If you just had a baby last year and called him Noah or her Emma, then you're far from original. 

Those first names were the most popular for boys and girls in 2015, according to new data released by the Social Security Administration. 

According to its list, Liam, Mason, Jacob, William, Ethan, James, Alexander, Michael and Benjamin were the remaining top 10 boys name.

For girls, Olivia, Sophia, Ava, Isabella, Mia, Abigail, Emily, Charlotte and Harper were also the most popular names.

Noah and Emma both came in first for a second year in a row, with Noah, making its third appearance in a row on the list.

The Social Security Administration not only keeps a database of most popular names throughout the country from each year, but also ranks  first name use by state.

In New York, Liam and Olivia were the most popular, with the national favorites coming in at number two for Emma and number four for Noah.

For Massachusetts residents, Benjamin and Olivia were number one. Lucas (eight), and Jack and Grace (10) were some top names that didn’t make the national list.

Pennsylvanians preferred Mason and Olivia, but also included in their top 10 Logan at number six, Carter at number eight and Avery at number nine.

Despite the popular use of more unusual baby names in recent years, these top lists show that classic names, such as William and Michael are still selected by many parents. 

The Social Security Administration, however, is seeing an increase in popularity in names, that for now, many of never heard of — Riaan, Huxley and Wilder for boys, and Alaia, Meilani and Aitana for girls.

At the same time, certain names fall out of use. In the last year, the boy’s names Arnav, Jayse and Neymar saw the largest decrease.

Naming girls Annabell — in a variety of spellings — was on the decline. But the biggest name to drop in use was Isis. No explanation needed.
