Top Baby Names of 2018

What the Data Says About 2018

The Social Security Administration's national 2018 file shows 1,318,272 births concentrated in the top 100 boy and top 100 girl names, the segment of U.S. baby-name data released to the public for that year. The #1 boy name of 2018 was Liam, with 19,974 births registered nationally. The #1 girl name of 2018 was Emma, with 18,818 births nationally. The top 100 boys captured 752,543 births compared with 565,729 for the top 100 girls — consistent with the historical SSA pattern in which a smaller pool of boy names dominates a larger share of annual births while girl names are more evenly distributed.

2018 sits within a specific era of U.S. naming trends. 2018 reflects the contemporary naming landscape — shorter names, -a endings for girls, classic revivals for boys, and a steadily flattening distribution in which no single name dominates the way they did mid-century. Liam and Emma leading 2018 fits this broader cultural signature.

These rankings come directly from Social Security Administration card applications and represent approximately 96% of all U.S. births in 2018. Names with fewer than five occurrences nationally in 2018 are excluded from SSA's public file to protect privacy, meaning the true number of unique names given in 2018 is significantly larger than any public top-100 list can show. Each spelling variation is counted separately — Sophia and Sofia, Aiden and Ayden — so rankings reflect only the specific spelling filed on the SS card, not combined name pools.
