Methodology of rankings

On the overall map, for each location we assigned a score out of 40 based on the 4 available metrics. Each metric is scored between 1 to 10 as seen below using a linear equation.

Each location is then ranked from 1st to 116th based on its weighted score. When using individual filters, the data is reranked based on either a score out of 10 (due to 1 metric) or 20 (due to 2 metrics).
