Is Tri a boy’s or a girl’s name?
Tri has been recorded only for boys: SSA lists no girls with the name in 43 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Tri: the SSA national file counts each sex separately.
How many people are named Tri, and how old are they?
An estimated 643 Americans named Tri and born in the U.S. are alive in 2026 (97% of everyone recorded); the median is 29 years old and half are between 19 and 39. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 5,535 people named Tri (352 women and girls, 5,183 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 644 born in the U.S. The Census count is 8.6 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Tri rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
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 Tri is more common than its national share predicts
Relative to its national share, Tri is most over-represented in California: since 1976 it was given 1.7 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 Tri with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 5 names spelled alike, given to 3,885 babies since 1880, Tri is the third most given (17% of them). In 2025 none of their 44 babies recorded by SSA was a Tri (SSA lists a name only with 5 or more babies of one sex).
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
