Is Zeta a boy’s or a girl’s name?
Zeta has been recorded only for girls: SSA lists no boys with the name in 104 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Zeta: the SSA national file counts each sex separately.
How many people are named Zeta, and how old are they?
An estimated 708 Americans named Zeta and born in the U.S. are alive in 2026 (52% of everyone recorded); the median is 21 years old and half are between 13 and 60. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 772 people named Zeta (757 women and girls, 15 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 688 born in the U.S. The Census count is 12% 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.
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).

Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
