About Data and Statistics

This page has links to sources of data and statistics about disability.

The first ever World Report on Disability (2011), produced jointly by World Health Organization (WHO) and the World Bank, suggests that more than a billion people in the world experience disability. It also points out that disability is difficult to measure for multiple reasons, such as:

  • "Approaches to measuring disability vary across countries"
  • "Censuses and surveys take varying approaches to measuring disability, and the use of these approaches to data collection in the same country often report different rates of disability"
  • Some countries and some data collection approaches "use measures focused exclusively on a narrow choice of impairments" while others us measures that ask about limitations in daily activities, which result in different findings
  • "Question design and reporting source can affect estimates"
  • "Disability is interpreted in relation to what is considered normal functioning, which can vary based on the context, age group, or even income group"

Basically, disability statistics give us important information, but they do not give us the whole story about disability, because there is more than one way to measure disability and many ways to determine who "counts" as a person with disabilities.
