Is Sim a boy’s or a girl’s name?
Sim has been recorded only for boys: SSA lists no girls with the name in 114 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Sim: the SSA national file counts each sex separately.
How many people are named Sim, and how old are they?
An estimated 461 Americans named Sim and born in the U.S. are alive in 2026 (24% of everyone recorded); the median is 66 years old and half are between 52 and 77. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 1,238 people named Sim (482 women and girls, 756 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 564 born in the U.S. The Census count is 2.2 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Sim 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).

Of these 2 names spelled alike, given to 2,040 babies since 1880, Sim is the most given (95% of them).

Some are separate names, not spellings of one.
Names that rose and fell in the same decades as Sim
