In Norway, 11 boys were given the name Jo in 2025.

share of the boys on the register for that year, SSB’s own figure

People who have or have had a Norwegian ID number, emigrants left out, from Statistics Norway’s name statistics (release of January 2026): by year of birth for 1945–2020 (everyone born that year who was ever registered in Norway, including people who registered later and people who have since died) and by year of naming from 2021; only first names carried by 200 or more living people are listed, counts under 4 are withheld, and SSB merges spellings that differ only by letters outside the Norwegian alphabet. The shares are SSB’s own, of the people of that sex and year in that count; the 2025 figure counts the children named that year, and no year is a count of births.

Jo 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.

Jo is not on the 2017 record for South Australia, whose registry publishes every name given that year.
The count never rose above 4 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.
