(a)

The counts include total resources located within the final set of block groups analyzed. The count of resources analyzed is slightly larger than the counts reported here, because the analysis is based on all resources within ½ mile buffer of the analysis area.

(b)

Resource densities are based on kernels with 0.5 mile radius. Mean block group densities are reported per square mile/per 10,000 people.

(c)

Health Opportunities were created by scaling and equally combining supermarkets/produce store, retail area, and recreational facility activity densities.
