[Our hypothesis is] “the urban poor in Metro Manila, despite appearing segmented and dispersed, are connected by wide and thin networks and share a kind of common culture. Everyday life in the urban locality, which is based on village endogamy, is assumed to be a type of  complicated and unconscious local social networking, as suggested by Jacobs and Scott (Jacobs 1961; Scott 1998). Such local networks can work across Metro Manila by means of  the chains of  dyad relationships  in  the  kinship-matrimonial  networks  created  by  homogamy;  in other words, the inter-marriages among the poor are induced by the logic in the poverty paradox explained above. The narrow sphere of  marriage determined by poverty and social exclusion will increase propinquital homogamy, namely, inter-marriages among the residents in the neighborhood who belong to almost the  same  income  bracket  and  reside  in  different  but  nearby  localities. This process will promote the formation of  weak social relationships, and thus create subconscious, unorganised, but vast social networks among the urban poor. We term these networks kinship belts.”
“All poor localities in Metro Manila are connnected to each other and form a global homogenous social group.”
