Board female-to-male member ratio

Measurement answer

What this metric measures

Source-reported average ratio of female to male board members for the exact EU reporting scope and period, retaining the averaging method, board population, gender-category treatment and zero-or-unknown male-denominator state.

Specification

Result format
Multi-field profile
Unit
Female board members per male board member (ratio)
Reporting basis
Source-reported measurement date or averaging period
Aggregation
Ratios are non-additive and are never averaged; cross-body calculation requires compatible raw quantities and a separately admitted weighting method.

Reporting boundary

A measurement-date female count divided by a male count is not automatically the source’s average ratio. The ratio is not converted into a female share or percentage.

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.

Value structure

Dimensions and units

Unit

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.

Method disclosures required

Source-edition basis: Commission Delegated Regulation (EU) 2023/2772, consolidated 1 January 2025 — Consolidated 1 January 2025 edition. Retain the exact source edition on every observation; later editions require a separate method profile.

  • Reporting undertaking and boundary.
  • Board population and system.
  • Person or membership basis.
  • Female-category definition.
  • Male-category definition.
  • Nonbinary, other and undisclosed treatment.
  • Measurement date or averaging period.
  • Averaging level and weighting.
  • Retain the exact measurement-source edition with every observation.
  • The source-reported ratio retains its female numerator, male denominator, board population, averaging basis and treatment of other, undisclosed and zero-denominator states.

Record-specific limitations

  • A binary ratio does not represent all gender identities.
  • The ratio can be undefined when the male quantity is zero.
  • Unknown categories can be obscured.
  • Reported composition does not measure inclusion, equality, influence or effectiveness.

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.
