Hello,
The leakage/surplus is defined by ESRI as followed: The Leakage/Surplus Factor presents a snapshot of retail opportunity. This is a measure of the relationship between supply and demand that ranges from +100 (total leakage) to -100 (total surplus). A positive value represents 'leakage' of retail opportunity outside the trade area. A negative value represents a surplus of retail sales, a market where customers are drawn in from outside the trade area.
Now my questions are, do you want a negative number or surplus? So this shows that your trade area(s) is/are thriving or do you want positive number or demand (so this shows your trade area(s) is/are thriving?)
Thank you,
Andy Henry
