Board diversity
Definition
The degree to which a board of directors comprises members who differ from one another across dimensions such as gender, ethnicity, age, skills, professional experience, education and other identity and cognitive characteristics. The objective is a less homogenous board capable of evaluating information and decisions from diverse perspectives in the interests of all stakeholders.

Overview
What it means
Board diversity is a core ESG "G" metric: it is measured through demographic disclosure (gender and ethnicity most commonly), governed by board diversity policies and statements, and driven by investor pressure, listing rules (for example Nasdaq's board-diversity disclosure framework) and legislation in several jurisdictions.
Research links diverse boards to stronger decision quality and innovation outcomes, though causality and measurement remain debated. Reporting can be complicated by directors' reluctance to self-identify ethnicity or sexual orientation.
How it is used
Companies publish board-diversity matrices and targets; investors vote against homogenous nomination committees; regulators set disclosure or quota requirements. In sustainability reporting standards, board composition diversity is a standing disclosure item.
Why it matters
Boards set the tone for organisational equity: homogeneous boards correlate with groupthink and blind spots on social issues, making board diversity a leading indicator of whether inclusion commitments reach the top.
