The count never rose above 6 in a year, too few to chart.

Live births in Austria by year of birth, 1984–2025, from Statistik Austria’s first-name statistics; spellings that differ only by special characters are counted together (umlauts stay apart), every name down to a single birth is published, and the count covers babies with Austrian citizenship only until 2009, every baby from 2010, and from 2015 also births abroad to mothers living in Austria.

Sydney is not on the 2025 record for Poland, where names given fewer than 2 times in a year are withheld at source.
The count never rose above 2 in a year, too few to chart.

First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births.
