How many people are named Kortni, and how old are they?
1,160 alive in 2026, estimated
That is 98% of the 1,189 Americans ever recorded as Kortni. The median Kortni alive today is 32 years old; half are between 25 and 37.
The 2020 Census counted 1,046 people named Kortni (1,029 women and girls, 17 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,170 born in the U.S. The Census count is 11% 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).
