Social networks form the backbone of social and economic life. Until recently, however, data have not been available to study the social impact of a national network structure. To that end, we combined the most complete record of a national communication network with national census data on the socioeconomic well-being of communities. These data make possible a population-level investigation of the relation between the structure of social networks and access to socioeconomic opportunity. We find that the diversity of individuals' relationships is strongly correlated with the economic development of communities.
社交网络构成了社会和经济生活的支柱。然而，直到最近，人们还没有可用的数据来研究国家网络结构的社会影响。为此，我们将全国通信网络的最完整记录与社区社会经济福祉的全国人口普查数据相结合。这些数据使我们能够在人口层面上调查社交网络结构与获得社会经济机会之间的关系。我们发现，个体关系的多样性与社区的经济发展密切相关。
