Understanding Gender: Beyond Biological Differences to Social Constructions

Few questions in social science look as simple – and turn out to be as layered – as “what is gender?” Most of us grow up treating “male” and “female” as natural categories, with everything from cooking duties to career choices supposedly flowing from biology. But sociologists, philosophers, and feminist theorists have spent the last fifty years pulling that assumption apart. They argue that what we call “gender” is less about bodies and more about the rules, expectations, and power relations a society wraps around those bodies. Understanding this distinction is the first step to making sense of why women, even today, still do most of the dishes.

Sex and gender: Ann Oakley’s foundational distinction

The clearest starting point is the work of British sociologist Ann Oakley. In her 1972 book Sex, Gender and Society, she introduced a distinction that has shaped feminist scholarship ever since. According to Oakley’s original formulation, “sex” refers to the biological division between male and female, while “gender” refers to the parallel and socially unequal division into femininity and masculinity.

Put simply, sex is what your body is; gender is what society makes of it. Sex is about chromosomes, hormones, and reproductive organs. Gender is about everything else – how you are expected to dress, speak, sit, work, cry, lead, or care. Oakley argued that while sex is largely a biological fact, gender is a product of culture and socialisation, not nature.

This was a radical claim in 1972. Until then, observed differences between men and women – that women were “naturally” nurturing, or that men were “naturally” aggressive – were treated as biological destiny. Oakley drew on anthropology, biology, and psychology to show that different societies define masculinity and femininity in startlingly different, and sometimes opposite, ways. If gender roles were truly biological, they would look the same everywhere. They don’t.

Why the distinction matters

The sex/gender distinction does political work. If gender is biological, inequality becomes inevitable – you cannot argue with nature. If gender is socially constructed, then inequality becomes a problem of social arrangements, which can be changed. This shift opened up space to question why certain roles, opportunities, and freedoms are distributed unequally along gender lines.

Oakley extended this insight in her later work on housework, treating domestic labour not as a “natural” feminine activity but as work learned through childhood socialisation and reinforced into adulthood. Children are not born knowing that girls should help in the kitchen while boys play cricket outside. They are taught – through toys, clothes, scolding, praise, and a thousand small everyday cues.

If gender is socially constructed, what exactly does that construction look like? Two thinkers, Michel Foucault and Judith Butler, pushed this question further. Where Oakley emphasised socialisation and learning, they emphasised power and performance.

Foucault: Power, discourse, and the disciplined body

French philosopher Michel Foucault did not write extensively about women or gender, but his ideas about power have been enormously influential in feminist theory. Foucault argued that power is not just something the state or the wealthy “have” and use against the powerless. Power is everywhere – in language, in institutions, in everyday routines. It works through what he called discourse: the accepted ways of talking, thinking, and knowing about a subject.

For Foucault, sexuality and the body are not natural givens but cultural constructs shaped by discourse. Medicine, psychiatry, education, family, law – all of these institutions produce ideas about what a “normal” woman or man should look like, want, and do. These ideas are then internalised. We discipline ourselves to fit them, often without realising it.

Feminist scholars built on this to analyse how femininity is produced through what they called the disciplining of the female body. Sandra Bartky and Susan Bordo, extending Foucault, examined practices like dieting, beauty routines, restricted gestures, and rules about how women should occupy space. None of these are imposed by a single authority. Instead, women learn to monitor themselves – what to wear, how much to eat, how to sit on a bus, how loud to laugh – because deviation invites social punishment. The body becomes “docile,” in Foucault’s term: trained, regulated, and obedient to cultural expectations of femininity.

Judith Butler: Gender as performance

If Foucault gave feminism a way to think about power and the body, philosopher Judith Butler pushed even further. In her 1990 book Gender Trouble, Butler argued that gender is not something you are but something you do. She called this gender performativity.

According to Butler, gender is produced through a ritualised repetition of acts – the way you walk, the pitch you adopt when you speak, the clothes you wear, the chores you “naturally” take on. These repeated acts do not express a pre-existing gender identity hidden inside you. Instead, they create the appearance of a stable identity. We come to believe in fixed “male” and “female” essences because we keep performing them, day after day, and society rewards us for getting the performance right.

Butler is careful to distinguish performativity from theatrical performance. You cannot simply wake up and choose a new gender for the day. The script is written long before you arrive. From the moment a doctor announces “it’s a girl” or “it’s a boy”, you are absorbed into a system of expectations that shape how you will be addressed, dressed, educated, and treated for the rest of your life.

The political payoff is significant. If gender is performed rather than essential, then the rigid binary of masculine and feminine is not a natural law. It is a social habit – and habits, however deeply ingrained, can be questioned, disrupted, and remade.

What this means for women, work, and the home

Theories about sex and gender are not just abstract debates for seminar rooms. They have very concrete implications for how we understand women’s lives – especially in the realm of work and domestic labour.

Consider a familiar scene in many households: a mother returns from a full day of paid work and immediately begins cooking dinner, supervising homework, and managing the family’s schedule. Her husband, who also worked all day, switches on the television. If you ask why, the most common answer is some version of “that’s just how it is” or “women are better at these things.” These are not innocent statements. They are the everyday language of a gender ideology that treats unpaid care work as a natural feminine duty.

The data on unpaid domestic labour

The numbers are striking. According to the National Statistical Office Time Use Survey of 2019, almost 93 percent of working women performed unpaid domestic services for household members, against only 31 percent of working men. Even among married women with paid jobs, higher education or independent income did not significantly reduce their share of unpaid care work. The more recent Time Use Survey of 2024 showed that women spend nearly five hours a day on unpaid domestic and care work – almost eight times as much as men.

Without the sex/gender distinction, these numbers might be dismissed as reflecting “natural” preferences. With it, we can ask harder questions. Why is housework treated as something women are biologically suited to, when in fact it is learned, enforced, and rewarded by social norms? Why does this “natural” arrangement produce an economy in which one half of the population works for free?

The double burden and the cost of invisibility

Sociologists call the resulting situation the double burden or the second shift: women who work for pay outside the home come back to a second, unpaid job inside it. The consequences are not trivial. The marginalisation of women in the workforce is intensified because unpaid domestic responsibilities limit the time, energy, and mobility they can devote to paid employment. Many women drop out of the labour force after marriage or childbirth, or take part-time work that pays less and offers fewer prospects.

This is where Oakley’s distinction, Foucault’s analysis of discourse, and Butler’s notion of performativity converge into a powerful explanatory tool. Domestic labour is gendered because society has decided to gender it – through socialisation that teaches girls to cook and clean, through discourses that frame care as feminine virtue, and through daily performances that make the arrangement seem inevitable. None of it is dictated by chromosomes.

Beyond the binary

Recognising gender as a social construction also opens up room to think beyond the male-female binary itself. If gender is performed and produced rather than fixed by biology, then transgender, non-binary, and other gender identities are not deviations from a natural norm but expressions of human variation that the binary system has historically erased. This is one of the most important contributions of Butler’s work – and a reason her ideas remain politically contested.

It also reminds us that masculinity, too, is constructed. Men are not born stoic, ambitious, or emotionally restrained. They are taught to be these things, often at significant cost to their own well-being. The category “man” is just as socially produced as the category “woman.”

Putting it together

So, what is gender? It is not the same as sex. It is the elaborate set of meanings, roles, expectations, and power relations that a society attaches to bodies it has classified as male or female. Ann Oakley gave us the tool to separate the biological from the social. Foucault showed us how power and discourse shape the very bodies and identities we experience as “natural.” Judith Butler revealed gender as something we do – a repeated performance that produces the identity it claims to express.

Together, these frameworks let us see that the unequal division of domestic labour, the persistent gap in women’s workforce participation, and the everyday rules about who carries the family’s emotional and practical load are not facts of biology. They are facts of society – and what society has made, society can also remake.

What do you think? If gender roles are learned rather than natural, what specific moments in your own upbringing taught you what was “appropriate” for boys or girls? And in your own household today, how is unpaid domestic work divided – and what would it take to change that arrangement?
