The CDC defines Disability Inclusion as “understanding the relationship between the way people function and how they participate in society, and making sure everybody has the same opportunities to participate in every aspect of life to the best of their abilities and desires.”
Accessibility is most commonly defined as the practice of making information, activities, and/or environments sensible, meaningful, and usable for as many people as possible.
The difference between these two is subtle, but important. Disability inclusion is about normalizing the experiences of people with disabilities and working to ensure they are afforded equitable opportunities to do anything that any other member of our society is able to do.
Accessibility is the practical application of removing barriers that exist specifically in physical and digital environments. Both have a goal to ensure people with disabilities are able to participate as efficiently and effectively as everyone else. Both are extremely important to the changes we want to see in the world around us. And both come with considerable complexity.
I see so many people trying to be an expert in both of them. Doing that will burn you out. We still have too much to do to fully realize the potential and impact of both of these things to let each other burn out. So here is my advice: choose one, become an expert in that, and surround yourself with others whose expertise offsets your own so that you can collectively make progress.
No matter which you choose to focus on, invest in gaining a deep understanding of people with disabilities and the various barriers they face. Think about the types of barriers you’re going to focus on removing. If you lean more towards wanting to address topics like representation, equal education and employment opportunities, or societal biases related to disability, a focus on broader disability inclusion topics will likely resonate with you more. If you want to dive deeper into specific functional or technical barriers people face within their environments, the technologies they use, and how to better enable them, I suspect accessibility will be more of what you’re looking for.

Even as a person with a disability, I’d never thought too deeply about the differences between these ideas. I’m excited to learn more. Thank you!
