Most organisations today would say they care about diversity in leadership, and they are not wrong. Many have targets, policies, and public commitments. Leadership statements talk about inclusion, equal opportunity, and fairness. Corporate websites proudly display representation goals. Diversity is no longer a fringe topic. It is present in strategies, reports, and conversations. And yet, when you look closely at leadership composition and progression patterns, a quieter question emerges: Are we still overlooking a growing diversity gap, even as awareness increases? The data suggests that we might be.
We often begin with gender because it is the most consistently measured dimension. And the quantitative story here is stark.
According to the most recent Women in the Workplace report from McKinsey & Company and LeanIn.Org, the largest drop-off for women happens at the first step into management. In 2025, for every 100 men promoted to manager-level roles, only 93 women are promoted, and the gap is wider for women of colour. As organisations ascend the hierarchy, the representation of women continues to decline, resulting in only about 29% of C-suite roles being held by women and even fewer by women of colour.
This pattern, known in diversity research as the “broken rung”, has persisted over more than a decade and shows up across industries and regions. The consequence is cumulative: fewer women at the entry-level leadership step means fewer women available to progress further up the organisational ladder.
Even in organisations that affirm diversity verbally, this early gap quietly magnifies over time.
The gap extends beyond gender
But gender tells only part of the story. Leadership exclusion happens along multiple dimensions, and the dynamics are interconnected.
LGBTQ+ professionals face hidden barriers
There is less quantitative data on LGBTQ+ representation at senior leadership levels than there is on gender, but the available research indicates persistent challenges.
Research on psychological safety and marginalisation among LGBTQIAPN+ professionals shows that a lack of psychological safety, the sense of being able to be one’s authentic self without fear of negative consequences, can affect people’s willingness to pursue leadership opportunities. LGBTQ+ employees often experience marginalisation, microaggressions, exclusion, or pressure to conform to norms that align with heterosexual or cisgender expectations.
Separate studies exploring long-term career progression among 2SLGBTQIA+ professionals consistently report that discrimination, lack of inclusive sponsorship, and a need to navigate unsafe work environments slow or divert career trajectories, even when individuals are capable, motivated, and talented.
While specific promotion-rate figures for LGBTQ+ people are scarce, these qualitative and survey-based insights reveal something critical: even with progressive policies on paper, the lived experience of inclusion, especially at early stages of career growth, is uneven at best.
People with disabilities experience structural exclusion
People with disabilities and chronic health conditions represent one of the largest minority groups worldwide, an estimated 17% of the global population. Despite this scale, disability inclusion remains underprioritised in leadership pipelines.
Deloitte’s Disability Inclusion @ Work 2024 report, a global survey of more than 10,000 respondents across 20 countries, highlights key workplace inclusion gaps that affect career progression. A majority of employees with disabilities report that they have faced barriers to workplace participation, including high rates of requested accommodations being rejected, poor accessibility at work events, and non-inclusive behaviours.
These barriers do not just affect day-to-day work. They shape perceptions of readiness, confidence in career planning, and organisational signals about who is seen as leadership material.
Immigrant and migrant professionals: Another invisible barrier
Data on immigrant and migrant professionals in leadership is less systematically collected, but existing diversity research, including analyses from cross-national studies, shows a consistent pattern: foreign-born and migrant employees are often well-represented in the workforce but underrepresented in leadership roles. A range of invisible barriers, from accent bias and cultural norms about communication styles to weaker informal networks and lower access to internal sponsorship, continue to shape advancement outcomes in subtle ways.
These patterns echo familiar dynamics: when formal criteria are present but informal access structures such as network visibility, advocacy, and trust are not equally available, leadership outcomes are inequitable.
Why do early leadership transitions matter the most?
What connects these patterns, gender gaps, LGBTQ+ progression challenges, disability inclusion barriers, and underrepresentation among migrant professionals is not a lack of ambition, talent, or aspiration. It is how leadership systems function in practice.
Leadership progression is rarely driven by objective performance metrics alone. Performance matters, but it is only one part of a much larger ecosystem. Careers are shaped by:
- Early trust and visibility
- Informal sponsorship and advocacy
- Exposure to decision-makers and strategic work
- Opportunities to try, fail, learn, and be seen doing so
These mechanisms shape whether someone feels legitimate and ready for more responsibility. Crucially, when these mechanisms operate informally, through relationships, instinct, or intuition, they tend to favour familiarity.
This familiarity often aligns with historically advantaged profiles: people who look like existing leaders, speak like them, and come through similar networks. Over time, a consistent pattern of selection emerges, even in organisations that believe they are operating on merit.
This is why the leadership diversity gap is easy to overlook.
- It does not always show up as an explicit exclusion.
- It shows up as repetition.
- The same types of profiles are being promoted.
- The same leadership styles are rewarded.
- The same narrative of “readiness” and “fit” is used to justify outcomes.
On paper, nothing looks discriminatory. In reality, the system quietly selects familiarity again and again.
This is not primarily a values problem; it’s a system design problem. From my perspective, the root issue is not a lack of values.
Most leaders do not consciously sit down and decide to exclude people. Many care sincerely about fairness, equality, and inclusion. Many believe they are creating opportunity.
The problem is the design of how leadership pathways are structured, enabled, and evaluated.
When leadership systems rely heavily on subjective judgments, informal networks, and unexamined assumptions about readiness, inequality reproduces itself quietly. Without intentional design, bias will follow the path of least resistance, and that path often favours those who resemble existing leaders.
Design matters because it affects behaviour, and behaviour shapes outcomes.
The real cost of overlooking the gap
The risk of overlooking this growing diversity gap is not only reputational. It is operational.
Organisations that lose capable talent early do not feel the impact immediately. In the short term, work gets done. Deadlines are met. Teams function. But the real cost shows up later:
- Thinner leadership benches
- Reduced organisational resilience
- Lower innovation due to homogeneous perspectives
- Higher turnover as excluded talent exits
- A disconnect between leadership and the workforce it serves
An organisation that fails to cultivate diverse leadership is, by definition, narrowing the viewpoints, lived experiences, and problem-solving lenses at the heart of its decision-making.
A quiet problem requires conscious attention
The leadership diversity gap is not always loud. It does not always produce crisis headlines. It does not often show up in simplified metrics like headcount alone.
It sits in everyday decisions that are taken with good intent, under time pressure, within familiar systems.
It lives in:
- Who gets early trust
- Who gets stretch assignments
- Who is introduced to decision-makers
- Who is mentored and sponsored
- Who is seen as “leadership material” early on
Recognising this gap is not about assigning blame. It is about acknowledging how leadership systems shape outcomes, consciously or not. Leadership outcomes are not accidental. They are designed.
If we want leadership to reflect the world it serves
Then we must focus not only on the top but on the beginnings:
- Early promotion decisions
- Transparent and structured leadership criteria
- Equitable access to sponsorship and development
- Data that tracks progression across multiple dimensions
- Systems that prioritise inclusion as a lived practice, not a statement
Because leadership diversity does not begin at the top.
It begins much earlier, at the first opportunity to lead others, to be seen, and to be trusted.
If we want the future of leadership to be genuinely inclusive, sustainable, and reflective of the world it is meant to serve, our attention must shift upstream.
Not to the loudest places.
But to the quiet, everyday structures that shape who gets seen, who gets trusted, and who gets to lead.
About EQUAIS
EQUAIS works with organisations to strengthen leadership systems so that access, progression, and opportunity are designed intentionally rather than left to habit. The focus is not on awareness, but on how leadership decisions are made in practice: from first-time management transitions and sponsorship patterns to decision consistency and leadership behaviours under pressure. The aim is to help organisations build leadership structures that support long-term performance while widening who can progress within them.
