†Any disability question refers to surveys that were found to have any disability questions that fall under the following categories: functional difficulty or other disability questions.
‡Functional difficulty questions could be the WG-SS or other functional difficulty questions. The number of countries with functional difficulty questions is not the sum of the numbers of countries with the WG-SS and with other functional difficulty questions as some countries have both.
§The number with any disability question does not add to the total number reviewed because not all countries, datasets and dataset-waves reviewed had disability questions.
HFPS, high-frequency phone survey; WG-SS, Washington Group Short Set.
