Improving access to family planning in Sub-Saharan Africa has the potential to help women and couples achieve their desired family size and avert unintended pregnancies and unwanted births. It may also have longer-term effects by improving women’s health, educational attainment, and socio-economic status. However, little is actually known about the effectiveness of family planning. In Malawi, Innovations for Poverty Action is working with researchers to measure how an increase in access to family planning—through information, transportation, and reimbursements for family planning services—impacts women’s fertility, health, and well-being.
