How many people are named Kaysen, and how old are they?
7,020 alive in 2026, estimated
That is 99% of the 7,075 Americans ever recorded as Kaysen. The median Kaysen alive today is 7 years old; half are between 3 and 11.
The 2020 Census counted 3,089 people named Kaysen (356 women and girls, 2,733 men and boys).

|---|---|---|
| Generation Z | 1997-2012 | 978 |

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 Kaysen is more common than its national share predicts
Relative to its national share, Kaysen is most over-represented in Mississippi: since 1998 it was given 2.3 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 boys’ 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 Kaysen with the births its national share predicts year by year, for states with at least 100 births of the name.
