Is Sianni a boy’s or a girl’s name?
Sianni has been recorded only for girls: SSA lists no boys with the name in 28 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Sianni: the SSA national file counts each sex separately.
How many people are named Sianni, and how old are they?
An estimated 570 Americans named Sianni and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 4 years old and half are between 2 and 20. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 194 people named Sianni (194 women and girls, 0 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 248 born in the U.S. The Census count is 22% below that prediction. Possible reasons: people who give a short form or another name to the Census, and a survival estimate that can run high.
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).

Where Sianni is more common than its national share predicts
Relative to its national share, Sianni is most over-represented in Pennsylvania: since 1996 it was given 4.9 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among girls’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Sianni with the births its national share predicts year by year, for states with at least 100 births of the name.
