Understanding Gender-Based Wage Differentials and Their Impact on Women Workers

Two people, same office, same role, same hours – and yet, at the end of the month, the pay slips tell different stories. This isn’t a one-off office anecdote; it’s a measurable pattern that economists call a wage differential. When wages systematically diverge along the lines of gender, the difference stops being statistical noise and becomes a structural feature of the labour market. Understanding why this happens – and what it costs women workers – is central to any serious conversation about economic equality.

What are wage differentials?

Wage differentials refer to the differences in pay received by workers across categories – industry, region, skill level, occupation, or, most controversially, gender. Some differentials are considered “fair” in economic theory: a surgeon earning more than a junior clerk reflects differences in training, risk, and productivity. But gender-based wage differentials are different. They persist even after accounting for education, experience, hours worked, and job role. That residual gap – the part that statistics cannot fully explain – is where discrimination quietly lives.

According to the International Labour Organization, women globally earn on average about 20 per cent less than men, though the figure varies sharply across countries. In India, the picture is starker. The World Economic Forum’s Global Gender Gap Report 2024 placed India among countries with notably low economic gender parity, with women earning roughly Rs 40 for every Rs 100 men earn.

The nature and scope of the gap in India

The wage gap in India is not uniform. It widens and narrows depending on the kind of work, the location, and the worker’s position in the income ladder. The Periodic Labour Force Survey (PLFS) 2023-24 captures this well. Among self-employed workers, men earned about three times what women did; among salaried workers, the gap was around 1.2 times; and among casual labourers, men earned roughly 1.5 times what women earned for similar work.

The urban-rural divide

Geography plays a quiet but powerful role. In rural India, women working as agricultural labourers, MGNREGA workers, or in home-based production routinely earn less than men for similar tasks. National Sample Survey Office data has shown that rural women earn approximately half of what rural men earn, while in urban areas, women earn around 60 per cent of male wages. The disparity in rural areas is sharper partly because informal employment dominates – and informal workers have little legal recourse to claim equal pay.

Sectoral disparities

The gap also varies dramatically by skill level. Research drawing on PLFS data shows that women in high-skill jobs earn about 34 per cent less than men in roles such as IT and management, around 21 per cent less in medium-skill roles, and roughly 29 per cent less in low-skill manual work. Counterintuitively, the gap is widest at the top – where education, exposure, and qualifications should theoretically equalise pay.

Why does this gap exist?

Wage differentials don’t appear from nowhere. They’re the cumulative result of decisions, expectations, and structures that begin long before a woman walks into her first job interview.

Occupational segregation

Occupational segregation is one of the largest drivers of the gender wage gap. It refers to the tendency of women and men to be clustered in different kinds of work. Women in India are heavily concentrated in teaching, nursing, anganwadi work, domestic service, and garment manufacturing, while men dominate engineering, finance, logistics, and senior management. The problem isn’t simply that these are different jobs – it’s that “women’s jobs” are systematically paid less, regardless of the skill, training, or social value they require.

This kind of segregation comes in two forms. Horizontal segregation separates men and women into different industries. Vertical segregation keeps women clustered at the lower rungs of the corporate ladder even within the same industry. An IWWAGE analysis notes that segregation creates wage gaps biased against women, particularly in developing economies, by limiting their occupational choices and weakening their bargaining power.

Education and skill mismatches

While female literacy and enrolment have improved significantly, education hasn’t translated into proportional earnings. One reason is that women’s education often does not align with high-paying fields. The Women and Work 2024 report points out that women make up only 28.2 per cent of the STEM workforce, compared to 47.3 per cent in non-STEM sectors. Since STEM jobs typically pay more, this educational pre-sorting widens the wage gap before any hiring decision is even made.

There’s another layer: even when women are equally qualified, they’re often steered toward “safer” or “more suitable” career paths – teaching instead of engineering, HR instead of operations. These steering effects compound over a working life.

Career breaks, caregiving, and the motherhood penalty

The unpaid care economy is one of the most underestimated forces shaping the wage gap. Women carry out at least two and a half times more unpaid household and care work than men globally. In India, this ratio is even higher. Career interruptions for childbirth, eldercare, or family relocation reduce cumulative experience, slow promotions, and shrink pension contributions – a phenomenon researchers call the “motherhood penalty.”

The 2017 amendment to the Maternity Benefit Act, which extended paid maternity leave to 26 weeks, was a meaningful step. But studies have shown a complicated side effect: some employers became reluctant to hire women of childbearing age, reflecting how well-intentioned policies can backfire without enforcement and shared parental responsibility.

Discrimination and the unexplained gap

Even after adjusting for education, occupation, age, and hours, a stubborn portion of the wage gap remains unexplained. Economists treat this residual as a proxy for discrimination – both direct (paying a woman less for the same work) and indirect (undervaluing the kinds of work women tend to do). Negotiation norms also matter: women are often socialised to avoid aggressive salary negotiation, and when they do negotiate, they can face social penalties men don’t.

India versus the world

Comparing India with other economies offers some useful context. The ILO estimates the global gender pay gap at around 19 per cent, with the figure being approximately 13 per cent in low-income countries and 21 per cent in upper-middle-income countries. Iceland, Sweden, and Norway consistently report the smallest gaps because of strong pay-transparency laws, mandatory equal-pay reporting, generous parental leave shared between mothers and fathers, and high female workforce participation.

India’s gap, particularly in informal sectors, is significantly larger than the global average. The ILO’s labour income analysis found that women in lower-middle income countries earn just 29 cents for every dollar men earn – a figure that reflects not only wage disparities but also lower female employment levels.

What policy can do

India has a framework in place. The Equal Remuneration Act, 1976, and the Code on Wages, 2019, prohibit wage discrimination based on gender. But laws are only as effective as their enforcement. The informal sector, which employs the vast majority of Indian women, remains largely outside the reach of these statutes. Pay transparency – a tool that has worked in countries like Iceland – is virtually absent in Indian workplaces.

Standardised wage policies, gender-neutral job evaluation, mandatory pay audits, and stronger childcare infrastructure are the policy levers most commonly recommended by international bodies. The India Leaders for Social Sector analysis emphasises that effective change requires combining legal reform with cultural shifts around caregiving, education, and workplace norms.

The cost of doing nothing

Wage gaps are not a women’s issue alone – they’re an economic drag on the country. A World Bank estimate cited in research on India’s wage gap suggests that the disparity costs the economy roughly 2.5 per cent of GDP annually. Lower female earnings mean reduced household savings, lower tax contributions, restricted consumption demand, and an intergenerational transfer of poverty. When women earn less, their daughters are more likely to drop out of school, marry early, and replay the same cycle.

The World Economic Forum estimates that at the current pace, achieving full global gender parity will take around 134 years – roughly five generations. That timeline alone should make the urgency obvious.

What do you think? If two workers do the same job with the same qualifications, what justifies any difference in their pay – and how would you design a workplace policy that closes such gaps without unintentionally discouraging the hiring of women?
