Is Irelynn a boy’s or a girl’s name?

How many people are named Irelynn, and how old are they?
1,730 alive in 2026, estimated
That is 99% of the 1,740 Americans ever recorded as Irelynn. The median Irelynn alive today is 12 years old; half are between 7 and 17.
The 2020 Census counted 1,175 people named Irelynn (1,172 women and girls, 3 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,353 born in the U.S. The Census count is 13% 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

| Generation | Born | Alive |
|---|---|---|
| Generation Z | 1997-2012 | 703 |
| Generation Alpha | 2013-2025 | 1,030 |
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).

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 Irelynn with the births its national share predicts year by year, for states with at least 100 births of the name.
