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.

Births in the department of Montevideo (not all of Uruguay) by first name and year of birth, 1940–2011, from the city’s civil registry, which writes names in capitals, almost always without accents; counted as spelling groups (accent and punctuation variants merged), nothing is withheld at source, and 2012 is excluded as a partial year.

South Australia
last on record 2015

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.

Not on the record in Puerto Rico, Ireland, New Zealand, Scotland and Poland: 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 Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
