The document summarizes a research project examining disability and development in four African countries: Kenya, Sierra Leone, Uganda, and Zambia. The research aimed to understand how socioeconomic development impacts people with disabilities in domains like education, health, employment, and social protection. The key findings were that (1) a disability-development gap exists even where inclusion policies are in place, and this gap tends to widen as development increases, risking people with disabilities being left behind; (2) this gap also exists at the household level, where people with disabilities may be disadvantaged compared to other household members; and (3) existing policies lack implementation and accountability mechanisms, limiting their effectiveness in reducing inequities.
