How many people are named Katlynn, and how old are they?
3,910 alive in 2026, estimated
That is 98% of the 3,975 Americans ever recorded as Katlynn. The median Katlynn alive today is 28 years old; half are between 23 and 32.
The 2020 Census counted 3,369 people named Katlynn (3,366 women and girls, 3 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 3,915 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 | 1,480 |
| Generation Z | 1997-2012 | 2,310 |
| Generation Alpha | 2013-2025 | 126 |
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 Katlynn is more common than its national share predicts
Relative to its national share, Katlynn is most over-represented in Indiana: since 1984 it was given 1.5 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 Katlynn with the births its national share predicts year by year, for states with at least 100 births of the name.
