Is Billi a boy’s or a girl’s name?

Girls and boys named Billi: the SSA national file counts each sex separately.
How many people are named Billi, and how old are they?
1,610 alive in 2026, estimated
That is 92% of the 1,746 Americans ever recorded as Billi. The median Billi alive today is 50 years old; half are between 41 and 56.
The 2020 Census counted 1,463 people named Billi (1,365 women and girls, 98 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 1,644 born in the U.S. The Census count is 11% 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.

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).
Names spelled alike
Of these 5 names spelled alike, given to 141,188 babies since 1880, Billi is the third most given (1.2% of them). In 2025 none of their 422 babies recorded by SSA was a Billi (SSA lists a name only with 5 or more babies of one sex).
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
Names that rose and fell in the same decades as Billi
Names whose births rose and fell across the same decades, measured on each decade’s share of births.
