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.

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

The Quarterly Labour Force Survey (QLFS) uses the Master Sample frame that has been developed as a general-purpose household survey frame. The 2013 Master Sample is based on information collected during the 2011 Census. There are 3 324 primary sampling units in the Master Sample, with an expected sample of approximately 33 000 dwelling units. The sampling procedure 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.

The Master Sample is designed to be representative at the provincial level and within provinces at metro/non-metro levels. The sample is divided equally into four subgroups or panels called rotation groups. For each quarter of the QLFS, a quarter of the sampled dwellings are rotated out of the sample and replaced by new dwellings from the same PSU or the next PSU on the list.

南非季度劳动力调查（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。机构内的私人住宅单位也被统计在内。例如，在学校园区内，应统计校长住宅和教师住宿，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。

抽样程序
---------------------------
季度劳动力调查（QLFS）采用了一般用途的家庭调查框架所开发的母样本框架。2013年的母样本基于2011年人口普查期间收集的信息。母样本中有3,324个基本抽样单位，预计样本量为约33,000个住宅单位。QLFS的抽样程序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位（DUs）进行抽样。
母样本旨在在省级水平和省内城市/非城市水平上具有代表性。样本被平均分为四个子组或面板，称为轮换组。对于季度劳动力调查的每个季度，样本中的四分之一住宅单位将轮换退出样本，并由来自同一PSU或名单上下一个PSU的新住宅单位所替代。
