How many people are named Keirstin, and how old are they?
An estimated 538 Americans named Keirstin and born in the U.S. are alive in 2026 (98% of everyone recorded); the median is 26 years old and half are between 20 and 32. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 467 people named Keirstin (466 women and girls, 1 man or boy).
