Facebook Social Connectedness Index

Meta

2021

We use an anonymized snapshot of all active Facebook users and their friendship networks to measure the intensity of connectedness between locations. The Social Connectedness Index (SCI) is a measure of the social connectedness between different geographies. Specifically, it measures the relative probability that two individuals across two locations are friends with each other on Facebook. Each entry represents a pair of locations, detailing the strength of social connectedness between them. By doing so, the SCI provides a measure of the relative probability that two individuals from different locations are Facebook friends, offering insights into social ties across regions. The dataset has a a size of 3,9 kB and reflects a specific snapshot in time, with the latest available data from October 2021. The dataset is organized into multiple sub-datasets, each detailing social connectedness at different geographic levels:​

1. Country-Country Pairs:

   • user_loc: ISO2 code of the first country.​

   • fr_loc: ISO2 code of the second country.​

   • scaled_sci: Scaled Social Connectedness Index between the two countries.​

2. US County-Country Pairs:

   • user_loc: 5-digit FIPS code of the U.S. county.​

   • fr_loc: ISO2 code of the country.​

   • scaled_sci: Scaled Social Connectedness Index between the U.S. county and the country.
