The Social Security Administration has come out with its annual list of the most popular baby names, and for the 13th straight year Jacob was the number one name for a boy. This is part of a broader trend toward names from the Old Testament (or possibly ‘Twilight‘), with Noah snagging the fifth spot and Elijah and Joshua at 13 and 14.

But the number two boy name in America seems to draw its inspiration from a completely different kind of source. Mason, which jumped 10 spots to snag number two, started its rise up the ranks when reality TV star Kourtney Kardashian gave birth to Mason Kardashian in December of 2009.

For girls, Sophia ended Isabella’s two-year reign at the top (again with the ‘Twilight’ thing), bumping it to number two. Emma, Oliva and Ava rounded out the top five.

The biggest riser among girl names was Briella, which jumped from the 394th spot to 497. Briella Calafiore stars in the reality show ‘Jerseylicious‘ and is likely responsible for the name’s sudden popularity.

There are, however, limits on pop culture’s influence on naming. We’ve listed the top 20 names for boys and girls below, and you will notice there is no Kim or Khloe or Kourtney. (Or Lamar or Kris or Kanye or Scott, for that matter.)
