Is Lex a boy’s or a girl’s name?
Lex has been given almost only to boys: 15 girls in 120 years of records.
Girls and boys named Lex: the SSA national file counts each sex separately.
How many people are named Lex, and how old are they?
3,190 alive in 2026, estimated
That is 80% of the 4,010 Americans ever recorded as Lex. The median Lex alive today is 20 years old; half are between 10 and 50.
The 2020 Census counted 3,551 people named Lex (504 women and girls, 3,047 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 2,863 born in the U.S. The Census count is 24% 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 are babies named Lex born?
The states with the most babies named Lex are California, Illinois and Georgia, with 100% of its births recorded by state in 2025.
| State | Births 2025 | Rank, boys | vs. national |
|---|---|---|---|

| Illinois | 5 | #1,413 | 0.1× |
| Georgia | 5 | #1,469 | 0.0× |
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 Lex with the births its national share predicts year by year, for states with at least 100 births of the name.
Names spelled alike
Of these 2 names spelled alike, given to 4,102 babies since 1880, Lex is the most given (98% of them). In 2025 it was given to 60 of their 60 babies (100%), again the most given.
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.
