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.
Specification
Metric specification
- Result format
- Structured table
- Unit
- Median hourly gender pay gap (%)
- Reporting basis
- Reporting period or measurement date declared by the source method
- Aggregation
- Do not sum or arithmetically average reported percentages, rates, ratios, or averages; consolidate only from compatible component observations under a disclosed method.
- Pillar
- Social
- Topic
- Pay, wages and labor relations
- Controlled domain
- Workforce
- Entity type
- Metric
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.

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.

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.
