How many people are named Kaiyah, and how old are they?
1,230 alive in 2026, estimated
That is 99% of the 1,235 Americans ever recorded as Kaiyah. The median Kaiyah alive today is 11 years old; half are between 6 and 16.
The 2020 Census counted 766 people named Kaiyah (759 women and girls, 7 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 894 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.

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).
