An estimated 356 Americans named Isabellah and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 15 years old and half are between 11 and 18. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 268 people named Isabellah (264 women and girls, 4 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 327 born in the U.S. The Census count is 18% below that prediction.
