Is Sister a boy’s or a girl’s name?
Sister has been recorded only for girls: SSA lists no boys with the name in 56 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Sister: the SSA national file counts each sex separately.
How many people are named Sister, and how old are they?
An estimated 33 Americans named Sister 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 3,836 people named Sister (3,801 women and girls, 35 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 55 born in the U.S. The Census count is 69.7 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).
