The available global estimates refer to coverage by schemes designed specifically to protect children, persons with disabilities and older persons, but cross-country data on access to other programmes—such as unemployment benefits for persons with disabilities or households with children—is largely lacking. Similarly, information on social protection coverage by race, ethnicity, indigenous or migrant status is scant. Data on the coverage of young people are also lacking. Obtaining such data is no easy matter, but the information base on what appear to be largely underserved groups of the population needs to be improved.
