How many people are named Kadyn, and how old are they?
4,680 alive in 2026, estimated
That is 99% of the 4,732 Americans ever recorded as Kadyn. The median Kadyn alive today is 17 years old; half are between 12 and 20.
The 2020 Census counted 3,758 people named Kadyn (1,230 women and girls, 2,528 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 4,332 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
Alive today, by generation
| Generation | Born | Alive |
|---|---|---|
| Millennials | 1981-1996 | 45 |
| Generation Z | 1997-2012 | 3,240 |
| Generation Alpha | 2013-2025 | 1,400 |
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 Kadyn is more common than its national share predicts
Relative to its national share, Kadyn is most over-represented in Missouri: since 1993 it was given 1.1 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 Kadyn with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 8 names spelled alike, given to 298,871 babies since 1880, Kadyn is the seventh most given (1.6% of them). In 2025 it was given to 46 of their 7,214 babies (<1%), again the seventh most given.
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
