Teacher: Now, understand the problem? Solve this instance: (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.Noah and Emma are the most popular baby names for a second year in a rowBenjamin and Harper are new additions to the top 10 list
