According to the Social Security administration, Emma and Noah were the most popular baby names in 2014. For girls, Emma was followed by Olivia, Sophia, Isabella and Ava. For boys, Noah was followed by Liam, Mason, Jacob and William. The Social Security Administration’s website provides lists of the top 1,000 baby names for each year, dating to 1880. The top baby names that year were John and Mary. John is now No. 26 and Mary has fallen to No. 120. You might be wondering how the U.S. government knows such things about your newborns. This is primarily because many U.S. parents file for a Social Security number with the federal government at the same time that they file for their baby’s birth certificate with their local government.

There are many ways parents choose their children’s name depending on culture and background. Names are sometimes chosen because of their meaning and origin. Some names are passed down from generation to generation. Depending on where you are from, trends show that pop culture and religion are the biggest influencers when it comes to name popularity. For instance, biblical Noah held the top place for two years in a row, and the name Emma who became popular after Rachel, a character on the TV show “Friends,” named her baby Emma. Emma has been ranked among the top four baby names for girls since 2002, though it was just behind Sophia in 2013.

Britain’s Prince William and his wife Catherine, Duchess of Cambridge, named their baby daughter Charlotte which cracked the top 10 list of popular baby names for the first time. The daughter of Bill and Hillary Clinton, Chelsea Clinton, named her daughter Charlotte. “Charlotte’s definitely going to hit the top three in the next three years,” said Jennifer Moss, founder and CEO of Babynames.com.
