Is Niall a boy’s or a girl’s name?

Niall has been recorded only for boys: SSA lists no girls with the name in 68 years of records (it lists a name only in years with 5 or more babies of a sex).

Girls and boys named Niall: the SSA national file counts each sex separately.

How many people are named Niall, and how old are they?

2,030 alive in 2026, estimated

That is 97% of the 2,094 Americans ever recorded as Niall. The median Niall alive today is 14 years old; half are between 6 and 30.

The 2020 Census counted 2,052 people named Niall (18 women and girls, 2,034 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,544 born in the U.S. The Census count is 33% 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 Niall is more common than its national share predicts

New York1.44×

Bars start at 1× (as often as the national share predicts).

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 Niall with the births its national share predicts year by year, for states with at least 100 births of the name.
