Meaning
modern phonetic variant of Josiah, Hebrew for 'God supports'
The story
Jasiah is the Josiah sound in a modern phonetic spelling, God supports in the old Hebrew, and the anchor is one of the era's quiet giants: Josiah, the boy-king who found the lost book of the law, counts about 149,200 with its own story here. Jasiah's record is young and steep: about 130 in the 1990s, 1,900 in the 2000s, cresting at 4,500 in the 2010s, with 3,700 so far this decade, nearly all boys, about 9,600 to 650. The J-spelling keeps the sound and simplifies the road to it, the same legibility instinct Johnathan follows in our records; the support in the root passes through untouched. An old king, a young spelling, and a record climbing the way the family's records climb: steadily, and without a spike.

South Australia
last on record 2013
Jasiah 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 the record in Spain, Mexico City, Argentina, 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 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.
