The sample design was two-stage in each state, where a systematic sample of 30 census enumeration areas (EAs) was selected with equal probability to form the first stage or primary sampling units (PSUs). The updated 1991 Population Census Enumeration Area demarcation was used. Household listing was conducted in each of the selected EAs to provide an up-to-date frame of housing units (HU) as the secondary sampling units (SSUs). A systematic sample of 25 housing units was subsequently drawn with equal probability within each of the selected EAs, and all the households in each of the selected HUs were canvassed. Thus, in each state, 750 HUs were drawn yielding a total of 27,750 HUs for the country. The sample was stratified by states and was hardly self weighting at either state or national level. Hence, sample weights were used for reporting state or national results.
