Direction of better
Lower values are better. Used to rank candidate towns/properties; lower score = stronger fit.
Unit
Values are reported in score_0_100.
Default weight in Safety composite
10% of the Safety composite by default. Users can override this weight in their intake; the displayed score reflects the user's chosen weighting, never a fixed default.
