This study aims to examine the relationship between socio-economic status (as measured by education) and multiple disability measures among adults in eighteen sub-Saharan African countries, and to determine whether the strength of this relationship varies across age groups. The analysis uses data drawn from the 2002–04 World Health Survey. The findings indicate that low education is positively associated with poor functional health, and the functional health gap between educational levels increases across age groups. These findings suggest that in sub-Saharan African countries, the under-educated are less successful in post-poning disability to later ages.
