Sample selection
The households were selected using a two-stage stratified random
sample procedure based on the 1997 Pre-Census of Agriculture. In each of the six departments,
villages were randomly selected, with the number of villages proportional to the volume of
agricultural production, subject to a minimum of 10 villages per department. In total, one hundred
villages were selected. In each village, nine households were randomly selected using listed
prepared for the pre-Census. Three alternative households were selected for each village in case
one or more of the nine were unavailable. In a few villages, the number of interviewed households
was eight or ten, resulting in a final sample size of 899 farm households.
Calculation of weights Household weights (also called expansion factors) were
calculated in order to extrapolate from the sample to the national level. Weights are calculated as
the inverse of the probability of selection. Because a two-stage selection procedure was used to
obtain the sample, the weights are calculated by multiplying two terms:
