Income/Expenditure/Household Survey [hh/ies]
Series Information
The IES 2005/2006 based on the diary method was the first of its kind to be conducted by Stats SA. Previously IESs were conducted by Stats SA every five years using the recall method. In the recall method a single questionnaire was administered to a household at a selected dwelling unit in the sample. The responding households were required to recall expenditure on all non-durable goods purchased during the month prior to the survey. They were also, in the case of durable and semi-durable goods, required to recall purchases of such goods for the 12 months prior to the survey. The previous IESs also collected information on various sources of income (monetary or in-kind) acquired by households and details about how they disposed of such income (expenditure on goods and services, remittances, etc.). The whole survey was conducted during a period of four weeks.
In line with best international practices, Stats SA decided to change the survey methodology from the recall method to a combination of the recall and the diary methods. Therefore, unlike the previous series of IESs conducted by Stats SA, the IES 2005/2006 was conducted using a combination of the diary and recall methods.

Abstract
The 2005-2006 IES was designed to collect information on items and services acquired by South African households, various sources of income acquired by participating households (monetary or in-kind) and details as to how they spent this income (on expenditure, remittances, etc.). This was accomplished by collecting details of all expenditure by a participating household and all acquisitions of goods and services for the household’s own consumption within a given reference period. Studies of this nature play an important role in evaluating changes in consumption patterns, levels of income and income distribution. The results of the survey serve as an input into identifying the goods and services that should be included in the Consumer Price Index (CPI) basket of goods and services.

Sampling
Sampling Procedure
Sample Design
• A newly designed Master Sample, consisting of 3 000 Primary Sampling Units (PSUs), based on the 2001 Population Census Enumeration Areas, was used as the sampling frame. The Master Sample is used for all household surveys conducted by Statistics South Africa (Stats SA).
• The 3 000 primary sampling units (PSUs) from the Master Sample were representatively divided into four quarterly allocations of 750 each.
• Within each quarterly allocation, a random sample of 250 PSUs was selected every month.
• Eight dwelling units were systematically selected from each of the sampled PSUs for fieldwork. In total, 24 000 dwelling units were covered during the twelve months of data collection for the IES 2005/2006. This process ensured that the sample was evenly spread over the twelve months, while it remained nationally representative in each quarter.

Response Rate
From the 24 000 dwelling units sampled across South Africa, 25 192 households were identified. Out of these, there was a sample realisation of 22 617 households, with the remaining 2 575 households were classified as out of scope due to a number of reasons, such as listing error, vacant dwelling, unoccupied dwelling, etc.

Data Collection Notes
The survey was conducted over a period of one year, from September 2005 to August 2006, with sampled households participating for one month and new subsamples of households starting every month. The data collection exercise involved physical visits to households at the selected dwelling units by trained fieldworkers. Data collection consisted of an extensive interview using a pre-coded questionnaire, which was split and conducted on five separate visits during the survey month. In addition, the selected household was required to record all its acquisitions for the survey month in diaries. A separate diary was used for each of the four weeks of the survey month.
Fieldworkers were hired throughout the period of the survey to complete the main questionnaire by conducting the five interviews and to deliver and collect weekly diaries from households at the selected dwelling units. Whenever it was necessary, fieldworkers were required to assist households regarding how to record their acquisitions in the weekly diary.
