Is Mattis a boy’s or a girl’s name?
Mattis has been recorded only for boys: SSA lists no girls with the name in 18 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Mattis: the SSA national file counts each sex separately.
How many people are named Mattis, and how old are they?
An estimated 462 Americans named Mattis and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 8 years old and half are between 5 and 9. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 383 people named Mattis (27 women and girls, 356 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 320 born in the U.S. The Census count is 20% above that prediction. Possible reasons: the Census counts people born abroad, whom SSA’s files leave out, and it records the name people give, which SSA may have recorded under another spelling or as part of a compound name.
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).
