Is Addalyn a boy’s or a girl’s name?

How many people are named Addalyn, and how old are they?
3,070 alive in 2026, estimated
That is 99% of the 3,086 Americans ever recorded as Addalyn. The median Addalyn alive today is 10 years old; half are between 6 and 13.
The 2020 Census counted 2,060 people named Addalyn (2,056 women and girls, 4 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,328 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.

Alive today, by generation
| Generation | Born | Alive |
|---|---|---|
| Generation Z | 1997-2012 | 718 |
| Generation Alpha | 2013-2025 | 2,350 |
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 Addalyn is more common than its national share predicts
Relative to its national share, Addalyn is most over-represented in Indiana: since 1998 it was given 1.9 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 Addalyn with the births its national share predicts year by year, for states with at least 100 births of the name.
