Is Cassy a boy’s or a girl’s name?

Cassy has been recorded only for girls: SSA lists no boys with the name in 65 years of records (it lists a name only in years with 5 or more babies of a sex).

Girls and boys named Cassy: the SSA national file counts each sex separately.

How many people are named Cassy, and how old are they?

1,910 alive in 2026, estimated

That is 96% of the 1,996 Americans ever recorded as Cassy. The median Cassy alive today is 39 years old; half are between 32 and 45.

The 2020 Census counted 2,248 people named Cassy (2,215 women and girls, 33 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,936 born in the U.S. The Census count is 16% above that prediction. Possible reasons: the Census counts people born abroad, whom SSA’s files leave out, and it records the name people give, which SSA may have recorded under another spelling or as part of a compound name.

An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.

Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).
