This report examines how to make social protection systems and schemes more inclusive of persons with disabilities. Social protection can play a key role in empowering persons with disabilities by addressing the additional costs they face, yet the majority of persons with disabilities are currently excluded from schemes. Leaving No-one Behind: Building Inclusive Social Protection Systems for Persons with Disabilities identifies a wide range of barriers persons with disabilities experience in accessing social protection to be overcome. It calls for better data on disability, disability-specific and old age pension schemes and expanded coverage; adapting communications about social protection schemes; and improving disability assessment mechanisms.
