To introduce and describe a scalable, comprehensive metric of social connectedness at the county level that overcomes data availability barriers in empirical social network research.
Constructed the Social Connectedness Index (SCI) using anonymized administrative data on friendship links from Facebook.
Quantified the relative frequency of friendship links across all US county-pairs, as well as between every US county and every foreign country.
Delivered the first comprehensive, nationally representative measure of geographic friendship networks spanning every county in the United States and international partners.
Provided an accessible empirical infrastructure to study the impact of social networks on trade, migration, social mobility, and public health without requiring proprietary coauthorship agreements.
