Girls and boys named Sione: the SSA national file counts each sex separately.
How many people are named Sione, and how old are they?
1,470 alive in 2026, estimated
That is 97% of the 1,510 Americans ever recorded as Sione. The median Sione alive today is 21 years old; half are between 11 and 32.
The 2020 Census counted 1,797 people named Sione (47 women and girls, 1,750 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,292 born in the U.S. The Census count is 39% above 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.

An estimate, not a count. SSA’s files count people born in the United States who received a Social Security number, so anyone born abroad is not in them; before 1937 most people got a number as adults, and their survival is counted from that age.
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 Sione is more common than its national share predicts
Relative to its national share, Sione is most over-represented in Hawaii: since 1973 it was given 20.1 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 boys’ 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 Sione with the births its national share predicts year by year, for states with at least 100 births of the name.
