Every individual is entitled to nationality and the right is well recognized under the Universal Declaration of Human Rights. Statelessness is the condition of lacking recognized nationality and poses significant challenges to sustainable development by impeding access to fundamental rights and resources. This research paper explores the multifaceted impacts of statelessness on individuals and communities, including limited access to education, healthcare, employment, political participation and various other aspects. It examines how these barriers hinder progress toward sustainable development goals (SDGs) such as poverty reduction, health and social equity. The paper analyzes legal, social, political and economic dimensions of statelessness, highlighting case studies from different regions. Furthermore, it discusses policy interventions and international frameworks aimed at reducing stateless populations and promoting inclusive growth. The findings underscore that addressing statelessness is crucial for achieving sustainable development, fostering social cohesion and ensuring human dignity for all.
