Meaning
“Italian/Spanish form of Claudius, traditionally 'lame'”
The story
Claudio begins with an immigrant: legend says the Sabine Attius Clausus came to Rome with his followers in 504 BC and founded the clan history knows as the Claudii, emperors included. What the name meant is honestly disputed. The usual reading is Latin claudus, lame, but the Spanish reference tradition rejects that gloss outright, and scholars concede the whole derivation may be wrong. The bearers never waited for a ruling: Claudio Monteverdi's L'Orfeo of 1607 is the earliest opera still widely performed, and Claudio Arrau, the Chilean who could read music before he could read words, became one of the twentieth century's most admired pianists. Brazil's 2022 census counted 311,341 Claudios, rank 89, a third of them born in the 1970s alone. The American record adds about 5,500 across the century. Whatever it once meant, it has meant music for four hundred years.

The count never rose above 7 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.
