Chile

last on record 2020

Rainier 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 7 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.

Mexico City City

last on record 2016

Rainier is not on the 2022 record for Mexico City, where small counts are withheld at source.
The count never rose above 3 in a year, too few to chart.

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.

South Australia

last on record 2004

Rainier is not on the 2017 record for South Australia, whose registry publishes every name given that year.
The count never rose above 2 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.

Not on 11 other recordsWhy
  • Not on the record in Argentina, Puerto Rico, England and Wales, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
  • 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 Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only).
  • Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
