In developing countries disability represents a correlate of poverty and affects individuals' and households' access to services, labor market participation, education, and expenditures. Elwan's (1999) review concluded that persons with disabilities were more likely to live in poverty than the rest of the population, but the poverty-disability linkage is a two-way relationship as disability can lead to greater poverty and poverty itself makes individuals more at risk of becoming disabled.
It would appear that much of the data required for the analysis of equalization of opportunity, environmental context and participation of persons of disability is collected routinely in LSMS surveys. However, neither the physical functioning data, nor data on the services needs of the population are captured well in LSMS surveys. In this component of the research program, the focus will be on determining the minimum set of additional questions that would need to be added to LSMS surveys in the area of disability that would allow for systematic analysis of the poverty-disability linkages. The work will be based on the work of the Washington Group on Disability Statistics formed by the United Nations.
