From the selected point the survey
group started moving northwards to find the first tent in the first
cluster in the section. Following that, the
group interviewed seven consecutive households living in the tents.
Then the group continued their way at
least about 500 meters forward and then turned left at the nearest
minor street or alley to find the first tent in
the second cluster. Again, they interviewed seven consecutive
households living in tents.
Five hundreds meters was considered
in accordance with the limited physical ability and fitness level of
group members, especially females, to walk
after completing the first cluster.
The supporting idea for including the
minor streets and alleys residents along with the main streets ones
was the possible differences between their
accessibility to health care services or opium abuse.
