Two broad categories of voices may be missing in household survey data. The first is people from types of households that are often missed – the very rich and the very poor; and marginalized groups such as indigenous people, unhoused people, or those living in institutional settings.  The second category is people who live in households that are surveyed, but whose voices are missed when only one member of the household is interviewed.   For instance, when only the household head is interviewed, the voices of women, youth, and the elderly may not be heard. This webinar will present recent research on ways to ensure that data is collected on all members of the household as well as to show the added value of exploring the insights gained when more than one person in the household is interviewed.
