SurveyCTO Webinar Series: Update your household rosters over time
In this second installment of SurveyCTO’s webinar series, we show you how to update your household rosters by combining baseline and endline household rosters into one list in the SurveyCTO platform. We do so by assembling a choice list that captures all the members of a household, both new and previous. This choice list can be created in an endline survey, as well as in any midline surveys.
Our Story
