Is Kelsei a boy’s or a girl’s name?
Kelsei has been recorded only for girls: SSA lists no boys with the name in 35 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Kelsei: the SSA national file counts each sex separately.
How many people are named Kelsei, and how old are they?
An estimated 333 Americans named Kelsei and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 23 years old and half are between 12 and 30. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 271 people named Kelsei (268 women and girls, 3 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 308 born in the U.S. The Census count is 12% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.
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).
