Forced Displacement Survey, 2023 - South Sudan

Abstract
---------------------------

The Forced Displacement Survey (FDS) is UNHCR’s new flagship household survey programme designed to standardize, streamline, and build on the existing UNHCR survey landscape to produce high-quality and timely data on people forced to flee. The FDS is comparable across countries over time and aligned with international statistical standards. It has the purpose of providing actionable evidence to inform the government’s operational and policy-related data needs, as well as its humanitarian and development partners.
As a multi-topic survey, the FDS collected household and individual level data on the socioeconomic characteristics and living conditions of targeted populations. Data was collected through face-to-face household interviews, where up to four household members aged 15 and above were interviewed: (1) the head of the household or a household member who was knowledgeable about the household; (2) a randomly selected household member who provided information about individual life experiences; (3) the caregiver of a randomly selected child under five years of age; and (4) a randomly selected woman who gave birth in the last two years.
South Sudan was the first pilot country where FDS has been implemented. South Sudan hosted refugees since its independence in 2011, despite facing multiple social challenges and internal conflicts. By April 2024 South Sudan hosted 450,000 refugees, mostly from Sudan, Burundi, the Central African Republic, and other countries.
The FDS in South Sudan collected data on a nationally representative sample of registered refugees and on a sample of the national population living in proximity of refugees located in the north of South Sudan. Data collection occurred between April and December 2023. The final realized sample of the FDS in South Sudan was composed of around 3,000 households, all located in rural areas. Among them, 68 per cent are refugee households and 32 per cent belong to host communities.

Sampling procedure
---------------------------

FDS survey features up to 4 distinct interviews and aims to represent their respective populations:
• Refugee households,
• Adults aged 15 and over,
• Children under the age of 5 and
• Women who gave birth within 2 years prior to the interview.
The microdata features weights to correctly represent these populations.

The sampling design identified 5 distinctive sampling strata:
• Refugees in Pariang county
• Refugees in Mabane county
• Refugees in Central Equatoria, West Equatoria and Jonglei
• Hosts in Pariang county
• Hosts in Mabane county

The main sampling principle assumed equal sample size for each identified stratum. Due to late changes in the survey design oversampling of refugees in Pariang and Mabane county was introduced in order to achieve more analytical power at the levels below the identified strata.

摘要
---------------------------
《被迫迁徙调查》（FDS）是联合国难民署推出的全新旗舰家庭调查项目，旨在标准化、精简并在此基础上扩展现有的联合国难民署调查体系，以产出高质量、时效性强的被迫逃离人群数据。FDS在时间上跨国家具有可比性，并与国际统计标准相一致。其宗旨在于为政府提供可操作的证据，以满足其在运营和政策相关数据需求，以及其人道主义和发展伙伴的需求。
作为一个多主题调查，FDS收集了针对目标人群的社会经济特征和生活条件的家庭和个人层面的数据。数据通过面对面家庭访谈收集，访谈对象包括15岁及以上家庭成员中的最多四位：（1）户主或对家庭情况熟悉的家庭成员；（2）随机选取的家庭成员，提供个人生活经历信息；（3）随机选取的五岁以下儿童的监护人；（4）在过去两年内生育的女性。
南苏丹是FDS首次实施的国家试点。自2011年独立以来，尽管面临多重社会挑战和内部冲突，南苏丹仍为难民提供庇护。截至2024年4月，南苏丹接待了45万难民，主要来自苏丹、布隆迪、中非共和国和其他国家。
南苏丹的FDS收集了全国代表性难民样本以及居住在靠近南苏丹北部难民居住地的国家人口样本。数据收集时间为2023年4月至12月。南苏丹FDS的最终实现样本由约3000户家庭组成，全部位于农村地区。其中，68%为难民家庭，32%属于东道主社区。

抽样程序
---------------------------
FDS调查包含最多四次独立的访谈，旨在代表各自的人口群体：
• 难民家庭，
• 15岁及以上的成年人，
• 5岁以下的儿童，
• 在访谈前两年内生育的女性。
微观数据包含权重，以正确代表这些人口群体。
抽样设计确定了5个独特的抽样层：
• 巴里昂县的难民，
• 马班县的难民，
• 中赤道省、西赤道省和乔莱伊的难民，
• 巴里昂县的东道主，
• 马班县的东道主。
主要抽样原则假设每个识别的抽样层具有相等的样本量。由于调查设计中的后期变化，巴里昂县和马班县的难民抽样被过度采用，以提高低于识别抽样层的分析能力。
