highlighted in the economic subsystem represented 53.09% of the total information
weight for this subsystem.
For the environmental subsystem, indicators ENV2 (Total Coliforms—
NMP/100 mL), ENV5 (Nitrate—mg.L
−1 ) and ENV4 (Total Phosphorus—mg.L
−1 )
presented lower entropy and higher information weights, at 60.71%/0.2032;
61.78%/0.2073 and 64.61/0.1920, respectively. The indicators highlighted in the
environmental subsystem represented 61.25% of the total information weight for
this subsystem.
GD8: The social subsystem highlighted indicators S5 (Untreated Water—no.
families) and S6 (Child Mortality-%) with lower entropies and higher information
weights. For S5, entropy was calculated at 73.09% and information weight was of
0.2913. For S6, an entropy value of 76.59% and 0.2534 information weight were
observed. The indicators highlighted in the social subsystem represented 54.47% of
the total information weight for this subsystem.
The economic subsystem highlighted indicator E5 (Gini—dimensionless index)
with entropy of 79.08% and information weight of 0.5629, thus representing 56.26%
of the total information weight for this subsystem.
