2.5 Fieldwork methodology
The PES replicated the census in the sampled EAs, which meant that all methodologies and procedures
for data collection were based on census methodologies and procedures. Extra measures were put in
place to ensure that the PES conducted a more complete audit of the census, for example, extensive
probing was conducted during the listing exercise in order to correctly identify and classify all structures
and dwelling units, including the number of households and the number of persons per household. PES
fieldwork was split into the following three (3) phases; publicity and listing, enumeration and mop-up
operations.
• Publicity and listing were conducted at the same time. Publicity focused on informing and educating
respondents and relevant stakeholders about the purpose of the PES to ensure successful
coverage of all dwelling units (DUs) in selected EAs. 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.
• Enumeration involved interviewing respondents and recording responses in the fields provided in
the PES questionnaire. Self-enumeration for the PES was discouraged, but was used in instances
where the respondent insisted on self-enumeration.
• Mop-up operations were conducted in the form of follow-up visits by senior field staff to households
that could not be contacted during the enumeration period.
Detailed instructions on data collection and other fieldwork procedures, e.g. concepts and definitions,
lines of communication, quality assurance procedures, etc., were outlined in the manuals provided
during training. The following manuals were developed for fieldwork purposes:
• Census 2011 PES Logistics Manual (procedures for distribution and return of materials);
• Census 2011 PES Fieldworker Manual (procedures for publicity, listing and data collection);
• Census 2011 PES Fieldwork Supervisor Manual (procedures for supervision of staff and reporting);
• Census 2011 PES District Survey Coordinator Manual (procedures for management and
coordination of the survey at district level and reporting);
• Census 2011 Map Reading Manual (guidelines on how to use maps);
• Census 2011 PES Quality Assurance Manual (procedures on implementation of quality assurance
measures);
• Census 2011 PES Trainee Workbook on Publicity and Listing; and
• Census 2011 PES Trainee Workbook on Enumeration.
