The story in the numbers
33,044 girls have been named Cleo in the United States since 1880, according to Social Security records. The busiest single year was 1920, with 1,049 births.
This is a comeback. After an early peak the name fell to a fraction of its former share, and it has been climbing again for the past decade.
Half of everyone given the name was born by 1925, and the 1920s alone account for 25%. It has spent 83 of 145 years in the top 1,000.
Cleo is used for both sexes: 26% of its bearers are boys (11,508), most of them born around 1918.

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.
