This chapter examines to what extent and under what conditions the Sustainable Development Goals have fostered a better inclusion and support of poor and vulnerable communities within countries, and of the least developed countries internationally. We start with a conceptualization of inclusiveness as a matter of recognition, representation, and distribution. We then review the role of the Sustainable Development Goals in steering any normative, institutional or discursive changes in favour of inclusiveness within and between countries, drawing on both a Scopus search of all articles published between 2015 and 2020 in the social sciences subject area related to inclusiveness and grey literature. Although research evidence is strikingly limited, our review indicates that rhetoric and action do not match when it comes to the impacts of the Sustainable Development Goals on inclusiveness within and between countries. While vulnerable people and countries are often discursively prioritized in the implementation of the goals, such discursive prioritization has so far not resulted in creating or reshuffling norms and institutions towards inclusiveness.
