Is Jiro a boy’s or a girl’s name?
Jiro has been recorded only for boys: SSA lists no girls with the name in 45 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Jiro: the SSA national file counts each sex separately.
How many people are named Jiro, and how old are they?
An estimated 218 Americans named Jiro and born in the U.S. are alive in 2026 (53% of everyone recorded); the median is 12 years old and half are between 5 and 19. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 475 people named Jiro (7 women and girls, 468 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 161 born in the U.S. The Census count is 3.0 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).
Names spelled alike
Of these 2 names spelled alike, given to 3,616 babies since 1880, Jiro is the second most given (11% of them). In 2025 it was given to 5 of their 383 babies (1.3%), again the second most given.
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.
