Somali High Frequency Survey 2016, Wave 1 - Somalia

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

Between February and March 2016, the World Bank, in collaboration with Somali statistical authorities conducted the first wave of the Somali High Frequency Survey to monitor welfare and perceptions of citizens in all accessible areas of 9 regions within Somalia’s pre-war borders including Somaliland which self-declared independence in 1991. The survey interviewed 2,882 urban households, 822 rural and 413 households in Internally Displaced People (IDP) settlements. The sample was drawn randomly based on a multi-level clustered design. This dataset contains information on economic conditions, education, employment, access to services, security and perceptions. It also includes comprehensive information on assets and consumption, to allow estimation of poverty based on the Rapid Consumption methodology as detailed in Pape and Mistiaen (2014).

Geographic coverage
---------------------------

The following pre-war regions: Awdal, Banadir, Bari, Mudug, Nugaal, Sanaag, Sool, Togdheer and Woqooyi Galbeed (Somaliland self-declared independence in 1991).

Sample survey data [ssd]

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

The sample employs a stratified two-staged clustered design with the Primary Sampling Unit (PSU) being the enumeration area. Within each enumeration area, 12 households were selected for interviews.

Two different listing approaches were used. In 2 strata with more volatile security as well as for IDP camps, a multi-stage cluster design was employed (micro-listing). Each selected enumeration area was divided into multiple segments and each segment was further divided into blocks. Within each enumeration area, one segment was randomly selected and within the segment 12 blocks were chosen. In each block, all structures were listed before selecting randomly one structure. Within the selected structure, all households were listed and one household randomly selected for interview. In strata less volatile (14 strata), the complete enumeration area was listed before 12 households were randomly selected for interviews (full-listing).

Sampling deviation
---------------------------

EAs were replaced if security rendered field work unfeasible. Replacements were approved by the project manager. Replacement of households were approved by the supervisor after a total of three unsuccessful visits of the household.

摘要
---------------------------
在2016年2月至3月期间，世界银行与索马里统计当局合作，对索马里前战区内的9个地区的所有可到达区域进行了第一次索马里高频调查，以监测公民的福利和感知。该调查对2,882户城市家庭、822户农村家庭和413户流离失所者家庭进行了访谈。样本基于多级聚类设计进行随机抽取。本数据集包含关于经济状况、教育、就业、服务获取、安全和感知的信息。此外，还包括关于资产和消费的全面信息，以便根据Pape和Mistiaen（2014）中详细描述的快速消费方法估计贫困。
地理覆盖范围
---------------------------
以下前战区地区：阿瓦尔、班达尔、巴里、穆杜格、努加尔、萨纳格、索尔、托戈德赫和沃克欧伊加尔比德（索马里兰于1991年宣布独立）。

样本调查数据 [ssd]
抽样程序
---------------------------
样本采用分层两阶段聚类设计，一级抽样单位（PSU）为普查区。在每个普查区内，选择12户家庭进行访谈。
采用了两种不同的清单方法。在2个安全性波动较大的层级以及流离失所者营地，采用了多阶段聚类设计（微观清单）。每个选定的普查区被划分为多个段，每个段进一步划分为区块。在每个普查区内，随机选择一个段，在该段内选择12个区块。在每个区块内，列出所有结构，然后随机选择一个结构。在所选结构内，列出所有家庭，然后随机选择一个家庭进行访谈。在安全性较低的层级（14个层级），在随机选择12户家庭进行访谈之前，先列出整个普查区（完整清单）。
抽样偏差
---------------------------
如果安全状况导致实地工作不可行，则替换普查区。替换由项目经理批准。在三次访问家庭后，由主管批准替换家庭。
