Is Ailyn a boy’s or a girl’s name?

Girls and boys named Ailyn: the SSA national file counts each sex separately.
How many people are named Ailyn, and how old are they?
4,450 alive in 2026, estimated
That is 99% of the 4,490 Americans ever recorded as Ailyn. The median Ailyn alive today is 13 years old; half are between 7 and 18.
The 2020 Census counted 3,184 people named Ailyn (3,161 women and girls, 23 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 3,536 born in the U.S. The Census count is 10% 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 |
|---|---|---|
| Generation X | 1965-1980 | 5 |
| Millennials | 1981-1996 | 65 |
| Generation Z | 1997-2012 | 2,090 |
| Generation Alpha | 2013-2025 | 2,300 |
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).

Where Ailyn is more common than its national share predicts
Relative to its national share, Ailyn is most over-represented in Arizona: since 1975 it was given 2.1 times as often there as its national share each year would predict.
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 Ailyn with the births its national share predicts year by year, for states with at least 100 births of the name.
