| Measure or finding | What it shows | Planning use |
|---|---|---|
| 77-cent headline (unadjusted gap) | A comparison of the gross income of all women with all men, with no adjustment for job or hours | Treat it as a starting signal about average earnings, not proof that one employer underpays one woman |
| Adjusted comparison | Looks at what the headline leaves out: education, experience and comparing people in the same career | Use the same checklist when you judge whether an offer is fair for your role |
| Country spread | Women in Australia, Belgium, Italy and Sweden earn about 80% of male earnings; in Austria, Canada and Japan about 60% | Look up your own country’s statistics before benchmarking yourself against a foreign figure |
| Fertility link | The gap is positively associated with the fertility rate in a cross-country study | Negotiate leave, return-to-work and progression terms early, not after a career break starts |
| Collective bargaining | Negatively associated with the gap in the same body of research | Ask whether pay scales are collectively agreed or published |
Figures: the gross-income definition comes from an Independent Institute op-ed, and the country and association findings from a cross-country study of OECD wage data.
The gender pay gap myth claim is half right: the famous headline figure is a raw comparison that ignores job and experience, yet a measured earnings difference between women and men is real and its causes can be tested.
If you are weighing a career move or a new venture, the same pay questions sit alongside funding choices such as business grants for women in our careers hub.
What the headline figure means for your decisions
The most useful way to read the debate is as two separate questions: what the raw number measures, and how much of it remains once like is compared with like. Each answer changes what you should do next.
- Read the headline as an average, not a verdict on your employer. The 77-cent comparison sets the gross income of all women against all men, according to the Independent Institute op-ed. It cannot tell you whether the person next to you in the same job is paid more.
- Collect like-for-like evidence before you act. The critics’ own objection, that the figure ignores education, experience and working in the same career, doubles as a benchmarking checklist. Your job title, qualifications and years of relevant experience are the facts that make a comparison fair.
- Do not dismiss the gap because the headline is crude. A flawed headline does not erase a difference in earnings that appears in country-level data, and the decisions that follow from a real difference (negotiating, asking about pay structures, planning leave) are worth making either way.
- Treat location as a variable. Cross-country comparisons show large spreads, so a figure quoted for one country is a poor guide to pay in another.
To use those decisions well, it helps to know exactly how the two measures differ.
Adjusted versus unadjusted pay gap
The unadjusted pay gap is the plain difference between women’s and men’s earnings across the whole workforce, while the adjusted pay gap tries to compare people who are alike in measurable ways. That distinction is where most of the myth argument lives.
The unadjusted figure is a comparison of gross income. According to the Independent Institute op-ed, it fails to take into account factors such as education, experience, or even comparing people in the same career. That is a fair description of what the 77-cent number is and is not. It is a population-level average, and it mixes together every reason women and men might earn different amounts, from the jobs they hold to how they are treated within those jobs.
The adjusted measure removes some of that mixture by controlling for the variables the critics name. It answers a narrower question: for people with similar qualifications, experience and role, is there still a difference? Two cautions apply to any adjusted number. It depends entirely on which variables the researcher includes, so leaving out a relevant factor can mislead. And if a control itself reflects unequal treatment, such as which roles women are steered towards, adjusting for it can hide part of the disadvantage. Neither measure is the “true” gap; each answers a different question.

The same logic extends beyond one workplace, which is how country comparisons come into play.
How large is the pay gap in different countries?
The size of the gap varies a great deal between OECD countries. One cross-country study found that women in Australia, Belgium, Italy and Sweden earn about 80% as much as men, while in Austria, Canada and Japan women earn about 60%. The study drew on OECD wage data for 35 countries covering 1970-2002.
Those results are best used as a picture of how widely countries can differ, not as current rates. The study’s data period ends in 2002, and the earnings ratios it reports are unadjusted comparisons rather than like-for-like ones. Interestingly, the grouping does not follow an obvious pattern: Sweden and Italy sit together at one level, and Canada and Austria together at another, which suggests national institutions and labour-market structure matter more than a simple rich-versus-poor divide.
For a decision you are making now, such as negotiating, relocating or comparing multinational employers, take the latest unadjusted and adjusted figures from your own country’s national statistics office or the OECD, and use the 80% and 60% groupings only as context for how much the answer can change by location.
What causes the pay gap?
No single factor explains the gap. The research supplied here points to several drivers, each of which suggests a different response.
Motherhood and career breaks
The motherhood penalty is the term for the earnings disadvantage that follows parenthood, which falls mainly on mothers. In the cross-country study, the gender pay gap is positively associated with the fertility rate, meaning countries with higher fertility tend to show larger gaps. That is an association between countries, not proof about any individual mother, but it fits the idea that caring responsibilities and career interruptions shape pay.

Marriage patterns
The same study reports that the gap is positively associated with the husband-wife age gap at first marriage. The finding shows that household structure, not only workplace practice, is linked to pay differences across countries. It is context rather than something an individual can act on directly.
Occupation, hours and experience
These are the factors critics emphasise when they call the headline misleading, and they are the variables an adjusted comparison controls for. They matter, but whether they account for all of a gap depends on which controls a study includes and whether those controls themselves reflect unequal opportunity.
Pay-setting institutions
On the employer side, the study notes that collective bargaining, as found in previous studies, is negatively associated with the gender pay gap. Where pay scales are negotiated collectively, gaps tend to be smaller, which points to structured, transparent pay-setting as a lever.
Salary negotiation and employer action
Each driver above suggests something you can do, though individual action cannot fix every structural cause.
- Negotiate with a role-based case. Because the adjusted comparison turns on education, experience and role, build your ask around those facts: your qualifications, your years of relevant experience and the scope of the job. Ask for the pay band if one exists, name a figure and give the reason for it.
- Negotiate the terms around pay too. Given the link between parenthood and the gap, agree leave, flexibility and return-to-work arrangements in writing before you need them, and revisit pay at each review rather than only at hiring.
- Look for structured pay. If collectively agreed or published scales are associated with smaller gaps, prefer employers that publish bands or explain how raises are decided.
- Practise the conversation. Hearing how others handle it helps, and the shows in Women In Business Podcasts: 10 Must-Listen Shows To Boost Your Career In 2026 – Platformwomen are one way to do that. For structured one-to-one support rehearsing an ask or pricing your own work, see Business Coach For Women Entrepreneurs: Build Profitable, Purpose-Driven Businesses In 2026 – Platformwomen.
Employers who want to narrow their own gap can start with the same levers: publish pay bands, set clear criteria for raises and promotions, and agree flexible-leave terms openly rather than case by case.
Frequently asked questions
Is the 77-cent figure wrong?
It is accurate as a description of what it compares, the gross income of all women with all men, but it makes no adjustment for education, experience or same-career comparison, so it overstates what it can prove about pay for equal work.
Can I treat the country percentages as current pay-gap rates?
No. They come from a study using OECD wage data for 35 countries covering 1970-2002, and they are unadjusted comparisons. Use them to see how widely countries differ, then check your own country’s latest statistics through its national statistics office or the OECD.
Does having children lower a woman’s pay?
The cross-country evidence shows that gaps tend to be larger where the fertility rate is higher, an association rather than proof about any one woman. The practical response is to settle leave and return terms early and to keep pay under review afterwards.
What can employers do to reduce the gap?
Collective bargaining is associated with smaller gaps, so structured, transparent pay-setting is the best-supported direction. Published pay bands and clear raise criteria follow the same logic.
