Data Confidence

Evidence: ModerateCompleteness: SubstantialEditorial review: 2026-07-21

Confidence in the evidencebehind this name's data — never a rating of the name itself, and never affected by how well it matches your preferences. How this is assessed

Because: backed by officially or academically authoritative sources, recently verified, popularity data covers multiple regions.

Source authority

Averaged from the real per-claim source-authority assessments already computed for this name's meaning/origin/pronunciation/popularity evidence.

Independent corroboration

Averaged from the real per-claim supporting-source counts already computed for this name's evidence.

See full evidence assessment (8 dimensions, 1 not yet tracked)

Source agreement

No recorded source disagreement for this name's meanings or origins.

Recency

Calculated from how long ago this record was last verified (2026-07-21), against a 270-day staleness threshold.

Geographic relevance

Calculated from the number of geographies with official popularity data (7) — broader official coverage means the evidence base is relevant to more of where the name is actually used.

Completeness

Calculated from how many of the expected data sections (variants, similar names, popularity, notable usage, IPA pronunciation) are actually populated for this name.

Direct observation vs. inference

Averaged from the real per-claim direct-observation-vs-inference ratios already computed for this name's evidence.

Identity & variant resolution quality

Cross-source identity and variant resolution requires HEKNO Knowledge, which isn't connected yet.

Name Characteristics

How these are calculated

Descriptive attributes of the name itself — not a confidence measurement, and not an overall quality score. Namewise doesn't approve or disapprove of names.

Pronunciation clarity

Editorial judgement of how consistently this name is pronounced correctly on first read, mapped from an easy/moderate/variable rating to a number. Describes the name — not a measure of evidence confidence.

Spelling simplicity

Calculated directly from the name's spelling: shorter names with fewer irregular letter clusters score higher. A disclosed formula, not an editorial opinion — and not a confidence measurement.

Recorded regional spread

Derived from how many geographies' official statistics record this name. It measures where the name is registered, not how well-known it feels to people living there.

International spread

Derived from the same official statistical coverage, scaled to reflect how widely the name crosses national datasets. Not a measure of how easily it is understood in another language.

Trend stability

Derived from the name's traditional/modern classification and its current popularity trend direction.

Jason across 6 official records

Each registrar publishes its own list, so these figures are read down a row, never across one. A position in one country is not comparable with a position in another, and Namewise never combines them into a single ranking. The birth counts do not compare across rows either, for a different reason: England and Wales registers roughly thirty times as many births a year as Northern Ireland, so a larger total says which registrar recorded it as much as how widely the name was given.

Jason by decade in Republic of Ireland · Boys

Births registered with the name in each decade of this one list, with the number of years the list covers in that decade. Bars are scaled on births a year, which is the figure that compares between decades — a decade the list only partly covers has a smaller total without being a quieter decade. Figures belong to this registrar alone and do not carry to another.

Jason appears in

Groupings this name qualifies for under their own stated rules, from the same official statistics shown above.

What the record shows

Recorded by 7 registrars between 1964 and 2025, ranked in 62 years of that period.

Its highest recorded position is #1, first reached in 1970.

It held a top-100 place in 51 years, 50 of them consecutive.

Its largest count from any one registrar is 2,304 births, registered in New South Wales, Australia in 1972.

2 registrars ranked it inside their own top 10. It reached #1 in 2 registrars' lists.

A second registrar first ranked it in 1965, and 60 years separate the first registrar to record it from the last.

Every figure here is counted from the seven official registrars Namewise holds. A position is only ever a place within the list that published it, and a record that thins or stops is a fact about what registrars printed — never about how many children received the name.

Jason was ranked #1 in New South Wales, Australia · Boys in 1971. These are the names immediately either side of it on that published list — a fact about the registrar's own output, not a similarity judgement.
