Yet, less is known whether mobility mixing has any imprint on the social connections of people.Ĭommuting covers a large share of urban mobility 26 and by connecting home with work locations, the places where people spend most of their time, it plays an important role in the spatial formation of social connections 27, 28, 29.

Given the importance of this problem, a growing community has investigated the patterns of mobility in cities to better understand mixing potentials across disparate and diverse neighborhoods 21, 22, 23, 24, which may increase economic prosperity 25. Furthermore, spatial segregation by income also fragments social networks, which can hinder progress and can deepen inequalities 16, 17, 18, 19, 20. However, cities are also known for high levels of segregation 8, 9, 10 where disparate neighborhoods are separated from each other in the urban space 11, 12, 13, 14, 15. Complex interaction networks of individuals in urban areas enabled by population density, co-location, and easy access together made cities the global engines of technological and economic progress 4, 5, 6, 7. Our results inform policy that facilitating access across distant neighborhoods can advance the social inclusion of low-income groups.Ĭities are champions of diversity 1, 2, 3. This suggests a universal relation between long-distance commutes and the integration of social networks.

An above-median commuting distance in cities is linked to more diverse individual networks, moreover, we find that longer commutes are associated with a nearly uniform, moderate reduction of overall social tie assortativity across all cities. In this paper, we aim to better understand income sorting in social networks inside cities and investigate how commuting distance conditions the online social ties of Twitter users in the 50 largest metropolitan areas of the United States. Commuting facilitates the mixing of people from distant and diverse neighborhoods, but whether this has an imprint on social inclusion or instead, connections remain assortative is less explored. Millions commute to work every day in cities and interact with colleagues, partners, friends, and strangers.
