This manual asserts that accurate disability statistics are very important for the ability to determine the needs of specific individuals, because although two individuals may share the same impairment, they may face different types of difficulties in their daily lives. Therefore, information about an individual’s functional status is crucial for determining their social needs and assistive technology needs.
This manual is based on initiatives to improve disability statistics and measurement by promoting a common definition and methodology that is based on the International Classification of Functioning, Disability and Health (ICF). It is intended to enhance the reader’s understanding of the ICF-based approach to disability measurement. It provides guidance for understanding how to collect data regarding disabilities. It also covers data structuring, analysis, and dissemination.
