General Household Survey 2008 - 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, employment, health, housing and household access to services.

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

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

Analysis unit
---------------------------

Households and individuals

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

The survey covered 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 students' hostels, old age homes, hospitals, prisons and military barracks.

Kind of data
---------------------------

Sample survey data

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

The sample design for the GHS 2008 was based on a master sample (MS) that was originally designed forthe QLFS and was used for the first time for the GHS in 2008

The sample is multi-stage stratified using probability proportional to size principles. The first stage is stratification by province, then by type of area within each province. Primary sampling units (PSUs) are then selected proportionally within each stratum (urban or non-urban) in all provinces.

Mode of data collection
---------------------------

Face-to-face [f2f]

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

GHS uses questionnaires as data collection instruments

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

The new programs that were introduced for weighting of the general household surveys from 2008 onwards, discard all records with missing values for age, sex or population group (for observations at household level, they are the values for age, sex or population group of the household head). This means that missing values of those variables were imputed. The emphasis was on obtaining reliable imputations rather than a 100% imputation rate, so some persons/households were discarded during the weighting.

摘要
---------------------------
GHS（南非家庭调查）是一项年度家庭调查，旨在精确衡量南非家庭的居住状况。GHS收集有关教育、就业、健康、住房和家庭服务获取等方面的数据。

地理覆盖范围
---------------------------
该调查在全国和省级层面均具有代表性。

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（常驻居民）以及工人宿舍的居民。调查不包括集体居住场所，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

抽样程序
---------------------------
GHS 2008的样本设计基于一个主样本（MS），该样本最初是为QLFS设计的，并于2008年首次用于GHS。
样本采用多阶段分层抽样，采用规模成比例的原则。第一阶段是按省份分层，然后在每个省份内按区域类型分层。然后，在所有省份中，按比例在每个层（城市或非城市）内选择初级抽样单位（PSU）。

数据收集方式

研究工具
---------------------------
GHS使用问卷作为数据收集工具

数据评估
---------------------------
自2008年起引入的新程序，对于一般家庭调查的加权，丢弃了所有缺失年龄、性别或人口群体值的记录（对于家庭层面的观察，它们是家庭头儿的年龄、性别或人口群体值）。这意味着那些变量的缺失值已被估计。重点在于获得可靠的估计值，而不是100%的估计率，因此在加权过程中，一些个人/家庭被丢弃。
