Is Zoi a boy’s or a girl’s name?
Zoi has been recorded only for girls: SSA lists no boys with the name in 39 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Zoi: the SSA national file counts each sex separately.
How many people are named Zoi, and how old are they?
An estimated 884 Americans named Zoi and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 15 years old and half are between 9 and 21. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 848 people named Zoi (833 women and girls, 15 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 744 born in the U.S. The Census count is 14% above that prediction. Possible reasons: the Census records the name people give, which for many is the short form Zoi rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
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).
