How many people are named Kailin, and how old are they?
1,390 alive in 2026, estimated
That is 99% of the 1,410 Americans ever recorded as Kailin. The median Kailin alive today is 22 years old; half are between 15 and 30.
The 2020 Census counted 1,485 people named Kailin (1,262 women and girls, 223 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,274 born in the U.S. The Census count is 17% 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.
Alive today, by age
Alive today, by generation
| Generation | Born | Alive |
|---|---|---|

| Generation Z | 1997-2012 | 729 |
| Generation Alpha | 2013-2025 | 300 |
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).
