Is Sie a boy’s or a girl’s name?
Sie has been recorded only for boys: SSA lists no girls with the name in 19 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Sie: the SSA national file counts each sex separately.
How many people are named Sie, and how old are they?
An estimated 3 Americans named Sie and born in the U.S. are alive in 2026, too few to state an age range. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 235 people named Sie (71 women and girls, 164 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 8 born in the U.S. The Census count is 29.4 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Sie 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).
Names spelled alike
Of these 5 names spelled alike, given to 1,994 babies since 1880, Sie is the fourth most given (6.7% of them). In 2025 none of their 59 babies recorded by SSA was a Sie (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.
