were males, 68.8% and 57.4% in S1 and S2, respectively. More than half
of the participants (66) in S1 were over 50 years of age, and 46 were
40–50 years old, together comprising 86.8% of the interviewees. These
two age classes, however, were evenly distributed near 25.0% in S2,
with a standard deviation of 6.3% in each age class. Educational levels
were significantly different between the two regions. In S1, 35.9% of
the respondents were illiterate, a proportion similar to that of people
educated at the primary-school level. High-school education was extremely
limited, with only 3.1% of the people in S1 having graduated.
Themajority of the respondents in S2, however, were educated in middle
and high schools, comprising 58.4% of the interviewees, and only
20% of the respondents were illiterate.
