Kylie is of Australian origin, meaning 'boomerang'. It gained popularity as a girls' name in the late 20th century, likely influenced by the character Kylie minogue in the Australian soap opera Neighbours. The name has since been popularized internationally due to the fame of Kylie Minogue, the singer and actress who portrayed that character.
The name Kylie peaked in popularity between the late 1980s and early 1990s, with a high of 20 births in 1989, indicating its influence during this period. However, it has since declined in usage, with fewer than 10 births per year recorded from 2007 onwards.
