This study provides a comprehensive review of financial inclusion and its socioeconomic impacts, focusing on India and emerging economies. The review identifies 325 papers after refining 620 initial studies using keywords such as financial literacy, financial inclusion, and sustainable development goals. Financial inclusion is defined as the ability of individuals and businesses to access practical and affordable financial products and services, including transactions, payments, savings, credit, and insurance. The review highlights that access to finance for underserved segments is crucial for sustainable socio-economic development. Official banking systems and government initiatives play a vital role in integrating the financially disadvantaged into formal financial systems through campaigns and credit reforms. Socioeconomic programs reinforce each other, fostering the development of children, women, families, and society. The paper discusses the multifaceted nature of financial inclusion, including mobile money accounts, risk management, savings accounts, and remittances. It emphasizes the importance of financial inclusion in reducing poverty, promoting economic growth, and enhancing gender equality. Financial literacy and education are highlighted as critical components, enabling individuals to make informed financial decisions. The paper also explores the role of financial inclusion in supporting entrepreneurship, job creation, and social stability, while reducing inequality. The review uses a systematic literature review (SLR) methodology, analyzing relevant articles from high-impact journals. It identifies gaps in the current understanding of financial inclusion's broader socio-economic impacts and suggests future research directions. The paper concludes by emphasizing the need for continued efforts to improve financial inclusion, particularly in rural and marginalized communities, to achieve sustainable socio-economic development.This study provides a comprehensive review of financial inclusion and its socioeconomic impacts, focusing on India and emerging economies.
