What percentage of the worldwide population is estimated to have a disability?

The estimate that around 10-20% of the worldwide population has a disability is supported by various research and data sources, including the World Health Organization (WHO). This percentage reflects the diversity of disabilities, which can include physical, cognitive, sensory, and mental health conditions. The estimate considers not only visible disabilities but also those that are less apparent, thus capturing a broader segment of the population that experiences some form of disability. This statistic is significant for understanding the scope of accessibility needs and informs policy-making, accessibility standards, and inclusive practices across different sectors, including technology, education, and public services.
