Document: Cities are predicated on extensive and intense socioeconomic interactions. Many of their measurable properties -from the size of their economies, to their crime rates, to the prevalence of certain infectious diseases -are mediated by socioeconomic interactions. These interactions are subject to well known scaling effects, which are magnified by city population size (7) . All of these relationships are tied to socioeconomic networks with average degree (number of social connections per capita) that increases approximately as a power law of city size k(N ) = k 0 N δ , with δ 1/6 (7, 8) .
