Ghana - Ghana Core Welfare Indicators Questionnaire Survey 1997, First round

The 1997 CWIQ Monitoring Survey is based on a two-stage, stratified, nationally representative sample of households. The National Sampling
Frame of Enumeration Areas (EA’s) derived from the 1984 census with population and household information formed the basis of the sample design for the survey. The frame was first stratified into three ecological zones, namely coastal, forest and savannah, and then into rural and urban EAs. Additionally, the EAs were stratified into the 10 administrative regions in the country.

At the first stage of sampling, 588 EAs were selected with probabilities proportional to the number of households (PPS-Method). Households within the selected EAs were subsequently listed and a systematic sample of 25 households per EA was selected at the second stage. The survey was designed to yield a total sample of 14,700 households nationwide.


There was no deviation from the sampling design.


The survey was designed to yield a total sample of 14,700 households nationwide but a total of 14,511 households were successfully interviewed. This number from the dataset is short of 3 as stated in both the main report and bulletin.


This sample is not self-weighting, hence, there was the need to compute weights or "Raising Factors" for the estimation
of parameters, based on the probabilities of selection. For details of the computation of weights see Appendix A of the main report.
