How many people are named Izack, and how old are they?
An estimated 417 Americans named Izack and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 18 years old and half are between 13 and 23. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 339 people named Izack (3 women and girls, 336 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 382 born in the U.S. The Census count is 11% below that prediction.
