share of that year’s births on record
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. Shares divide by Statistik Austria’s count of live births from 2010, and before that by the file’s own total for the year.

South Australia
1 in 18,0002017
In South Australia, 1 boy was registered as Xaver in 2017.
The count never rose above 1 in a year, too few to chart.
Births registered in South Australia (not all of Australia) by first name and year of registration, 1944–2017, from the state’s Births, Deaths and Marriages registry, which publishes every name down to a single birth in capitals; a spelling its export repeats inside a year is counted once, and from 2018 only a top 100 is published, so the series ends at 2017.

Poland
last on record 2017
Xaver 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 6 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. Shares divide by the register’s own published total for the year, never by births. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)
Not on the record in Spain, Mexico City, Argentina, Puerto Rico, England and Wales, Canada, Ireland, New Zealand and Scotland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Chile record: nametree keeps spellings that reached 5 registrations in some year, so rarer uses are not shown. Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
