Post-enumeration Survey (PES) - Statistics South Africa

Statistics South Africa

The PES followed the integrated approach towards fieldwork; whereby one Fieldworker conducted
publicity, listing and enumeration in one EA. This required the appointment of 608 people across the
country to ensure that all EAs in the PES sample were allocated a Fieldworker. A ratio of one (1)
Fieldwork Supervisor for four (4) Fieldworkers was applied; which meant that 152 Fieldwork Supervisors
were to be appointed, but due to the spread of the sample in various districts, this ratio could not always
be applied; hence, a total of 160 Fieldwork Supervisors were appointed.
3.3 Publicity and listing
Publicity and listing commenced on 14 November 2011, and was completed on 22 November 2011.
Publicity was conducted at gatekeeper level, EA level and then at dwelling unit (DU) level simultaneously
with listing. Posters and information sheets were used as publicity instruments. Listing involved the
recording of all structures (including all DUs, number of households in DUs and number of persons in
households) in the sampled EAs in the EA Summary Books.
Quality assurance measures were applied during this process, including the use of global positioning
system (GPS) devices to verify EA boundaries. The approach to quality assurance also involved the
identification of areas in methodology that proved challenging for staff to implement correctly, e.g.
variables in the EA Summary Book which Fieldworkers found difficult to populate correctly. The
supervisory layers were expected to check each Fieldworker's EA Summary Book(s) on a daily basis to
ensure that all listings were done according to prescribed methodology using the provided quality
assurance checklists. Once these areas of improvement were identified by the Fieldwork Supervisor,
Quality Assurance Monitor, District Survey Coordinator and Head Office Monitors, Fieldworkers were retrained
to ensure that they were able to implement the methodology correctly. Quality checks were
intensified at the beginning of listing to ensure that staff understood the implementation of procedures
from the onset. The quality of work from each Fieldworker improved as the survey progressed.
Three (3) EAs were confirmed as vacant; one in Northern Cape, one in Western Cape and one in
KwaZulu-Natal. One EA in Western Cape was also confirmed as an institution upon completion of listing.
Enumeration could therefore not be conducted in these EAs since institutions are out of scope for the
PES. All EAs were verified by supervisory staff and Head Office Monitors before being assigned a final
status.
3.4 Enumeration
Enumeration, which started on 23 November 2011 in all provinces, was completed on 15 December
2011, with mop-up operations being completed on 22 December 2011. Enumeration was conducted in
608 (initially 600 but increased to 608 due to split EAs) enumeration areas (EAs). This process involved
the enumeration of all persons and households who were present on census night (09–10 October 2011)
and PES night (06–07 November 2011) within the boundaries of the sampled EAs. The PES
questionnaire was used for interviewing respondents for each household and recording responses.
