What percentage of the global population is affected by intellectual disabilities?

The percentage of the global population affected by intellectual disabilities is estimated to be between 1-3%. This figure is supported by research studies and global health surveys that aim to understand the prevalence of various disabilities. Intellectual disabilities can vary widely in severity and can significantly affect a person's ability to communicate, learn, and manage daily tasks. The 1-3% range indicates a significant portion of the population that experiences some form of intellectual impairment, which underlines the importance of accessibility and inclusive practices in various environments such as education, the workplace, and community services.

The other percentages presented do not accurately reflect the most recent data and research on this topic. Studies on disability prevalence tend to focus on the more conservative estimates, leading to the conclusion that 1-3% is the most reliable range for intellectual disabilities globally. This knowledge is crucial for policymakers, educators, and accessibility professionals in order to create effective support systems and interventions for individuals with intellectual disabilities.
