For all of the top baby names of 2021, and to see where your name ranks, visit the Social Security website.

Social Security began compiling the baby name list in 1997, with names dating back to 1880.

At the time of a child's birth, parents supply the name to the agency when applying for a child's Social Security card, thus making Social Security America's source for the most popular baby names.

Each year, the list reveals the effect of pop-culture on naming trends -- including the fastest rising boys and girls names in 2021.
