The bar shows how near the top of each country's list the name sits, on a scale where #1 fills the row and #1,000 is a sliver. The figures beside it are the real rank and the babies recorded that year.

Irish figures withhold any name given to fewer than three babies in a year, so a gap means the name fell below that floor rather than went unused. The Central Statistics Office began recording the síneadh fada in 2018, so accented and unaccented spellings are counted separately from that year on. Data & sources.
