014, as well as the middle name of "Soul Surfer" and shark attack survivor Bethany Hamilton. Adaline was Blake Lively's character in the 2015 film "The Age of Adaline," and Zelda could be attributed either to popular video game "The Legend of Zelda" or to continued fascination with writer Zelda Fitzgerald, the wife of F. Scott Fitzgerald.
    For boys, the name Riaan jumped from No. 2,286 to No. 926. This name is connected with the son of popular Bollywood actor Riteish Deshmukh. Huxley, Omari and Jabari are also rising on the list of popular names. Omari Hardwick is an actor who has appeared on the shows "Power" and "Being Mary Jane," while Jabari Parker plays basketball for the Milwaukee Bucks.
    As for Huxley, the agency is stumped, questioning whether "Brave New World" author Aldous Huxley is receiving renewed attention.
