Quarterly Labour Force Survey 2023, Quarter 3 - 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.

QLFS样本涵盖了南非的非机构人口，唯一的例外是工人宿舍中的个人。居住在机构内私人住宅单位的人员也被纳入统计。例如，在学校园区内，学校主人的住宅和教师宿舍因为属于私人住宅而被统计在内。然而，居住在学校园区宿舍的学生则被排除在外。

抽样程序
---------------------------
QLFS采用由南非统计局执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，该框架是基于2011年的人口普查创建的。母框架中有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。
对于QLFS的每个季度，样本中四分之一的住宅将被轮换出样本。这些住宅将被来自同一PSU或列表中下一个PSU的新住宅所替代。更多信息请参见统计发布。
