Is Kais a boy’s or a girl’s name?
Kais has been recorded only for boys: SSA lists no girls with the name in 27 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Kais: the SSA national file counts each sex separately.
How many people are named Kais, and how old are they?
An estimated 419 Americans named Kais and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 9 years old and half are between 4 and 13. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 465 people named Kais (27 women and girls, 438 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 268 born in the U.S. The Census count is 1.7 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Kais 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).
