Is Sylvin a boy’s or a girl’s name?

Girls and boys named Sylvin: the SSA national file counts each sex separately.
How many people are named Sylvin, and how old are they?
Almost everyone recorded as Sylvin was born before 1900, so the estimate of Americans with the name alive today rounds to none. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 101 people named Sylvin (18 women and girls, 83 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2 born in the U.S. The Census count is 50.5 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 4 names spelled alike, given to 4,058 babies since 1880, Sylvin is the fourth most given (1.3% of them). In 2025 none of their 126 babies recorded by SSA was a Sylvin (SSA lists a name only with 5 or more babies of one sex).

Some are separate names, not spellings of one.
