The story in the numbers
1,000 boys have been named Cosimo in the United States since 1911, according to Social Security records. The busiest single year was 1927, with 30 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 1947, and the 1920s alone account for 22%.

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.
