Asia is the English continent name — from the Greek Asia / Latin Asia (referring to the Lydian kingdom in Asia Minor). A top-500 US baby name since 1986. Asia Argento (born 1975) — Italian actress and director; XXX (2002) opposite Vin Diesel; The Heart Is Deceitful Above All Things (2004); central voice in the early #MeToo movement (October 2017). Asia Kreitschmann (born 1994) — German athlete.
Asia 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 Asia reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
