General Household Survey 2013 - South Africa

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

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

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

The survey is representative at national level and at provincial level.

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

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

The sample design for the GHS 2013 was based on a master sample (MS) that was originally designed for the Quarterly Labour Force Survey (QLFS) and was used for the first time for the GHS in 2008. This master sample is shared by the QLFS, GHS, Living Conditions Survey (LCS), Domestic Tourism Survey (DTS) and the Income and Expenditure Survey (IES).

The master sample used a two-stage, stratified design with probability-proportional-to-size (PPS) sampling of primary sampling units (PSUs) from within strata, and systematic sampling of dwelling units (DUs) from the sampled PSUs. A self-weighting design at provincial level was used and MS stratification was divided into two levels. Primary stratification was defined by metropolitan and non-metropolitan geographic area type. During secondary stratification, the Census 2001 data were summarised at PSU level. The following variables were used for secondary stratification: household size, education, occupancy status, gender, industry and income.

Mode of data collection

Research instrument
---------------------------

GHS uses questionnaires as data collection instruments

Data appraisal
---------------------------

In GHS 2009-2015:

The variable on land size in the General Household Survey questionnaire for 2009-2015 should be used with caution. The data comes from questions on the households' agricultural activities in Section 8 of the GHS questionnaire: Household Livelihoods: Agricultural Activities. Question 8.8b asks:

“Approximately how big is the land that the household use for production? Estimate total area if more than one piece.” One of the response category is worded as:

1 = Less than 500m2 (approximately one soccer field)

However, a soccer field is 5000 m2, not 500, therefore response category 1 is incorrect. The correct category option should be 5000 sqm. This response option is correct for GHS 2002-2008 and was flagged and corrected by Statistics SA in the GHS 2016.

摘要
---------------------------
GHS是一项旨在衡量南非家庭生活状况的年度家庭调查。GHS收集有关教育、健康和社会发展、住房、家庭对服务和设施的可及性、粮食安全和农业等方面的数据。
地理覆盖范围
---------------------------
该调查在国家层面和省级层面都具有代表性。
分析单位
---------------------------
家庭和个人
总体
---------------------------
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。调查不涵盖如学生宿舍、养老院、医院、监狱和军事营房等集体居住场所。
数据类型
---------------------------
抽样调查数据
抽样程序
---------------------------
GHS 2013的抽样设计基于最初为季度劳动力调查（QLFS）设计的母样本（MS），该样本首次于2008年为GHS使用。此母样本由QLFS、GHS、生活状况调查（LCS）、国内旅游调查（DTS）和收入与支出调查（IES）共享。
母样本采用了两级分层设计，对每个层内的初级抽样单位（PSU）进行概率成比例大小（PPS）抽样，并对抽样PSU中的住宅单位（DU）进行系统抽样。省级层面采用了自加权设计，并将MS分层分为两个层级。一级分层由都市和非都市地理区域类型定义。在二级分层中，2001年人口普查数据在PSU层面进行了汇总。以下变量用于二级分层：家庭规模、教育、居住状况、性别、行业和收入。

数据评估
---------------------------
在GHS 2009-2015期间：
在2009-2015年GHS问卷中关于土地面积的变量应谨慎使用。这些数据来自GHS问卷第8部分：家庭生计：农业活动的相关问题：问题8.8b询问：
“家庭用于生产的土地大约有多大？如果超过一块，请估计总面积。”其中一个回答选项的措辞如下：
1 = 小于500平方米（大约一个足球场）
然而，一个足球场是5000平方米，而不是500，因此回答选项1是不正确的。正确的选项应该是5000平方米。这个回答选项对于GHS 2002-2008是正确的，并由南非统计局在GHS 2016中标记并更正。
