Street Economics® · Detection #2

NMB AsiaTown

A network and lineage map of the Asian commercial district along 163rd Street in North Miami Beach: the grocers, kitchens, plazas, streets, civic bodies, events and precursors, how the district assembled itself, and what tends to happen after a district like it is seen.

Work in progress. This map is not exhaustive. It shows the result of our research so far, it grows with every release, and every node on it rests on a public source. If something is missing or wrong, submit it.

Current cases: how a district gets seen

Four cases singled out because each shows a different mechanism. Node size and centrality are computed, not adjusted.
