3. Mapping equal competition areas between businesses
The equal competition model creates polygons around each store. The simpler model uses linear distance to judge polygon size and shape. This method has obvious drawbacks: it does not take into account convenience to the location, and desirability of the store.
We want to use more intuitive factors to estimate which store the consumer will prefer, both location and qualitative factors.

4. The blue squares are larger assisted living facilities, the smaller red dots are smaller facilities. We can also add demographics in block groups if we wish. This is an interesting picture to someone making a buying decision…

7. The Huff Competition Modeling Approach
The chosen factors were average distance to the facility and capacity (number of residents). Other examples of features that might attract customers to an establishment include driving time, store size in square feet, and number of employees.
As an example, houses closer to site 1 would prefer site 1.
All locations in dark blue are assumed to prefer site 1, all locations in blue, site 3.
Notice site 2: the polygon is smaller. Factors reducing the size of the area where consumers might prefer this location may include population in the immediate area and store sales.

9. Insights that matter. Call us.
We are looking to find the areas among local residents in which consumers would prefer one store over another.
The large unused areas away from the sites might be areas of untapped potential, then again, there may be good reasons why they are little used. They deserve more study.
The boundaries of the polygons have a way of being areas of opportunity for new competitors.
