Understanding Gender Pay Gap vs. Pay Equity: Key Differences and Implications

Executive Summary

The terms "gender pay gap" and "pay equity" are frequently confused, yet they represent fundamentally different concepts with different measurement approaches, legal implications, and remediation strategies. This guide clarifies these distinctions and explains why both matter for organizations committed to fair compensation.

Defining the Terms

Gender Pay Gap

The gender pay gap is a high-level statistical measure comparing the average or median earnings of all women in an organization (or economy) to all men, expressed as a percentage difference.

Formula:

Gender Pay Gap (%) = [(Male Average Pay - Female Average Pay) / Male Average Pay] × 100

Example: If men earn an average of $75,000 and women earn $60,000:

[(75,000 - 60,000) / 75,000] × 100 = 20% gender pay gap

Pay Equity

Pay equity (also called equal pay or pay fairness) is the principle and practice of ensuring individuals receive equal compensation for work of equal or comparable value, controlling for legitimate factors like experience, performance, education, and job responsibilities.

Pay equity analysis uses statistical methods (typically multivariate regression) to identify unjustified pay differences between demographic groups performing similar work.

Key Differences

1. What They Measure

Gender Pay Gap:

• Compares ALL women to ALL men across entire organization
• Does not account for job types, seniority, experience, or other factors
• Shows overall representation and pay distribution
• Answers: "How do women's average earnings compare to men's?"

Pay Equity:

• Compares individuals in same or similar roles
• Controls for legitimate pay factors (experience, performance, education)
• Identifies unexplained differences that may indicate discrimination
• Answers: "Are people paid fairly for the work they do?"

2. Causes

Gender Pay Gap Caused By:

• Occupational segregation (women in lower-paying roles/industries)
• Vertical segregation (women underrepresented in senior positions)
• Part-time work differences
• Career interruptions and caregiving responsibilities
• Industry and sector differences
• Plus: any pay inequity within roles

Pay Equity Issues Caused By:

• Discriminatory pay-setting practices
• Biased salary negotiations
• Unequal starting salaries
• Inequitable raises and bonuses
• Performance evaluation bias
• Promotion disparities

3. Can You Have One Without the Other?

Yes - Common Scenarios:

Scenario A: Large Gender Pay Gap, No Pay Equity Problem

• Organization has equal pay for equal work
• But women concentrated in lower-paying roles
• Structural/representation issue, not discrimination in pay-setting
• Solution: Focus on promotion, hiring, and career development

Scenario B: Small Gender Pay Gap, Pay Equity Problems

• Similar representation of women/men across levels
• But women systematically paid 5-10% less within same roles
• Pay discrimination masked by balanced representation
• Solution: Immediate pay adjustments and process fixes

Scenario C: Both Problems

• Women underrepresented in senior roles AND
• Paid less than men in same positions
• Most common and most serious scenario
• Solution: Comprehensive strategy addressing both issues

Measurement Methodologies

Measuring Gender Pay Gap

Simple Method:

1. Calculate average or median pay for all women
2. Calculate average or median pay for all men
3. Compute percentage difference

Enhanced Reporting (e.g., UK Gender Pay Gap):

• Median pay gap
• Mean pay gap
• Median bonus gap
• Mean bonus gap
• Percentage receiving bonuses
• Quartile distribution (% women in each pay quarter)

Advantages:

• Simple to calculate
• Easy to understand
• Good for transparency and benchmarking
• Highlights representation issues

Limitations:

• Doesn't prove or disprove discrimination
• Heavily influenced by workforce composition
• Can't identify where problems exist
• Doesn't control for legitimate factors

Measuring Pay Equity

Regression Analysis Method:

1. Gather comprehensive data on all employees
2. Include pay and legitimate factors (job level, tenure, performance, education, location)
3. Run multivariate regression analysis
4. Identify statistically significant unexplained gaps
5. Flag individuals potentially affected

Variables Typically Controlled:

• Job family/function
• Job level/grade
• Years of experience
• Performance ratings
• Education level
• Geographic location
• Full-time vs. part-time status

Output:

• Adjusted pay gap percentage
• Statistical significance (p-value)
• Number of affected employees
• Dollar amount of remediation needed
• Identification of problematic jobs/departments

Advantages:

• Legally defensible methodology
• Identifies specific discrimination
• Enables targeted remediation
• Controls for legitimate factors

Limitations:

• Complex and requires expertise
• Data quality dependent
• May miss discrimination embedded in "legitimate" factors
• Expensive to conduct properly

Regulatory Approaches

Gender Pay Gap Reporting

Countries/Jurisdictions:

• United Kingdom (250+ employees)
• France (as part of Index calculation)
• Australia (100+ employees, expanding)
• Japan (300+ employees)
• EU Directive (100+ employees by 2027)

Requirements:

• Annual reporting to government
• Public disclosure
• Often requires narrative explanation
• May require action plans

No Remediation Mandate in most jurisdictions:

• Organizations must report gaps
• But no legal requirement to close them
• Relies on transparency creating pressure

Pay Equity Laws

Countries/Jurisdictions:

• Iceland (certification requirement)
• California (pay data reporting)
• Ontario, Canada (pay transparency act)
• EU Directive (includes equity provisions)

Requirements:

• Conduct statistical analysis
• Identify unjustified gaps
• Remediate gaps within specified timeframes
• May require third-party audits
• Document compliance

Remediation Mandatory:

• Organizations must fix identified problems
• Back pay may be required
• Failure to remediate = violations

Real-World Examples

Example 1: Tech Company

Gender Pay Gap: 35% (Women earn 35% less on average)

Analysis:

• Women concentrated in marketing, HR, operations (lower-paid)
• Men dominate engineering, product management (higher-paid)
• Very few women in executive leadership

Pay Equity Audit Results: No significant pay inequity within roles

• Female engineers paid 98% of male engineers (not statistically significant)
• Female product managers paid 101% of male product managers
• Representation problem, not pay discrimination problem

Solution Strategy:

• Increase women in technical roles (hiring, development)
• Create pathways for women to move into product/engineering
• Mentorship and sponsorship programs for leadership pipeline
• No immediate pay adjustments needed

Example 2: Financial Services Firm

Gender Pay Gap: 12% (relatively small)

Analysis:

• Good representation of women across most levels
• Balanced workforce composition

Pay Equity Audit Results: 8% unexplained gap favoring men

• Women systematically paid less at hire (negotiation gap)
• Smaller raises and bonuses over time
• Issue exists across multiple departments and levels

Solution Strategy:

• Immediate pay adjustments for affected women ($2.3M remediation)
• Standardize starting salary offers (remove negotiation bias)
• Audit raise and bonus processes
• Train managers on bias-free decisions
• Annual monitoring

Example 3: Manufacturing Company

Gender Pay Gap: 28%

Pay Equity Audit Results: 6% unexplained gap

Analysis:

• Both problems: Representation + pay discrimination
• Women underrepresented in management (gap driver)
• AND paid less within same roles (equity problem)

Solution Strategy:

• Immediate pay adjustments ($800K)
• Promotion process reform
• Targeted hiring for senior roles
• Manager training on equitable decisions
• Multi-year action plan for representation
• Quarterly monitoring

Why Both Matter

Gender Pay Gap Matters For:

Transparency and Accountability

• Simple metric that stakeholders understand
• Creates public pressure for change
• Enables benchmarking and tracking

Representation Issues

• Highlights structural barriers to advancement
• Shows effectiveness of diversity initiatives
• Reveals occupational segregation

External Communication

• Investors increasingly focus on gap metrics
• Customers and candidates care about fairness
• Industry comparisons

Pay Equity Matters For:

Legal Compliance

• Directly addresses discrimination laws
• Required in growing number of jurisdictions
• Provides litigation defense

Employee Trust

• Directly impacts individual employees
• Demonstrates commitment to fairness
• Builds confidence in pay processes

Immediate Fairness

• Fixes actual discrimination
• Ensures current employees paid fairly
• Provides tangible remedies

Common Mistakes

Mistake 1: Confusing the Metrics

Problem: "We don't have a pay equity problem because our gender pay gap is only 10%" Reality: A 10% gap could indicate serious pay discrimination depending on workforce composition

Mistake 2: Ignoring the Gap Because Equity is Good

Problem: "Our pay equity audit was clean, so we don't need to address our 30% gender pay gap" Reality: Large representation gaps are still problematic and require attention

Mistake 3: Only Looking at Averages

Problem: "Our average pay for women and men is similar" Reality: May mask pockets of serious discrimination in specific departments or levels

Mistake 4: Assuming Legitimate Factors Are Actually Legitimate

Problem: "Women get smaller raises because their performance ratings are lower" Reality: Performance ratings themselves may be biased - need to examine the entire system

Mistake 5: Treating as One-Time Exercise

Problem: "We did an audit three years ago and fixed the gaps" Reality: New inequities emerge through ongoing hiring and promotion - continuous monitoring essential

Recommended Approach: Address Both

Integrated Strategy

Annual Cycle:

Q1: Gender pay gap reporting and disclosure

Conclusion

Understanding the distinction between gender pay gap and pay equity is essential for effective action:

• Gender pay gap shows the overall picture and representation challenges
• Pay equity identifies and fixes discrimination in pay-setting
• Both matter and require different approaches
• Integrated strategies addressing representation and fair pay deliver best results
• Continuous monitoring is essential as both can emerge over time

Organizations should measure and address both metrics, communicate transparently about the differences, and implement comprehensive programs that ensure fair pay today while building diverse representation for tomorrow.
