Isle of Man Civil Registry — per-name registration counts (press), 2023 on the left; every record we hold for Isle of Man on the right. A dashed line means the name is not in our top ranks for this country at all.

The register counts one population in one year — everyone it enumerates, once. Our corpus counts records: historical registers going back decades, the diaspora, business and place records, and several generations of births. A name that was common two generations ago outranks a name common today; a name whose spelling scatters across sources (diacritics dropped, transliterated differently) loses ground, because only its dominant spelling is ranked.

Registers & sources

    Isle of Man Civil Registry / General Registry. Counts: residents. given. 9 forms. 2022–2024. Licence: unknown.

    What we know about this register

    The Isle of Man Civil Registry releases how many times each name was registered; the COUNTS appear in press write-ups (iomtoday.co.im / Manx Radio), while gov.im gives ranks only. Per-name counts by sex+year for 2022, 2023, 2024 (2021/2025 press reports are rank-only and excluded). CAVEAT: names are reported as spelling-variant CLUSTERS (e.g. "Isabelle/Isabella", "Theo/Theodore"), not single names, so the `name` field stores the cluster string verbatim; counts are small (~4-10). rank derived from count ordering within sex+year. Re-checked 2026-08-06 (task #42 sweep) for a live per-name lookup on gov.im beyond the annual press-reported counts already catalogued here: the Central/Civil Registry's online certificate ordering tool needs a known year (and ideally volume/page or town), not a name, and returns no existence/count signal for an unmatched name. No online per-name search tool exists. No new source added.

About this data

Official figures are reproduced from the register named beside them, at the year named beside them, and are never combined across registers. The "across all records" ranking counts records in our own corpus — historical registers, the diaspora, business and place records — and is not a population count. Bearer estimates are omitted where a name accounts for more than a quarter of a country's records, because the estimate is not defensible there. Names listed by reference works and licensed name dictionaries are cited as attesting a name; their figures are not published.
