Is Kaileigh a boy’s or a girl’s name?

How many people are named Kaileigh, and how old are they?
2,740 alive in 2026, estimated
That is 99% of the 2,774 Americans ever recorded as Kaileigh. The median Kaileigh alive today is 20 years old; half are between 14 and 27.
The 2020 Census counted 2,224 people named Kaileigh (2,216 women and girls, 8 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,582 born in the U.S. The Census count is 14% 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.
Alive today, by age
Alive today, by generation
| Generation | Born | Alive |
|---|---|---|
| Millennials | 1981-1996 | 496 |
| Generation Z | 1997-2012 | 1,590 |
| Generation Alpha | 2013-2025 | 655 |
An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
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).

States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among girls’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Kaileigh with the births its national share predicts year by year, for states with at least 100 births of the name.
