Workforce diversity
Gender ratio
Gender ratio measures the proportion of employees by gender across an organisation or within specific teams, levels, and functions. It is a foundational diversity metric that reveals structural imbalances in representation and informs targeted interventions to build a more balanced workforce.

What is gender ratio?
Gender ratio is the percentage of the workforce represented by each gender. The most common expression is the percentage of female employees, though a comprehensive view includes all gender identities that employees choose to disclose. The metric is typically reported as an overall figure (e.g. 42% female) and segmented by department, job level, function, and geography.
The overall ratio tells part of the story, but segmented analysis reveals the structure beneath it. An organisation with a 50:50 overall split may still have severe imbalances: 80% male in engineering, 85% female in HR, 90% male in senior leadership. These patterns reflect occupational segregation and progression barriers that the headline number obscures.
Gender ratio matters for several reasons. Research consistently shows that gender-diverse teams make better decisions, are more innovative, and deliver stronger financial performance. McKinsey's "Diversity Wins" research found that companies in the top quartile for gender diversity on executive teams were 25% more likely to achieve above-average profitability. Beyond performance, gender balance is increasingly a factor in talent attraction: candidates, particularly younger professionals, evaluate prospective employers on their diversity credentials.
The metric is also a prerequisite for other equity analyses. You cannot measure the gender pay gap, gendered promotion rates, or gendered attrition patterns without first understanding your gender ratio at each level and function. It is the foundation upon which all other gender equity metrics are built.
Overall gender ratio is a starting point, not an endpoint. The most valuable insights come from segmenting by level, function, and tenure to understand where representation is strong, where it drops off, and at which career stage imbalances emerge.
How to measure gender ratio
Express gender ratio as the percentage of total employees who identify as each gender. For binary reporting, this is typically the percentage of female employees (with male as the complement). Inclusive measurement also reports the percentage of employees who identify as non-binary or who prefer not to disclose.
For meaningful analysis, calculate the ratio at multiple levels: overall, by department, by job level (individual contributor, manager, director, VP, C-suite), by function (engineering, sales, marketing, operations), and by geography. Track these ratios over time to identify trends and measure the impact of diversity initiatives.
| Segmentation | What it reveals | Example insight |
|---|---|---|
| By job level | Progression pipeline health | 45% female at entry level but 18% at director level indicates a "leaky pipeline" |
| By department | Occupational segregation patterns | 12% female in engineering but 78% in people operations shows function-level imbalance |
| By tenure band | Retention equity | Female representation declining in longer tenure bands suggests higher female attrition |
| By hiring cohort | Recruitment progress | Recent cohorts showing higher female representation indicates improving hiring practices |
Decomposing gender ratio with a metric tree
A metric tree breaks the overall gender ratio into the factors that shape it, revealing whether imbalances are driven by hiring, progression, retention, or structural workforce composition.
This tree isolates where gender imbalances originate. If your applicant pool is 50:50 but your hires are 70:30, the issue is in your selection process: interview bias, assessment design, or offer competitiveness may be filtering women out at higher rates. If your hires are balanced but your senior leadership is not, the issue is in progression: women are either not being promoted at the same rate, not staying long enough to reach senior levels, or both.
Return-from-leave retention is a particularly important node. If women who take maternity or parental leave return at lower rates or leave within 12 months of returning, there is a structural barrier that no amount of recruitment will overcome. The tree makes this visible and measurable.
Gender ratio benchmarks
| Segment | Typical female representation | Context |
|---|---|---|
| Overall workforce (UK) | 47% to 50% | UK labour market participation is near parity. Organisations significantly below this should investigate root causes. |
| Technology (overall) | 25% to 35% | Lower female representation driven by engineering roles. Non-technical functions are often at or above parity. |
| Technology (engineering) | 15% to 25% | Persistent pipeline challenge from education through industry. Improving but slowly. |
| Financial services | 40% to 50% | Near parity overall, but significant gaps in senior and investment roles. |
| Senior leadership (cross-industry) | 25% to 35% | The most persistent gap. Female representation drops sharply above director level in most industries. |
| Board of directors (FTSE 350) | 38% to 42% | Significant improvement driven by the FTSE Women Leaders Review targets, up from 12% in 2011. |
Gender ratio targets should reflect the available talent pool for each function, not an arbitrary 50:50 split. For engineering roles where the graduate pipeline is 25% female, a 25% target is a more meaningful benchmark than 50%. The goal is to hire and retain your fair share of the available talent.
Strategies to improve gender balance
- 1
Set specific, measurable representation targets
Define targets for female representation at each level and function, benchmarked against the available talent pool. Track progress quarterly and publish results internally. Accountability drives action; vague commitments to "improve diversity" do not.
- 2
Address the hiring pipeline at every stage
Track gender ratio at each stage of the hiring funnel: applicants, phone screens, interviews, offers, and acceptances. Identify where female candidates drop off at higher rates and investigate the causes. Diverse shortlists, structured interviews, and bias training for interviewers help close conversion gaps.
- 3
Fix the progression pipeline
Analyse promotion rates and time-to-promotion by gender. If women are promoted less frequently or take longer to reach the same level, investigate whether sponsorship, visibility, and stretch assignment distribution are equitable. Build formal sponsorship programmes to ensure high-potential women have senior advocates.
- 4
Improve retention of women at critical career stages
The mid-career stage, often coinciding with family formation, is where female attrition is highest. Enhanced parental leave, phased return-to-work programmes, flexible working at senior levels, and proactive stay interviews for women in the mid-career cohort reduce preventable departures. Monitoring employee turnover rate by gender highlights where retention interventions are most needed.
- 5
Create inclusive culture and role models
Representation at senior levels creates a visible signal that progression is possible. Highlight female leaders, ensure women are represented on interview panels and decision-making bodies, and address cultural factors like meeting dynamics and communication norms that can marginalise under-represented groups.
Tracking gender ratio with KPI Tree
KPI Tree lets you model gender ratio as a multi-dimensional metric tree that connects representation data to the hiring, progression, and retention factors that drive it. You can track the ratio by level, function, tenure, and geography, and connect it to related metrics like the gender pay gap, promotion rates, and employee engagement scores.
The tree turns gender ratio from a static annual report into a live operating metric. When representation drops in a specific segment, the tree shows whether the cause is hiring shortfall, promotion gap, or elevated attrition, guiding the appropriate intervention.
Each branch can be owned by the relevant stakeholder: talent acquisition owns the hiring pipeline, department heads own their team composition, and leadership development owns the progression pipeline. This distributed accountability ensures that improving gender balance is treated as an organisational priority at every level.

Employee turnover rate
Staff attrition
HR & People MetricsMetric Definition
Turnover Rate = (Separations / Average Headcount) × 100
Employee turnover rate measures the percentage of employees who leave an organisation during a given period. It is one of the most closely watched HR metrics because high turnover disrupts productivity, erodes institutional knowledge, and drives up recruitment and training costs.
Employee retention rate
Workforce stability
HR & People MetricsMetric Definition
Retention Rate = ((Ending Headcount − New Hires) / Beginning Headcount) × 100
Employee retention rate measures the percentage of employees who remain with the organisation over a given period. It is the positive counterpart to turnover rate and reflects the effectiveness of the organisation's employee value proposition, management quality, and culture.
Cost per hire
Recruiting efficiency
HR & People MetricsMetric Definition
Cost per Hire = (Internal Recruiting Costs + External Recruiting Costs) / Total Hires
Cost per hire measures the total expense incurred to fill a single position, including both internal recruiting costs and external spending. It is the primary financial efficiency metric for the talent acquisition function.
Employee net promoter score
