The name was very rare outside Scandinavia until the late twentieth century. It has surged in the 2010s and 2020s, particularly in the United Kingdom, where Freya has climbed into the top 20 girl names. The Norse-revival aesthetic — Vikings, The Witcher, the broader fascination with northern mythology — has helped, but the name's sound (two syllables, easy in any language) does most of the work.
Freya 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 Freya reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
