Is Lenn a boy’s or a girl’s name?
Of the 521 Americans recorded as Lenn, 1% are girls and 99% boys.
Years with fewer than 20 babies given the name are left blank.
Girls and boys named Lenn: the SSA national file counts each sex separately.
How many people are named Lenn, and how old are they?
An estimated 314 Americans named Lenn and born in the U.S. are alive in 2026 (60% of everyone recorded); the median is 64 years old and half are between 54 and 72. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 453 people named Lenn (66 women and girls, 387 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 351 born in the U.S. The Census count is 29% above that prediction. Possible reasons: the Census records the name people give, which for many is the short form Lenn rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
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 8 names spelled alike, given to 193,114 babies since 1880, Lenn is the fifth most given (<1% of them). In 2025 none of their 2,651 babies recorded by SSA was a Lenn (SSA lists a name only with 5 or more babies of one sex).

Some are separate names, not spellings of one.
