Australia
Girls' nameMeaning not yet documented
Australia has been given to 350 babies in the U.S. since 1900. It was used fewer than 5 times in 2025, so it doesn't appear in the latest year's list — today it's a genuinely uncommon pick. Its peak year was 1917, with 12 recorded.

Where Australia sits on the popularity scale
Chance at least one other child shares the name
If the other children were drawn at random from the 2020 national name distribution. Real classrooms cluster by region and community, so treat these as a floor, not a ceiling.
Put another way: gather 330,960 children born in 2020 and it's an even bet that one of them is another Australia. In a class of 30 the chance is Under 1%.
