Liberty is from the Latin libertas (freedom) — embodied in the Statue of Liberty (Frédéric Auguste Bartholdi, 1886) — the gift from France to the United States that became one of the most-recognized symbols of human freedom worldwide. The Statue of Liberty receives 4.5+ million visitors annually; the inscription on its base from Emma Lazarus's poem "The New Colossus" (1883) — "Give me your tired, your poor, your huddled masses yearning to breathe free" — is among the most-quoted lines in American literature.
Liberty does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Liberty reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
