Stockholm Flows

Cities are defined by the flow of people through them the boundaries of metropolitan areas are drawn based on commuting patterns and on socioeconomic integration; as people move through cities to work, shop, go to school, and socialize, they spread resources and ideas, tying the city together as a single organism. In Project Stockholm Flows, we present a novel metric for measuring the relative flow of people between parts of a city using geotagged Twitter data. Further, we find that socioeconomic similarity is a significant predictor of this flow metric: neighborhoods that are similar to one another in terms of residents' median income, education level, and immigration history are more strongly connected in terms of the flow of people, indicating some level of homophily in the way that individuals choose to move throughout a city's districts.
