High-high tracts are surrounded by tracts with high median housing values and their values are significantly higher than their neighbors, and the inverse is true for the low-low. For the tract that has a significant high-low (low-high) relationship with its neighbors, median housing values are high (low) in this tract and it is surrounded by tracts with significantly lower (higher) housing values. The figure was created by authors using ArcGIS software version 10.8.
