The MaiMwana - IFS Economic Survey is a longitudinal dataset of approx. 3200 women aged 17-43 years and their households collected in Mchinji District, Malawi in 2008-09 and 2009-10. The data were collected to investigate the causal effect of 2 randomised health interventions - a volunteer counselling intervention and a women's group intervention - on poverty outcomes (such as consumption, labour supply and investment in health and education of children). These data were collected in collaboration with our partners in Malawi - The MaiMwana Project. The dataset includes information on household demographics, individual schooling, labour supply and health, infant feeding, household consumption, assets, adverse events, health knowledge, family planning and information networks of the woman and anthropometric measurements of young children and their mothers. They are available for use from the UK Data Archive.
