3. Reference periods

The time period to which income and/or expenditure statistics refer when released/published is from 03/01 to 04/02. These data are collected in the period from 03/01 to 04/02. This survey is conducted 5-yearly. The statistics are published 5-yearly.

SURVEY METHODOLOGY

4. Sample design

The Primary, Secondary and Ultimate Sampling Units are none, none and household respectively.

Stratification:
Areas/districts were stratified using the following criteria:

The sampling frames for the Primary Sampling Unit (PSU) and Ultimate Sampling Unit (USU) were a set of administrative registers (or combination of such registers) and none respectively. Primary Sampling Units (PSU) were selected using probability proportional to size.1 The sample size was 5500 households or other units and 5500 interviews. The overall response rate for the survey was 62.5 percent. Errors/biases were minimized by using an updated sampling frame, an increased sample size.

Enumeration procedure: Enumeration uses a single round survey design in which each reporting unit is enumerated only once. The sample is divided into 26 representative sub-samples. No action is taken to select a smaller set of reporting units for more detailed questioning.

Classification: COICOP is used for classifying expenditure and has 639 separate categories at the finest level.

7. Other Data Collection Issues

The following other topics are covered:

Households are requested to indicate whether durable goods are new or second-hand when their acquisition is recorded.

Non-response: There is no substitution for non-response, whether by non-contact or by refusal.

Non-response is reduced using the following measures:
Reporting errors are reduced using careful instrument design.

DATA PROCESSING, ANALYSIS AND DISSEMINATION

Answers are pre-coded on data collection forms to the extent possible.

The responses are edited office staff.

Extreme values are retained without change. Consumption of own production is included in the estimates, but in-kind receipts are not.

Treatment of owner-occupied housing: Values of owner-occupied housing are included in the total income/expenditure estimates and are valued using the rental equivalent net of housing costs usually paid by owners.

The following information is used in this valuation:

Treatment of selected groups/values in analysis: Some households/units are excluded from analysis because of incomplete response. Missing values are retained without change . Supplementary sources are not used to adjust estimates for under- or over-reporting. No groups are excluded from data analysis.

Weighting:
Weighting factors are used to adjust for:

Sampling errors: Sampling errors are computed for all aggregates and these sampling errors are published.

Tabulation and Analysis: Statistics are presented showing averages per year and statistics are analysed and tabulated for households only.

The following classifications are used for tabulation and analysis of expenditure statistics:
