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.

The count never rose above 3 in a year, too few to chart.
First names given to children born in Poland by year of birth, 2000–2025, from the PESEL population register (Ministry of Digital Affairs); exact spellings count separately (Łukasz and Lukasz are different names), names given fewer than 5 times in a year were left off the list through 2012 and fewer than 2 times from 2013, and the register also counts children born abroad, so its yearly sums run above Poland’s live births. Shares divide by the register’s own published total for the year, never by births. This registry counts each spelling separately; the figures above are for the exact spelling Mathéo, and accented spellings are separate names.
