Here is my project map closer to being finished. The ten colored circles are potential sites for a new Walgreens store. The more green a dot is the better choice it is. The darker blue, the less of a good match it is. The score (higher is better) is the number inside the circle.

The black circles are areas within one mile of an existing store.

The red triangles are competing stores.

The score takes into account:

1. Estimated prescription demand within one mile.
2. Traffic volume.
3. Number of competitors within one mile.

These are the rating factors. For close calls or ties, I also have data to consider about:

Current population and growth
Current household counts and growth
Average household income
Average age
Current business population
