Background
Sources of household-based labour market
information:
• The October Household Survey (OHS) annually
1995-1999
• The Labour Force Survey (LFS) – in Mar, Sep each
year since 2000
• The General Household Survey (GHS) – in July
each year since 2002
• The Community Survey – February 2007
• The Population Census, 1996, 2001
South Africa

The LFS is the principal vehicle for
collecting current labour market information

The LFS process: Questionnaire
Questionnaire developed in 1999
Supplements added in March & September each year
• Expanded Public Works Programmes (EPWP) since Sep’05
• Agriculture since Mar’01
• Volunteer work since Sep’01
Supplements added in September each year
• Migrant workers since Sep’02 (except Sep’06)
Supplements added intermittently
• Survey of Employers and the Self-employed (SESE) - Mar’01, Sep’05
• Child Labour - some questions included in LFS Mar’05
• Deaths – once off in Mar’02 (subsequently moved to GHS).
Child Labour stand-alone survey in 1999

SURVEY OF EMPLOYERS
AND SELF-EMPLOYED
(SESE)
South Africa

Purpose
• To determine the contribution of the
informal sector to the SA economy
• (through interviewing the owners of
small businesses)
South Africa
7
SESE DESIGN
• Not a stand alone household-based survey
– March 2001, done in conjunction with LFS
– Sep 2005 – screening during LFS data
collection
SESE collection 4 weeks later
– Sub-set of LFS sample
– Only businesses that are not registered
for VAT
Preferred supplier of quality statistics

Challenges SESE 2005
• The screening process implement to
reduce the incidence of fabrication
But
• Collection done 4 weeks after LFS
reference period
recall bias

Addressing challenges in the
informal sector
• A module will be attached to LFS in Sep
2009
• The informal sector module is work in
progress. According to the latest LFS
proportion of people engaged in the IS
was 16%, formal sector – 66. 4%,
domestic work 8% and Agriculture – 8.8%
South Africa
11
The LFS process: Sampling and fieldwork
• Sampling: Master sample introduced in 1999 and
updated on an annual basis.
• Fieldwork: undertaken by contract staff in March and
September
South Africa
12
The LFS process: Data
Processing
• Questionnaires centrally processed after the end
of data collection
• Questionnaires scanned since 2000
• Manual capture of listings
• No imputation
• Data sets ready for analysis six months after the
end of data collection
South Africa
13
The LFS process: Analysis
& Dissemination
Analysis
• Not all the information collected is analysed
• No in-depth analysis of results undertaken at
this stage
• Two unemployment rates 1997- 2005
Dissemination
• Press Conference to release results
• Hard copy, web, datasets
South Africa
14
The re-design of the LFS
• Concerns raised about LFS:
– Frequency
– Timeliness
– Coverage
– analysis
• IMF evaluation and recommendations June 2005
• Decision to re-engineer LFS Aug 2005
South Africa
15
Core objectives of new LFS
To make reliable core labour force indicators
available quarterly, four weeks after reference
period;
and
Supplementary data available annually, six months
after the year end

What re-engineering involves
• Redesigning the master sample
• Clarifying labour market concepts
• Improving questionnaire including translations
• Improving field operations
• Designing editing and imputation system
• Enhancing tabulation and analysis
• Improving dissemination
South Africa
18
Concepts that have been reviewed
• Employment: based only on market activities
• Availability: used to be based in the future
now corresponds with reference week for
employment (past week)
• Formal and informal sector: respondents
used to classify themselves now a more
objective criteria is used
South Africa
19
Benefits of the quarterly LFS
1. Appointment of a permanent fieldwork force
2. Continuous data collection
3. Continuous update of the master sample
4. Better control of field work processes (Real
time Management system)
South Africa
20
Progress to date
1. Development work started in October 2005 until
December 2007
2. Consultants appointed
3. ILO consulted on concepts and definitions
4. QLFS launched in January 2008
South Africa
21
Important milestones

Consultation with other African countries: Dec 2006

Old and new LFS parallel run: 9 provinces Jan – Mar and
Jul – Sep 2008

Establish link factors between old and new LFS (March
series: June 2008

Publish results: 28 Aug 2008

Establish link factors between the old and new LFS
(September series)
South Africa
22
Challenges

Gender mainstreaming not taken care of

More needs to be done in understanding and measuring
the informal sector

Deciding on supplements to be attached to QLFS

Perceived break of series even with link factors

Management of full time permanent fieldworkers.
