Sampling
The sampling frame is updated every quarter and consists of race, household income, age, home language, gender, province, TV viewing, community size, living standards measure (LSM) and life stages. A new stratified sample is constructed every quarter. The survey covers all races living in urban areas with urban being defined as community size 500+. The period over which the survey data is collected is 4 weeks.
Reference period
Expectation data are for the next 12 months.
Geographic coverage
All provinces are included, however, survey results for only the 4 largest provinces are published, namely the Western Cape, Gauteng, KwaZulu-Natal and the Eastern Cape.
Population coverage
This coverage is representative of 91% of the total urban adult population and 55% of the total adult population. Non-urban blacks are therefore not represented. Although they form a large number of people, their relative purchasing power is marginal given their extreme poverty. On average, there are 2500 adults (1,750 male and 1,750 females of 16 years and older, furthermore it is ensured that 1000 whites, 1000 blacks, 250 coloureds and 250 Indians are included).
Other coverage
2,500 actual addresses are selected at random from a household register of 3 million addresses. The average coverage of their household register is 63% (3 million out of 4.8 million households in South Africa). There are fixed rules for call-backs and substitution.
Key statistical concept
Consumer confidence is equal to the unweighted average of the net balance to the following 3 questions: expected economic performance during next 12 months, expected household finances during the next 12 months and appropriateness of the present time to buy durable goods. There are five reply options which make use of the net balance statistic, i.e. percentage “up” less percentage “down”. The ISIC is used for classification.
Estimation
The official population census of every 5 years is benchmarked.
Weights
The constraint indices are weighted as follows: 0.67 (% of respondents rating a certain constraint to be a serious problem) + 0.33 (% of respondents rating it as slightly serious).
