This note sets out the arguments for extending the sibling cross-section collected in Young Lives Round 3 (2009) to a panel in Rounds 4 and 5. It is a non-technical synthesis of two background notes from an economic and health perspective1, with some additional information and arguments. We point out three main gains in terms of content from collecting the panel of sibling data, as well as noting that extending the amount of information collected would considerably add value. Finally, without making calculations we assert that collecting sibling data would be a relatively low-cost addition to the existing survey.
