Girls and boys named Isaiah: the SSA national file counts each sex separately.

How many people are named Isaiah, and how old are they?

246,000 alive in 2026, estimated

That is 96% of the 254,710 Americans ever recorded as Isaiah. The median Isaiah alive today is 18 years old; half are between 11 and 25.

The 2020 Census counted 175,788 people named Isaiah (476 women and girls, 175,312 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 215,996 born in the U.S. The Census count is 19% 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).

Relative to its national share, Isaiah is most over-represented in New Mexico: since 1910 it was given 2.1 times as often there as its national share each year would predict.

States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among boys’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Isaiah with the births its national share predicts year by year, for states with at least 100 births of the name.
