SURVEY METHODOLOGY

4. Sample design

The Primary, Secondary and Ultimate Sampling Units are segments (block of 70 households on average), none and dwelling 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 the list of Census enumeration areas and the master sample of households respectively. Primary Sampling Units (PSU) were selected using probability proportional to size. The sample size was 5000 households or other units. The overall response rate for the survey was 85 percent. Errors/biases were minimized by using an updated sampling frame.

Enumeration procedure: Enumeration uses a single round survey design in which each reporting unit is enumerated only once. The sample is not divided into representative sub-samples. A smaller set of reporting units is selected from which information on specific issues is gathered or more detailed questions are asked.

The following other topics are covered:

Households are not 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 more than one repeat visits. 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 by the following:

Extreme values are deleted. 6 In-kind receipts and consumption of own production are included in the estimates. In-kind receipts are valued using:7 the respondent's estimate. Consumption of own production is valued using:7 the respondent's estimate.

Treatment of selected groups/values in analysis: No households/units are excluded from analysis because of incomplete response. Missing values are by the missing data are ignored. Supplementary sources are not used to adjust estimates for under- or over-reporting. they are not excluded are excluded from data analysis.

Weighting:
Weighting factors are used to adjust for:

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