Quarterly Labour Force Survey 2023, Quarter 2 - South Africa

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

The Quarterly Labour Force Survey (QLFS) is a household-based sample survey conducted by Statistics South Africa (Stats SA). It collects data on the labour market activities of individuals aged 15 years or older who live in South Africa.

The QLFS sample covers the non-institutional population of South Africa with one exception. The only institutional subpopulation included in the QLFS sample are individuals in worker's hostels. Persons living in private dwelling units within institutions are also enumerated. For example, within a school compound, one would enumerate the schoolmaster's house and teachers' accommodation because these are private dwellings. Students living in a dormitory on the school compound would, however, be excluded.

Sample survey data

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

The QLFS uses a master sampling frame that is used by several household surveys conducted by Statistics South Africa. This wave of the QLFS is based on the 2013 master frame, which was created based on the 2011 census. There are 3324 PSUs in the master frame and roughly 33 000 dwelling units.

The sample for the QLFS 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.

For each quarter of the QLFS, a quarter of the sampled dwellings are rotated out of the sample. These dwellings are replaced by new dwellings from the same PSU or the next PSU on the list. For more information see the statistical release.

本季度劳动力调查（QLFS）是由南非统计局（Stats SA）执行的基于家庭的抽样调查。该调查收集了居住在南非且年龄在15岁或以上的个体在劳动力市场的活动数据。

调查范围
---------------------------
QLFS样本覆盖了南非的非机构人口，除一例外。唯一包含在QLFS样本中的机构子群体是工人宿舍中的个体。居住在机构内部私人住宅单位的人员也被列入统计。例如，在学校园区内，应统计校长住宅和教师宿舍，因为这些是私人住宅。然而，居住在学校园区宿舍的学生则不包括在内。

抽样调查数据

抽样程序
---------------------------
QLFS采用由南非统计局执行的多项家庭调查所使用的总抽样框架。本波QLFS基于2013年的总框架，该框架是基于2011年的人口普查创建的。总框架中有3324个抽样单元（PSU），大约有33,000个住宅单位。

QLFS的样本基于分层两阶段设计，第一阶段采用与规模成比例的概率（PPS）抽样PSU，第二阶段采用系统抽样抽样住宅单位。

对于每个季度，QLFS样本中有一半的住宅单位被轮换出样本。这些住宅单位由来自同一PSU或名单上下一个PSU的新住宅单位替代。更多信息请参阅统计发布。
