Quarterly Labour Force Survey 2022, Quarter 4 - 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.

南非洲统计局（Stats SA）实施的季度劳动力调查（QLFS）是一项基于家庭的抽样调查。该调查收集了15岁及以上居住在南非洲的个体在劳动力市场的活动数据。

调查总体
---------------------------
QLFS的样本涵盖了南非的非机构人口，但有一个例外。唯一包含在QLFS样本中的机构子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。

样本调查数据

抽样程序
---------------------------
QLFS采用了一个主抽样框架，该框架被南非洲统计局进行的多个家庭调查所共用。本波QLFS基于2013年的主框架，该框架是基于2011年的人口普查创建的。主框架中包含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，对PSU进行抽样；第二阶段采用系统抽样对住宅单元（DU）进行抽样。

对于QLFS的每个季度，样本中的四分之一住宅单元被轮换出样本。这些住宅单元由同一PSU或列表中下一个PSU的新住宅单元替换。更多信息请参阅统计发布。
