Is Lilli a boy’s or a girl’s name?
Lilli has been recorded only for girls: SSA lists no boys with the name in 86 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Lilli: the SSA national file counts each sex separately.
How many people are named Lilli, and how old are they?
3,220 alive in 2026, estimated
That is 95% of the 3,383 Americans ever recorded as Lilli. The median Lilli alive today is 19 years old; half are between 14 and 26.
The 2020 Census counted 3,758 people named Lilli (3,748 women and girls, 10 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 3,036 born in the U.S. The Census count is 24% above that prediction. Possible reasons: the Census records the name people give, which for many is the short form Lilli rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.

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).

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