Kylie is from the Noongar Aboriginal word kayle ("boomerang") — the curved hunting weapon of southwest Western Australia. The name was popularized globally by Australian singer Kylie Minogue (born 1968) — whose 1988 cover of "The Loco-Motion" topped charts in 17 countries and whose 50+ #1 singles across multiple countries make her the highest-selling Australian artist of all time. Kylie Bunbury (Big Sky), Kylie Padilla (Filipino actress).
Kylie 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 Kylie reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
