Ghana - Ghana Living Standard Survey 4 - 1998, With labour force model

A two-stage sample was selected for the survey. At the first stage, 300 EAs were selected using systematic sampling with probability proportional to size method (PPS) where the size measure is the 1984 number of households in the EA. This was achieved by ordering the list of EAs with their sizes according to the strata.

The size column was then cumulated, and with a random start and a fixed interval the sample EAs were selected. At the second stage, a fixed number of 20 households was systematically selected from each selected EA to give a total of 6,000 households. Additionally 5 households were selected as reserve to replace missing households.


There was no deviation from the sampling design.


Out of the selected 6000 households 5999 were successfully interviewed. One household was further dropped during the data cleaning exercise because it had very few records for many of the sections in the questionnaire. This gave 5998 household representing 99.7% coverage.



In order to get the true contribution of each selected EA in the sample, weights were computed based on the true sizes of the EAs since 1984, using the household listing from the 2000 Population and Housing Census conducted by the GSS. Even though the survey fieldwork was completed about a year ago before the census, in practice, the results will not differ significantly.

To obtain national estimates, the sample figures have to be grossed up by the appropriate factor. The 5998 households covered in the GLSS 4 contained 25,694 individuals and an average household size of 4.3. Using the 1984 population figure of 12.1 million (mid-March 1984) and the official growth rate of 2.6 the projected March 1999 population is about 18.3
million. This gives a grossing up multiplier of 712 (18.3 million divided by 25,964). The corresponding multiplier, when the weights are applied, is 708.
