Understanding Disability: Beyond Medical Condition to Social Discrimination

Ask most people to define disability and they will describe a body or mind that does not work the way it is supposed to. A wheelchair user. A person who cannot hear. Someone with an intellectual disability. This is the everyday, medical understanding of disability, and it is not wrong. But it is incomplete. Over the past four decades, disability scholars and activists have pushed for a very different way of thinking about disability, one where the environment around a person matters just as much as the person’s body. Understanding this shift is essential to understanding gender, discrimination and social exclusion in India today.

What does disability actually mean? 🔗

At its most basic, disability refers to a condition of the mind or body that affects how a person functions and interferes with everyday activities. This is deliberately broad. It covers conditions as different as:

• Physical impairments: spinal cord injury, cerebral palsy, and amputation
• Sensory impairments: blindness and deafness
• Communication impairments: speech and language disorders
• Cognitive and developmental conditions: intellectual disability and autism

These conditions do not all arrive the same way. Some are congenital, meaning present from birth, such as certain forms of cerebral palsy. Others are acquired later in life through accidents, workplace injuries, illness, or simply advancing age. A disability can also be static, staying more or less the same over a person’s lifetime, or progressive, gradually worsening over time, as with some neurological conditions. This range matters because it shows that disability is not one fixed category of person. It is a spectrum of experiences that can begin at any point in life and change over time.

The social model: moving the problem from the body to the world around it 🔗

For much of modern history, disability was treated purely as a medical problem located inside an individual’s body, something to be diagnosed, treated, or pitied. Disability rights movements challenged this framing starting in the 1970s and 80s, arguing that disability is, at least in large part, a social issue created by discrimination, inaccessible environments, and stigma rather than an individual defect. This came to be known as the social model of disability, and it draws a sharp line between two words that people often use interchangeably: impairment and disability.

Impairment versus disability 🔗

In this framework, an impairment is the actual physical, sensory, or cognitive difference a person has, such as losing one’s eyesight. Disability, on the other hand, is what happens when society fails to accommodate that impairment. A person who loses their eyesight has an impairment. They become “disabled” when footpaths are broken, when public buildings have no tactile signage, when employers assume they cannot work, and when the world around them is built only with sighted people in mind. The social model argues that as long as a person’s environment meets their needs, the impact of the impairment on their life can be minimised. Where the environment does not adapt, the impairment turns into exclusion, and disability becomes a barrier rather than a biological fact.

This distinction has real consequences for policy. If disability is purely medical, the solution is to “fix” or rehabilitate the individual. If disability is social, the solution is to redesign buildings, transport, classrooms, and workplaces, and to challenge the attitudes that treat disabled people as lesser. Most contemporary disability law, including India’s, now leans toward this second, more social understanding of disability.

Disability as a universal human experience 🔗

One of the most powerful ideas to come out of disability studies is that disability is not a condition that only happens to “other people.” Globally, persons with disabilities are considered the world’s largest minority group, and that number keeps growing. Better healthcare and rising life expectancy mean more people are living long enough to acquire age-related disabilities such as hearing loss, arthritis, or vision impairment. Road accidents, workplace injuries, and chronic illness add to this number every year, in India and worldwide.

This is why disability scholars often describe the non-disabled population as “temporarily able-bodied.” Ageing bodies, sudden accidents, and illness mean that disability is not a fixed label reserved for a small, separate group of people. It is a condition that most humans will experience at some point in their lives, whether briefly or permanently. Recognising this shifts disability from being “someone else’s issue” to a shared human reality that deserves planning and empathy from everyone, not charity from a few.

How caste, class, gender and geography shape disability 🔗

Disability is never experienced the same way twice. How disabling a condition feels depends heavily on where a person lives, their economic situation, their gender, and their caste. Consider two examples. In a rural agricultural community, the loss of a limb can be devastating because so much daily work depends on physical labour, while an intellectual disability might attract less stigma if the person can still contribute to farm work. In an urban, white-collar setting, the reverse can be true. Physical mobility is often easier to accommodate with assistive devices and accessible offices, but intellectual disability can pose greater challenges in a culture that places heavy emphasis on academic performance and professional credentials.

Gender compounds these challenges further. Women with disabilities in India frequently face a double burden of exclusion, encountering barriers tied to both gender and disability at once, whether in access to education, healthcare, marriage, or employment. Class and caste add still more layers. A disabled person from a wealthier, upper-caste family has far greater access to assistive technology, private healthcare, and legal recourse than a disabled person from a poor, marginalised community. This is the heart of an intersectional understanding of disability: it is never just about the body, but about how the body interacts with every other axis of social inequality a person carries.

Disability by the numbers: what India’s data shows 🔗

According to the Census of India 2011, the country had 26.8 million persons with disabilities, making up roughly 2.11 percent of the population, with a higher absolute number of men than women affected, and about 70 percent of disabled persons living in rural India. But most researchers agree this figure is a significant undercount. The census relies on a narrow definition of disability based on self-identification during a brief household survey, and enumerators often skip or rush through disability-related questions altogether.

When broader, internationally recognised definitions are used instead, the numbers rise sharply. The World Health Organization estimates that around 16 percent of the world’s population, or roughly 1.3 billion people, experience some form of significant disability. Applying even a conservative version of that global rate to India’s population suggests the real number of Indians living with disability could be tens of millions higher than what the census records. This gap between official counts and lived reality is itself a form of social exclusion, since people who are not counted are often people who are not planned for.

The law’s evolving definition: the Rights of Persons with Disabilities Act, 2016 🔗

Legal recognition of disability in India has expanded considerably in the last three decades. The earlier Persons with Disabilities Act of 1995 recognised only seven categories of disability, largely limited to visible physical and sensory conditions. The Rights of Persons with Disabilities Act, 2016 replaced this older law and expanded the list to 21 recognised disabilities, giving legal identity to conditions that were previously invisible in policy, including specific learning disabilities, autism spectrum disorder, acid attack injuries, dwarfism, and blood disorders such as thalassemia and haemophilia.

This expansion reflects the social model in action. Rather than defining disability narrowly around a handful of visible physical conditions, the law now acknowledges a much wider range of ways that bodies and minds can differ from an assumed “norm,” and it obligates the state to remove barriers rather than simply treating individuals. The Act also empowers the central government to add further categories in future, recognising that our understanding of disability itself continues to evolve.

What do you think? 🔗

What do you think? If disability is shaped as much by our surroundings as by our bodies, how much responsibility should educational institutions and employers in India bear for redesigning their spaces and systems? And given how differently disability is experienced across rural and urban India, or across gender and caste lines, can a single national law truly capture everyone’s reality?
