Ranks and shares: boys’ names in each year’s SSA file; share of all boys SSA recorded that year.
Is Mateus a boy’s or a girl’s name?
Mateus has been recorded only for boys: SSA lists no girls with the name in 32 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Mateus: the SSA national file counts each sex separately.
How many people are named Mateus, and how old are they?
An estimated 983 Americans named Mateus and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 12 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 1,291 people named Mateus (1 woman or girl, 1,290 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 731 born in the U.S. The Census count is 1.8 times 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).

Where Mateus is more common than its national share predicts
Relative to its national share, Mateus is most over-represented in California: since 1994 it was given 1.2 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 Mateus with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
