South Australia

In South Australia, 2 girls were registered as Kailey in 2017.
The count never rose above 5 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.

share of that year’s registrations in the city

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.

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.

Not on the record in Spain, Argentina, Puerto Rico, New Zealand 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 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.
