This study examines the transformative role of self-help groups (SHGs) in the socioeconomic development of rural women in Cooch Behar District, India, and their contribution toward achieving Sustainable Development Goals (SDGs) of the United Nations. In this study, we explored the effect of SHGs on rural women by specifically addressing SDGs, such as no poverty (SDG 1), zero hunger (SDG 2), good health and well-being (SDG 3), quality education (SDG 4), and gender equality (SDG 5). Given this issue, a cross-sectional survey and comparison analyses are needed to assess the socioeconomic development of rural women and their awareness level before and after the participation of rural women in SHGs. The survey conducted as part of this study was divided into three sections, namely, demographic characteristics, socioeconomic development, and awareness level, with each focusing on different aspects. A group of 400 individuals who were part of SHGs completed the questionnaire survey form. The results showed that the participation of rural women in SHGs significantly improved their socioeconomic development and awareness level, as supported by both mean values and t test results. Memberships in SHGs and microcredit programs were the major elements that boosted the socioeconomic development of rural women, which also achieves SDGs 1, 2, 3, 4, and 5. This study revealed that participation in SHGs and related financial services significantly aided rural women in economically disadvantaged communities in accumulating savings and initiating entrepreneurial ventures. Moreover, participation in SHGs was instrumental in enhancing the self-confidence, self-efficacy, and overall self-esteem of rural women. Finally, doing so enabled them to move more freely for work and other activities and to make family and common decisions.
