For those who didn't know, the Social Security Administration keeps track of the most popular baby names for every decade. And for new parents who have not decided on a name yet, sometimes looking at popular names from previous years can give some really great baby name ideas. For families that are expecting a girl, there are tons of classic options that were really popular in the 2000s — and are still commonly used and loved today. (For those who are expecting a boy then check out this list.) A lot of these names have been around for a long time, while some didn't take off in the US until the 1990s and 2000s.
Most of these popular 2000s names are feminine, classic, and easy to spell. A lot of them have Greek or Hebrew origins, including a couple biblical names like Abigail and Sarah. Some gained popularity through popular culture. For example, in 2002, Rachel and Ross had their daughter Emma on the hit show Friends. Due to the show's popularity, it is likely that the show is part of the reason that Emma was the third most popular name of the 2000s. Names like Isabella and Madison didn't peak in popularity until the mid to late 2000s and are still commonly chosen by new parents today. There are also a couple of unexpected top names of the 2000s, like Chloe and Ava. From baby girl names that have been around for more than a century to ones that didn't pop up until about 10 years ago, this list might just surprise a mom-to-be with the perfect name.
