share of the girls 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.
