Is Letti a boy’s or a girl’s name?
Letti has been recorded only for girls: SSA lists no boys with the name in 17 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Letti: the SSA national file counts each sex separately.
How many people are named Letti, and how old are they?
An estimated 595 Americans named Letti and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 7 years old and half are between 4 and 10. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 415 people named Letti (415 women and girls, 0 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 313 born in the U.S. The Census count is 33% above that prediction. Possible reasons: the Census records the name people give, which for many is the short form Letti 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).
