How many people are named Kaydin, and how old are they?
1,830 alive in 2026, estimated
That is 99% of the 1,852 Americans ever recorded as Kaydin. The median Kaydin alive today is 16 years old; half are between 12 and 19.
The 2020 Census counted 1,436 people named Kaydin (462 women and girls, 974 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,690 born in the U.S. The Census count is 15% 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

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).
