Median hourly gender pay gap by declared method

Measurement answer

What this metric measures

Signed percentage difference between source-method median male and female hourly pay for the declared eligible employee populations, retained with the jurisdiction, legal entity, snapshot date, pay components, source-native category definitions and method edition.

Reporting boundary

Gaps and medians are never summed or averaged. Each legal entity is reported separately. Consolidation or roll-up requires employee-level hourly pay observations and a separately admitted method. Mean, median-hourly and median-bonus gaps remain separate.

Cross-library identity

Library mappings and variants

These links compare quantity, population, boundary, period, unit, denominator, aggregation, dimensions, and method edition. Partial relationships are navigation aids only and never authorize observation reuse.

Verified sources

Evidence and status sources

Sustopedia checked each record-specific claim directly against primary publisher material. Labels distinguish current measurement authority from future compatibility and corroborative, legal, edition, or method status context. Corroborative evidence can support a stated limitation but cannot establish the core measurement by itself.

Source-edition basis: Equality Act 2010 (Gender Pay Gap Information) Regulations 2017, original official PDF — 2017 edition; GOV.UK gender pay gap guidance - making calculations — Edition identified in the official source title. Retain the exact source edition on every observation; later editions require a separate method profile.

  • Source-method profile and edition.
  • England, Scotland or Wales applicability.
  • Private or voluntary legal entity.
  • 5 April snapshot date.
  • Relevant pay period.
  • Eligible and full-pay- eligible employee counts by source-native male and female sex category.
  • Leave-reduced-pay exclusion.
  • Ordinary and bonus pay treatments.
  • Retain the exact measurement-source edition with every observation.
  • A signed percentage under a named jurisdictional method; a negative result reverses the usual direction and the underlying hourly pay values retain their currency and pay boundary.

Record-specific limitations

  • An unadjusted median gap does not establish equal pay for equal work or identify the cause of a difference. Occupational mix, part-time patterns, leave exclusions and pay structures affect the result. Binary source-native legal categories do not describe all gender identities and must not be extended or inferred. Small groups can create privacy and volatility concerns.

Interpret this metric with the stated reporting boundary, period convention, value shape, and unit. Results prepared with different boundaries or conventions may not be directly comparable.

Measurement evidence supports the core record-specific claims described above. Corroborative evidence can support limitations, while compatibility and status sources provide their separately labelled context. None of these cards by itself determines an organisation's legal applicability, filing readiness, assurance status, or compliance conclusion.
