An estimated 250 Americans named Kasidee and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 20 years old and half are between 13 and 26. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 209 people named Kasidee (209 women and girls, 0 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 246 born in the U.S. The Census count is 15% below that prediction.
