Rural Survey 1997

Since the sample design was not necessarily a self-weighting design, weights had to be used. Two types of weights were calculated, namely, person weights and household weights. Household weights were calculated by using the reciprocal of the product of an EA inclusion probability and a household inclusion probability. Relative scaling was done on the household weight due to the changes in EA sizes in the 1996 census sample frame and to take into account the growth rate of the population from 1996 to 1997. Person weights were calculated by first post-stratifying the data by province (former homeland in a province) gender and 5 year age groups. The 1996 Census population figures were used as benchmarks for the post stratum. Since the target areas were former homelands, which are largely African areas, population group was a factor in the benchmarks.
