How many people are named Dayon, and how old are they?
An estimated 740 Americans named Dayon and born in the U.S. are alive in 2026 (98% of everyone recorded); the median is 23 years old and half are between 16 and 29. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 604 people named Dayon (64 women and girls, 540 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 693 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.

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).
