More quantitative evidence is needed using rigorous methods, for instance evidence based on longitudinal data and as part of policy evaluations. More internationally comparable data on disability is required for the quantitative evidence to develop, especially in low- and middle-income countries where studies are scarce. Qualitative and participatory research is also needed, especially to investigate unmet needs, and the consequences of extra costs.
Disability is significantly correlated with poverty in Vietnam, according to data from the 2006 Vietnam Household Living Standards Survey, especially when the extra costs of living with a disability are taken into account. This disability-poverty link is also associated with lower educational attainment, an important factor in determining poverty and productive economic activity in general, both for household-based businesses and wage employment. Not taking into account these associations and the extra costs of disability will make some poor disabled people invisible in poverty statistics and impede efforts to reduce poverty.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
