Is Mosiah a boy’s or a girl’s name?
Mosiah has been recorded only for boys: SSA lists no girls with the name in 34 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Mosiah: the SSA national file counts each sex separately.
How many people are named Mosiah, and how old are they?
An estimated 789 Americans named Mosiah and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 10 years old and half are between 6 and 19. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 508 people named Mosiah (6 women and girls, 502 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 566 born in the U.S. The Census count is 10% 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.
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).
