Leaving no one behind:

Leaving no one behind is a clarion call of the 2030 Agenda for Sustainable Development. Promoting equity and ensuring inclusive participation of marginalized and disadvantaged groups is critical for the achievement of the Sustainable Development Goals. Persons with disabilities, older persons and migrants are classified as disadvantaged and vulnerable groups. Members of those groups are among the individuals most likely to be left behind because of the multiple barriers they face with regards to economic, social and political participation. Consequently, policymakers should address their needs.
