A disability is a physical or mental condition that can make it harder for a person to do certain activities or interact with the world around them. It's an incredibly broad term, covering a wide range of human experiences. Far from being a rare occurrence, disability is a natural part of human diversity. It can be permanent, temporary, or situational. Someone might be born with a disability, or acquire one later in life through an accident or illness.

These categories often overlap, and no two people experience disability in the same way. The key is to recognize that disability isn't a flaw, but simply a different way of being.

Traditionally, society has viewed disability through a medical model. This perspective sees the disability as a problem residing within the individual—something that needs to be 'fixed' or cured. If a person who uses a wheelchair can't get into a building, the medical model views the person's inability to walk as the problem.

A more modern and inclusive approach is the social model of disability. This framework proposes that disability is created by society, not by a person's impairment. The problem isn't the individual, but the barriers in the environment and the attitudes of others.

In the social model, if a person who uses a wheelchair can't get into a building, the problem isn't their inability to walk. The problem is that the building was designed with only stairs and no ramp. The barrier is the inaccessible design. By removing the barrier—by building a ramp—the 'disability' in that context disappears.

When we look through the lens of the social model, we can see that people with disabilities face many challenges created by society. These barriers can be sorted into a few main types.

An example of an attitudinal barrier is underestimating someone's capabilities at work because they have a mental health condition.

Environmental barriers are physical obstacles in natural or man-made spaces. This could be a lack of curb cuts on sidewalks, no audio signals at crosswalks, or poor lighting in a room for someone with low vision.

Finally, institutional barriers include laws, policies, practices, or strategies that discriminate against people with disabilities. This might be a company that refuses to provide a screen reader for an employee who is blind, or a school that doesn't offer materials in alternate formats.

These barriers can prevent people from participating fully in their communities, getting an education, finding a job, or accessing healthcare. Recognizing these barriers is the first step toward creating a more inclusive and equitable world.

Understanding that disability is a social issue, not a personal deficit, is the foundation for building environments where everyone can belong and thrive.
