The document discusses how data and data-driven innovation can impact liveability in cities. It explores the emerging data ecosystem in Rotterdam and how both public and private actors are collecting more data from cities and citizens. While the government currently retains most control over liveability, commercial players are gaining more data and influence. This could shift the balance between public and private control over liveability issues if business models start directly impacting factors like public space and social cohesion. The implications for policymakers are that they may need to address how to ensure liveability retains its public character as data integration and new commercial services expand.
