How many people are named Keilly, and how old are they?
An estimated 605 Americans named Keilly and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 16 years old and half are between 11 and 20. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 468 people named Keilly (463 women and girls, 5 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 530 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.
