Europa is from the Greek Eurōpē (Εὐρώπη — wide-faced). Europa in Greek mythology is the Phoenician princess who became the eponymous figure of the continent of Europe — daughter of King Agenor of Tyre, abducted by Zeus in bull form across the Mediterranean to Crete, where she bore King Minos, Rhadamanthys, and Sarpedon. Appears in the Iliad, Odyssey, Ovid's Metamorphoses, and Moschus's Europa poem (2nd c. BCE). The European Union is named in her honor — 27 member states, 450 million population.
Europa 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 Europa reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
