How Scoring Works
Each tract is scored by counting bus stops, parks, and food access points inside its boundary and then dividing those counts by tract land area. To keep very small tracts from getting inflated values, the calculation uses a minimum area of 0.25 square miles.
Those normalized densities are scaled to 0-100 using a log-based comparison to the highest tract value citywide. The final accessibility score is a weighted average of the transit, parks, and food scores based on the slider settings.
