General Household Survey 2017 - South Africa

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

The GHS is an annual household survey which measures the living circumstances of South African households. The GHS collects data on education, health, and social development, housing, access to services and facilities, food security, and agriculture.

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

The General Household Survey has national coverage.

Analysis unit

Households and individuals

Universe
---------------------------

The survey covers all de jure household members (usual residents) of households in the nine provinces of South Africa, and residents in workers' hostels. The survey does not cover collective living quarters such as student hostels, old age homes, hospitals, prisons, and military barracks.

Kind of data

Sample survey data [ssd]

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

From 2015 the General Household Survey (GHS) uses a Master Sample (MS) frame developed in 2013 as a general-purpose sampling frame to be used for all Stats SA household-based surveys. This MS has design requirements that are reasonably compatible with the GHS. The 2013 Master Sample is based on information collected during the 2011 Census conducted by Stats SA. In preparation for Census 2011, the country was divided into 103 576 enumeration areas (EAs). The census EAs, together with the auxiliary information for the EAs, were used as the frame units or building blocks for the formation of primary sampling units (PSUs) for the Master Sample, since they covered the entire country, and had other information that is crucial for stratification and creation of PSUs. There are 3 324 primary sampling units (PSUs) in the Master Sample, with an expected sample of approximately 33 000 dwelling units (DUs). The number of PSUs in the current Master Sample (3 324) reflect an 8,0% increase in the size of the Master Sample compared to the previous (2008) Master Sample (which had 3 080 PSUs). The larger Master Sample of PSUs was selected to improve the precision (smaller coefficients of variation, known as CVs) of the GHS estimates. The Master Sample is designed to be representative at provincial level and within provinces at metro/non-metro levels. Within the metros, the sample is further distributed by geographical type. The three geography types are Urban, Tribal and Farms. This implies, for example, that within a metropolitan area, the sample is representative of the different geography types that may exist within that metro.

The sample for the GHS is based on a stratified two-stage design with probability proportional to size (PPS) sampling of PSUs in the first stage, and sampling of dwelling units (DUs) with systematic sampling in the second stage.After allocating the sample to the provinces, the sample was further stratified by geography (primary stratification), and by population attributes using Census 2011 data (secondary stratification).

摘要
---------------------------
GHS（综合家庭调查）是一项年度的家庭调查，旨在衡量南非家庭的居住状况。GHS收集有关教育、健康、社会发展和住房、服务及设施获取、粮食安全和农业方面的数据。
地理覆盖范围
---------------------------
综合家庭调查具有全国覆盖范围。
分析单元
---------------------------
家庭和个人
调查范围
---------------------------
调查涵盖了南非九个省份的所有法定家庭成员（常住居民）以及工人宿舍的居民。调查不包括集体生活区，如学生宿舍、养老院、医院、监狱和军事营房。
数据类型

样本调查数据 [ssd]
抽样程序
---------------------------
自2015年起，综合家庭调查（GHS）使用2013年开发的通用抽样框架，作为所有Stats SA基于家庭的调查的通用抽样框架。该抽样框架具有与GHS相兼容的设计要求。2013年的抽样框架基于Stats SA在2011年进行的人口普查收集的信息。为了准备2011年的人口普查，国家被划分为103,576个统计区域（EA）。人口普查统计区域及其辅助信息被用作抽样框架单位或构建块，以形成主样本的初级抽样单位（PSU），因为它们覆盖了整个国家，并且包含对于分层和形成PSU至关重要的其他信息。主样本中有3,324个初级抽样单位（PSU），预期样本量约为33,000个住宅单位（DU）。当前主样本中的PSU数量（3,324）比之前（2008年）的主样本（3,080个PSU）增加了8.0%。更大的主样本PSU数量被选中，以提高GHS估计的精确度（较小的变异系数，称为CV）。主样本旨在在省级层面以及省内城市/非城市层面具有代表性。在城市内，样本进一步按地理类型进行分配。三种地理类型为城市、部落和农场。这意味着，例如，在一个城市区域内，样本代表了该城市区域内可能存在的不同地理类型。
GHS的样本基于分层两阶段设计，第一阶段采用按规模比例抽样（PPS）对PSU进行抽样，第二阶段采用系统抽样对住宅单位（DU）进行抽样。在将样本分配给省份后，样本进一步按地理（主要分层）和人口属性使用2011年人口普查数据（次要分层）进行分层。
