Is Kjersti a boy’s or a girl’s name?

Girls and boys named Kjersti: the SSA national file counts each sex separately.
How many people are named Kjersti, and how old are they?
An estimated 240 Americans named Kjersti and born in the U.S. are alive in 2026 (96% of everyone recorded); the median is 40 years old and half are between 34 and 47. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 350 people named Kjersti (344 women and girls, 6 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 242 born in the U.S. The Census count is 45% 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).
