The average within-cluster distance for the nine census regions is 5205 units. Ignoring geography, we found that our nine largest clusters held 85 of the cities (87.6% of the total cities observed) and maintained an average within-cluster distance of 4918 units. This amounted to a 5.5% reduction in the within-cluster distance. The largest of these clusters held 33 cities from all but one census region and had a within-cluster distance of 4295 units, meaning that its within-cluster distance was 17.5% smaller than that of the mean within-cluster distance of the nine census regions, the largest of which only held 17 cities.
