Regarding the area of farms, there was a positive correlation
between the proportion of properties that were 10 ha or larger and
suicide rates (Pearson correlation related to suicide rate for both
genders = 0.22) (Table 2). However, the strongest correlation was
in the 10–50 ha group (Pearson correlation for both genders
= 0.33). In the group of farms bigger than 50 ha, the
correlations were weaker (Pearson correlation less than 0.14).
The suicide rates were directly correlated to a higher proportion of
white people, the Catholic religion and the occurrence of divorce
level of mechanization (Table 2).
