The story in the numbers

1,727 boys have been named Kiernan in the United States since 1957, according to Social Security records. The busiest single year was 2008, with 77 births.

Half of everyone given the name was born by 2006, and the 2000s alone account for 37%.

Kiernan is used for both sexes: 28% of its bearers are girls (678), most of them born around 2002.

What this page does not tell you. The Social Security data records how many babies were given a name, not what the name means or where it comes from — so neither do we. Counts cover people with a Social Security number; names given to fewer than five babies in a year are withheld. More on the data.
