Focusing again for the sites off a couple-method message transfers, we within the next analyses the outcome off neighborhood departments of any area system for the five separate teams or submarkets (7 for folks who count individuals separately). We discover that regarding 75 % of all the mutual connections when you look at the the five metropolises try anywhere between some one for the exact same submarket, proving your communities line-up well into the conventional definition: tightly knit communities with a lot of correspondence happening contained in this communities. The choice to separate toward five submarkets is to try to some extent haphazard.
