The count never rose above 2 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. Source: Ministry of Digital Affairs, PESEL register (dane.gov.pl)

Not on the record in Puerto Rico, Ireland, New Zealand and Scotland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
