How can we measure how common disability is?

In this step, Dr Islay Mactaggart will introduce how we can measure the prevalence of disability – or how common it is in a given population at a point in time. As you have heard throughout this course, the global prevalence of disability is 15%. Prevalence is usually estimated using data from population-based surveys, assessing a randomly selected sample of a defined target population. Dr. Mactaggart also describes how data from population-based surveys can be used.

We would love to hear your thoughts on the presentation. Have you heard the word prevalence before? Do you know the prevalence of disability in your setting?
