Eight months after its fourth round, the World Bank conducted the fifth round of its welfare survey between March and April 2026 \u2014 maintaining momentum in one of the world's most challenging data environments. This round retains coverage of the refugee population and examines seven critical dimensions of wellbeing: food insecurity, displacement, employment, housing, market access, and crop and livestock production. Drawing on a probability sample of 2,019 respondents across 18 states, complemented by a dedicated sample of 1,025 refugee households, the survey delivers the breadth and rigor needed to inform an effective humanitarian and policy response.","coll_dates":[{"start":"2026-03-04","end":"2026-04-25"}],"nation":[{"name":"Sudan","abbreviation":"SDN"}],"geog_coverage":"National (all 18 states).","analysis_unit":"-Household -Individual","data_kind":"Sample survey data [ssd]"},"method":{"data_collection":{"data_collectors":[{"name":"Voluntas","abbr":"Voluntas"}],"sampling_procedure":"The fifth round of the Sudan Welfare Monitoring Survey draws on a rigorous, probability-based sample of Sudanese adults (aged 18 and above) with mobile phone access, achieving nationwide coverage across all 18 states. Crucially, it also captures the voices of adult refugees \u2014 a population often left out of large-scale surveys \u2014 with a dedicated sample concentrated primarily in camp settings.\nSudanese respondents were selected through a one-stage random sampling process from a frame of 45,000 phone numbers provided by the implementation partner, further enriched by approximately 1,000 numbers gathered through household listings and focus group discussions. For the refugee population, a purpose-built sampling frame was constructed from updated household listings in major camps across Kassala and White Nile states, supplemented by random digit dialing (RDD) to achieve the required sample size. Refugee respondents were then drawn through the same one-stage random selection process.\nTo maximize response rates and minimize data gaps, the implementation partner made up to seven contact attempts per number when initial calls went unanswered or respondents were unavailable. In regions with limited or unstable network connectivity \u2014 particularly Darfur and Kordofan \u2014 the survey team deployed a robust random walk sampling technique, ensuring that even the most hard-to-reach communities were represented in the data.","coll_mode":["Computer Assisted Telephone Interview [cati]"],"research_instrument":"The fifth-round questionnaire was built around standardized, internationally recognized tools to ensure data quality and cross-topic comparability. Food insecurity questions were adapted from the World Food Programme's established indicators, grounding the survey in a globally validated measurement framework. The instrument was originally developed in English and subsequently translated into Arabic for administration in the field. It covered six core thematic sections: food insecurity, household characteristics (including displacement and employment status), housing conditions, access to markets, and crop and livestock production.","coll_situation":"1. Fieldwork Organization: The survey was administered through SurveyCTO's Computer-Assisted Telephone Interviewing (CATI) platform by a dedicated team of Voluntas enumerators operating from a centralized call center. The team comprised 59 trained enumerators and 10 supervisors, with each enumerator conducting individual phone interviews.\n2. Data Management: To support timely oversight and maintain rigorous quality control, data from both completed and partially completed interviews were uploaded to the system on a daily basis throughout the data collection period.\n3. Respondent Engagement: Each household interview was conducted with a single respondent \u2014 typically a knowledgeable adult or the head of household \u2014 who was permitted to consult other household members as needed to ensure the accuracy of the information provided.","act_min":"Voluntas organized supervision using interval recording and random call back of a sub-sample. There were 59 data collectors and 10 office supervisors.","weight":"To ensure the survey results are representative and account for differences in selection probabilities across the sample, household and individual weights were constructed using a maximum entropy approach. For Sudanese households, the weighting process anchors to the 2022 Labor Force Survey as the reference benchmark, with its geographic distribution adjusted to reflect current displacement patterns using the International Organization for Migration's Displacement Tracking Matrix (April 2026 update). For the refugee population, calibration weights were derived from UNHCR's population dashboard (March 2026), which provides the most up-to-date demographic profile of refugees currently residing in Sudan."}},"data_access":{"dataset_use":{"conf_dec":[{"txt":"The dataset has been anonymized and is available as a Public Use Dataset."}],"contact":[{"name":"Franck M.
