Other kinds of data that go beyond a snapshot in time are needed to capture this kind of complexity, including those derived from panel or longitudinal surveys or from research that focuses on family histories. Other mixed method and interdisciplinary research can support informed policy-making, by providing contextual qualitative evidence to shed light on family dynamics and change. These types of research require generous, long-term investment, ideally from public funds. Lack of data on asset ownership, resource distribution and the economic contributions of each household member limits the understanding of women's economic position within families.
