Data is a strategic resource, and how democracies govern it shapes both their economies and their security. Rules on data privacy, cross-border data flows, and platform accountability increasingly define the transatlantic relationship and the contest with authoritarian models of digital control. This hub follows the data agenda: data privacy and data protection, data governance for platforms and algorithms, cross-border data transfers between the United States and Europe, and platform accountability for the security risks of data held by strategic rivals. Fellows and analysts examine how to protect citizens’ rights and data privacy while keeping the digital economy open and competitive, and how strong data governance and platform accountability can coexist with innovation. Explore analysis and commentary on data privacy, data governance, and the digital economy.
