Sampling Procedure
The target number of respondents per country is 500 individuals, representing one household unit/registration group per interview. The study is designed so that only one member of each household/registration group is interviewed. One member of each household was selected from UNHCR database. To compensate for nonresponse, an oversampling factor of 6 was applied, i.e. 3,000 contacts were provided for reaching the targeted 500 respondents, in each country. Longitudinal participants, who in the previous wave agreed to be reinterviewed (1,345 respondents overall, see table above), were sampled by certainty in the current wave. They were amended with fresh sample from the total universe, discounting units that in the previous wave were refusing to participate or declined the request to be recontacted. All other units were part of the eligible universe the “fresh” sample was selected from.
The sample was implicitly stratified based on two variables: registration group structure and time of arrival to the host country. The group structure dimension considers the following three categories: single adults, adults with children, and multiple adults without children. Time of arrival segments were retained from previous wave (those arrived in Feb-Mar 2022 and those arrived Apr-Aug 2022), adding a third segment for those who arrived since the previous wave survey, in the September- November period
