Counts apply only to the exact spelling, place, year and recorded usage shown. Places are separate; these figures are never added into a worldwide total. Missing or suppressed records never mean zero.
| Place | Year | Recorded usage | Published births | Rank | Notes |
|---|---|---|---|---|---|
| Canada | 2025 | Boys | 48 · preliminary | 605 | 2025 figures are preliminary. Quebec counts below five are randomly imputed by the publisher before national aggregation. Accents are removed in the source; this profile was matched only where the catalog spelling was unambiguous. Unpublished values are unknown, not zero. Rank basis: source published. |
| France | 2024 | Boys | 5 (rounded to 5) | 3319 | Counts are rounded to the nearest multiple of five. Ranks use unrounded publisher counts with randomly ordered ties; equally rounded counts can have different ranks. National coverage excludes Mayotte before 2012. Missing years are unavailable, not zero. Automated direction labels are withheld for this rounded-count series. Rank basis: source published. |
| England & Wales | 2025 | Boys | 304 | 167 | Source-reported counts; unpublished names are not zero. Rank basis: source published. |
