Austria
last on record 2024
Mat is not on the 2025 record for Austria, which publishes every first name down to a single birth, so the name was not given there that year.
The count never rose above 2 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. Shares divide by Statistik Austria’s count of live births from 2010, and before that by the file’s own total for the year.

Not on 12 other recordsWhy
- Not on the record in Argentina, Puerto Rico, Canada, 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 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 the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years.
- Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
