The Medium is the Messenger A Quantitative Study on the Relation between Social Media Services and Neighbourhood Social Interactions

Internet-based social networking services (ISNS) like Facebook, Instagram, Twitter, and others have revolutionized the way people connect, enabling interactions across great distances. This has sparked a debate about the impact of ISNS use on face-to-face contact, particularly within neighbourhoods. Some argue that ISNS diminish the significance of local physical place and hinder meaningful interactions, especially among neighbours. Conversely, others view ISNS as tools that foster new forms of connectedness and enhance relationships within neighbourhoods by creating opportunities to engage with existing peers. However, there is a significant knowledge gap regarding the varying effects of ISNS on offline social interaction within neighbourhoods. Do different ISNS, including messenger services, Facebook, Instagram, Twitter, and neighbourhood-specific social networks (e.g.nebenan.de), 1 have distinct effects on offline social interaction within neighbourhoods? Are there differences in usage between native residents and migrants? We analyse data from a 2022 postal survey conducted in two German cities (Essen and Cologne), involving 2, 676 residents in 166 neighbourhoods. The results from our multiple linear regression model show that the impact of different ISNS on social interactions varies. Messenger services and neighbourhood-specific social networks have a positive impact on social interactions within the neighbourhood. However, popular social media platforms like Facebook, Instagram, and Twitter do not significantly affect social interactions within the neighbourhood. Additionally, individuals from the native population do have more social interaction with their neighbours compared to those with a migration background.
