Smart City initiatives aim to foster sustainable urban development by integrating technology, infrastructure, and governance to improve the socio-economic conditions of urban residents. In Tamil Nadu, several urban centers have implemented Smart City projects focusing on employment generation, infrastructure development, digital inclusion, and improved quality of life. This study examines the socio-economic upliftment outcomes of Smart City initiatives in selected urban areas of Tamil Nadu from the perspective of citizens. Primary data were collected through structured questionnaires administered to urban residents. The findings indicate that Smart City initiatives have positively influenced employment opportunities, access to public services, income levels, and living standards. However, issues such as unequal distribution of benefits, digital divide, and rising urban costs persist. The study provides insights for policymakers to enhance inclusivity and maximize socio-economic benefits of Smart City programs.
