Austria

last on record 2024

Wiliam 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 1 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.

Chile

Wiliam is not on the 2021 record for Chile, where nametree keeps the spellings that reached 5 registrations in some year.
The count never rose above 5 in a year, too few to chart.

First-name registrations with Chile’s civil registry by year of registration, 1920–2021, counted as spelling groups (Sofía, Sofia and Sofìa are one name, shown with its most-registered spelling); the registry withholds nothing, nametree keeps the groups that reached 5 registrations in some year, and shares divide by every registration of the year.

Civil-registry acts in Mexico City by registration year. Counts are lower bounds (names under 6 in a month and borough are removed at source) and count name-instances, not people; compound names are split, so “Maria Jose” counts under each part. 2023, a partial extract through 3 Mar with no cell on record for this name, is excluded.

Montevideo City

last on record 2001

Wiliam is not on the 2011 record for Montevideo, whose registry withholds nothing, so the spelling was not given there that year.
The count never rose above 3 in a year, too few to chart.

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. Source: Servicio de Registro Civil, Intendencia de Montevideo, Partidas de Registro Civil de Montevideo (Licencia de Datos Abiertos - Uruguay); 2012 dropped as partial

Poland

last on record 2013

Wiliam 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. 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 7 other recordsWhy
  • Not on the record in Puerto Rico, Ireland, New Zealand and Scotland: those registries withhold small counts, so rare uses may sit below their floors.
  • 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.
