Sampling
Sampling Procedure
A stratified two stage probability sample design was used with Census Blocks (CB) as primary sampling units (PSU's) and Agricultural households as secondary sampling units (SSU's).
It was decided to include 2,500 census blocks in the sample. These 2,500 CBS were proportionately allocated between the 25 districts and the two sectors ( urban and rural ), based on the total of Agricultural personnel as at 1981 Population Census.
It was however noticed that the number of Agricultural Households in certain urban blocks were very few. hence it was decided to double the number of urban blocks and to select 5 households from each urban block and 10 households from each rural block.

It was also decided that, the maximum number of blocks allocated to
a district to be not more than 180 blocks and minimum to be not less
than 36 blocks. The number of blocks within districts were adjusted as
above and was readjusted so that in any district, the final number of
sample blocks to be a multiple of 12. This enabled distributing the final
number of blocks over the 12 rounds (monthly rounds). Finally the number
of census blocks (PSU's) selected was 2,664 and the number of households
selected (SSU's) was 25, 340.
