[From Summary] This Compendium describes the methodologies currently in use in 95 countries to compile such statistics. The ILO Bureau of Statistics, in collaboration with the ILO Disability Programme within the InFocus Programme on Skills, Knowledge and Employability, has conducted a worldwide survey to analyse the different approaches currently used. A questionnaire was sent to ministries of labour and national statistical offices in early 2003, aimed at collecting information about the availability of statistics of disabled persons, especially their employment situation.
