Quarterly Labour Force Survey 2023, Quarter 1 - 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.

调查范围
---------------------------
QLFS样本涵盖了南非的非机构人口，除一例外。唯一包含在QLFS样本中的机构次群体是工人宿舍的个体。居住在机构内的私人住宅单元也被统计在内。例如，在学校院落内，需统计校长住宅和教师宿舍，因为这些是私人住宅。然而，居住在学校院落宿舍的学生则被排除在外。

抽样调查数据

抽样程序
---------------------------
QLFS采用由南非统计局进行的多个家庭调查所使用的母抽样框架。本波QLFS基于2013年的母框架，该框架基于2011年的人口普查创建。母框架中包含3324个抽样单元（PSU），大约有33,000个住宅单元。

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元。

对于每个QLFS季度，样本中四分之一的住宅被轮换退出，这些住宅由来自同一PSU或列表中下一个PSU的新住宅所替代。更多详情请参阅统计发布。
