Social sustainability indicators are represented by the percentage of residential
areas within 400 meters from community facilities (AF), happiness index (HI), and
demography (DM) (Tables
12
,

).
AF
0.6149
The most important criterion
HI
0.1171
The least important criterion
DM
0.2680
The second most important criterion

3.3 Sustainability Map
Sustainability maps are produced for each indicator based on the formula pre-
scribed in MurniNet. These maps represent the sustainability of each planning
block
according
to
spatial
indicators.
There
are
three
sustainability
scores:
