Sampling
Sampling Procedure
The sampling frame for the IES 2010/2011 was obtained from Statistics South Africa’s Master Sample (MS) based on the 2001 Population Census enumeration areas (EAs).
The scope of the Master Sample (MS) is national coverage of all households in South Africa and the target
population consists of all qualifying persons and households in the country. In summary, it has been designed to cover all households living in private dwelling
units and workers living in workers’ quarters in the country.
The IES 2010/2011 sample is based on an extended sample of 3 254 PSUs, which consists of the 3 080 PSUs in
the Master Sample and a supplement of 174 urban PSUs selected from the PSU frame. The IES sample file
contained 31 419 sampled dwelling units (DUs). The 31 419 sampled DUs consist of 31 007 DUs sampled from
the 3 080 design PSUs in the Master Sample and 412 DUs from the supplemented 174 urban PSUs. In the case
of multiple households at a sampled DU, all households in the DU were included.

Data Collection Notes
The IES 2010-2011 collected data by means of a household questionnaire and weekly diaries. A household was in a sample for a period of four weeks. The survey instruments were administered in stages at
different visits during the four weeks of data collection. A module was administered at the beginning of each week.
different visits during the four weeks of data collection. A module was administered at the beginning of each week.
Questionnaires
Questionnaires
There were four modules in the household questionnaire with eighteen subsections. The first module collected general household data and data on household members. Modules 2 to 4 collected data on consumption expenditure, household finances and income. The diary was a booklet in which the respondent recorded weekly expenditure data. A household completed a different diary for each week of the survey period.
Data Processing
Other Processing
Data collected from the IES 2010/2011 annualised to ensure data comparability: Diary data was multiplied by 26 weeks to get an annual value. The questionnaire data was multiplied by 12 months if the COICOP (Classification of Individual Consumption by Purpose) was defined as monthly. The reported expenditure data was benchmarket to March 2011, which was the midway point of the survey year. All
expenditure before the end of February 2011 was inflated to March 2011 prices and all expenditure after March 2011 were deflated back to March 2011 prices using Consumer Price Index (CPI) data.
