Women’s groups are a widely implemented and researched development intervention, particularly in South Asia and Africa. Groups encompass many models and aim to address a range of objectives. However, there is no consistent approach to describing their varied implementation models, which hinders the accurate interpretation of evidence and construct validity. Drawing from three recent evidence reviews and research experience with groups, we propose a typology and common reporting indicators to describe women’s groups.

Economic groups, such as microfinance or self-help groups are widely implemented in low-income and middle-income countries (LMICs). Women’s groups are voluntary groups, which aim to improve the well-being of members through activities, such as joint savings, credit, livelihoods development and/or health activities. Health interventions are increasingly added on to existing women’s economic groups as a public health intervention for women and their families.

Livelihoods and microfinance programs for women often show reduced impacts after scale-up. Yet, program scale-up may reduce average per capita costs and maintain cost-effectiveness despite lower impact. This paper presents evidence on the association between program scale, costs, and cost-effectiveness by analyzing how the costs of a large-scale Self-Help Group (SHG) program in India changed from its inception in 2007 to its scale-up in 2019.

The coronavirus disease 2019 (COVID-19) pandemic and some of the associated policy responses have resulted in significant gendered impacts that may reverse recent progress in gender equality, including in sub-Saharan Africa.
